Brought these when on a deal so got 2.
They are genuine
Charge fine
Last as long as my original 1yr old battery.
Mmmm. Now what do I do with all the 1.5ah and 2ah batteries I have.
I bought this 5 amp battery it was a bit pricey but you get what you pay for it’s good quality build and it seems very sturdy I would recommend this to other people.
You cant use it out of the box unless you have also bought some bar & blade oil. A shame there’s no heads up in the literature. Otherwise this is a great bit of kit.
I have one of these ‘Ryobi RB18L50’ 5.0 amp and its a good battery compared to other 3rd party of similar capacity it is slightly heavier and probably using higher quality cells.
However, this is now old stock on sale, as the current 5.0amp battery sold by Ryobi is the RB1850X, different design and more expensive, but maybe more durable if they have not sat in a warehouse for x amount of time.
I have about 20 Ryobi base units 5ah and 4ah are the only ones I use
Thank you to Amazon easy to
use Good value for the money
already have this product and was just adding it to my collection of Ryobi products great product. just be carful there are loads of fakes on the market if its to cheap its fake or a copy
Great price, prompt delivery, great quality, would buy from this seller agai
The only poor reviews on this seem to be from people who thought they were buying the power of a petrol saw, but driven by battery.
I have a lot of wood that is about as thick as your thigh, or less, from trimming trees, and occasionally thicker.
This is perfect for the job of trimming the trees and then sawing into ca. 16″ lengths.
It cuts half the speed of my petrol saw, and that’s not a bad thing if you’re working in tight quarters or at awkward angles.
Working single handed, I can easily get about an hour and a half work out of an original Ryobi 4Ah battery.
Not sawing all the time, of course, but positioning for cutting, throwing into wheelbarrow etc.
Lighter to use than a petrol saw, but don’t forget helmet, boots and chaps! It’ll still cut your leg off, even it is battery.
Assembly and maintenance is very easy a well. Just check the tension every half hour of cutting, and check the saw oil level. It keeps well lubricated.
Get a file (and handle) for it, and a quick swipe every hour or so at the angle indicated in the chain, and it’ll cut quicker.
Replacement chains and bars very easy to get, and cheap as well, but *do* learn to sharpen your chain!
Happy and safe sawing!
Lasts much longer than the normal battery which come with my Ryobi drill
This battery out performs every like for like third battery I have. Its rugged and charges quickly with the quick charge, giving plenty of usage time on some of my most demanding tools.
Really happy with it albeit a little on the pricey side, but I would recommend it.
I have had this a while, it has lasted quite a long time without discharging power, I only use it every now and again for small tasks. Bought for use with a circular saw, drill driver and other riobi products if I buy more of the one plus range.
I have a large number of Ryobi One+ power tools so I’m obviously a fan but I always baulked at the cost of the genuine Ryobi batteries and so purchased a number of pattern ones from Amazon. While initially they did the job and gave me a good stock of batteries over time they have started to fail or lose charge. Each time one fails I replace with a genuine Ryobi equivalent and the difference is remarkable. Tools like the leaf blower have more power with a genuine 5amp than with a clone 5 or 6amp and it’s the same with impact drivers and drills.
Clones are good to get a stock of batteries but in the long term genuine works out cheaper.
Great quality and durability. Battery life depends on the tool you use for the job, would need other Battery on standby if a full days work planned
I’ve been using Ryobi One+ tools since the day they came out and it would take a lot to make me switch. I’ve never had an issue with the batteries personally, even the NiCad ones that are 15 years old are still useable. The latest ones are superb batteries and with their built in management system can be used to power all sorts of other items.
Good long life battery, make sure you have a fast charger as it can take time to charge, possibly overnight.
Used to power my garden blower, needed longer life in the battery to allow me to clear garden of leaves.
Just arrived and it is not the battery shown at amazon, charging now will go to ryobi web site to check it is real will add results later had this problem with amazon before with canon batterys. update have been on ryobi website and the battery checks out ok just do not like getting something I did not order going by the picture at time of purchase.
Use for garden strimmer and circular saw. Lasts ages and seems to hold the charge for a long time on the shelf. Has useful remaining charge indicator on the battery.
These kind of batteries are so useful being interchangeable with all other Ryobi appliances.
Great quality and great communication with the seller recommended seller
Arrived in great condition and time
Battery life is super to non, washed a people carrier with only one bar, 3 bars left.
I am now totally again and can not shout loud enough the build quality, battery life, 100% reliability
Ryobi is now the top hand tool in my workshop and will be recommending this brand to all my friends and customers robust bright colour stands out
Now it’s green and grey Ryobi to stay top buy and at a great price,wow regards mike
Totally transforms the power level from the useless standard battery . Well worth i
Bought to use with my Ryobi strimmer. Based on others reviews I went for the 5.0Ah 18V battery to be confident I would be able to strim the front and back lawns without the battery needing a charge mid way. I am impressed as on the full charge I have been able to do the strimming on both front and back lawns twice now and the battery still shows 4 out of a 5 bar charge. This is incredible.
It may be expensive but you get what you pay for and I have every confidence in this battery compared to cheaper alternatives.
Expensive but it’s worth it for longevity for the rest of my ryobi products
Nice long lasting charge from battery with tool showing no sign of slowing during use even when battery almost empty all this type of battery seem a bit pricey to me now more are being used let’s hope prices fall
Recommend
I love the Ryobi one+ range, have multiple gardening tools available from them and I’m slowly replacing my tools when they wear out to join the range. The simplicity of the plug and play is fantastic and the tooling is of high quality. I already had 1 of these batteries and while the charge time is great, it doesn’t quite cover all my garden jobs (30 foot long Laurel to cut) and a reasonable sized front/back garden to mow. 2 is more than sufficient. They are very expensive though and there are cheaper alternatives available, while they’re not recommended for use, if I require another one should the lifespan on these batteries start to diminish I’d be tempted to try them owing to the cost.
If you keep the grass cut regularly the 30 minute battery is adequate im very pleased with my purchase
The battery appears to be fine, although it wasn’t til it was removed from packaging I found the little addendum sheet that advises it’s only compatible with certain chargers, and although my existing fast charger is lithium compatible, it’s not so with this specific battery, either that or there is a fault with the battery but won’t know that ’til I purchase a newer generation charger…
This 5.0Ah Battery, 18 V is well worth the extra money, it seems to go on forever before the next charge, really pleased.
Purchased for my father as his current Ryobi batteries are lower voltage and he wanted something more powerful and longer lasting perfect choice for him.
The bigger the battery (amp hour) the better. AS the saying goes… you get what you pay for! I got mine when on offe
Love it I can get my job done now thank amazon for a quick delivery
Very good battery for my lawnmower as smaller Ryobi batteries just don’t last long enough. feel over priced though. It is just a battery.
A good addition to my Ryobi one range. Really gives extra power and run time to my strimmer.
I bought it for my circular saw and it does last long time as advertised
Quality product. Lasts long even with full power. Fast to charge.
Delivery on time excellent value for money and fits a lot of the robins products so don’t have to buy lots of other batteries. We purchased long side the knapsack battery operated paint sprayer lasted a long time and still had power left after painting. 40 metre fence
Always liked Ryobi tools, they feel solid and well built without the price tag compared to some more expensive makes, do when a 4amp Ryobi battery came up
in a flash sale for half price, I snapped it up
Seems to go on and on without needing a charge, worth buying the ryobi rather than aftermarket battery.
Best to buy the pukka ryobi batteries
Tried the fakes……load of kak!
I bought this battery on February 8th and charged it immediately. When I came to use it it was completely discharged. It’s not fit for purpose. I didn’t use the battery for a month but my two other battery’s still had charge
Purchased to accompany my new Ryobi cordless jigsaw thinking that my 2.5Ah battery (used for Ryobi drill and hedgecutter) wouldn’t be powerful enough to cope with a long duration of cutting. This battery certainly does the trick and it’s fair to say that I tend to conk well before it does! Charges quickly too – whilst I haven’t run it completely flat yet, it’s fully charged in less than an hour.
So much better than the unbranded cheaper versions, which couldn’t cope with the power drain on my mitre saw
Great battery but the packaging is dire. It’s that thick brittle plastic and it’s moulded in such a way that it is virtually impossible to get into. It will take you 5 – 10 minutes!
Bought to replace a dud ryobi battery which didn’t last long, having lots of ryobi products now it was a must really, so far its working well.
Brilliant,
I bought a non gen 6ah last about 18months ago firstly I had to re-solder the contact onto the battery then and from first getting it the charge didn’t seem to last as long as I thought it would.
Then when I got the genuine ryobi battery the charge last at least 4x longer the power output for such as sanders is definitely more.. When I i used it on my belt sander you could here the difference and it never stopped and started like it did on the nongen one
In conclusion don’t buy non gen. There cheap, but so inferior, and only really good for drills (not hammer)
Excellent battery.
Dies off quickly the first couple of times but once it’s been drained and charged a few times it lasts longer.
Works well with higher power tools like the brush less angle grinder.
The charge indicator lights are a useful addition too
Good quality, bought it to use it hopefully over a long tome with my Ryobi tools. A bit expensive but when you buy original products it’s expected.
Worth the money. Got a cheap one and broke within the week. This just keeps going and is powerful.
Lasts 30-45 mins constant use.
Love this battery, so reliable, have bought many of them.
Swap out for a new fully charge battery and off you go.
Great product!
did what I expected it do to, i liked that you can see the charge in the battery by seeing how much charge remains
I bought two 5.0Ah batteries to bolster up power for my ryobi collection which is ever growing. They are best used in the more power draining tools like the recip saw and garage vac cleaner, as these both drain smaller batteries really quickly. They are very well made and if they last half as long as my other 1.5Ah, 2.5Ah and 4.0Ah batteries, I will be a happy man. They are definitely overpriced for the UK market, but then what isn’t? They are half this price in the states and if you want a 9.0Ah version you have to shell out 170 sheets. Not a chance!
Not cheap but waaayyy more grunt than the no name knock offs.
Everything just works better and longe
This battery is a must have for all of the Ryobi One + power tools. Get this with the charger and you have an absolute powerhouse. I’ve never even depleted one of these batteries on any job I’ve had to do. A sound investment.
Was great in the beginning but after 3 months it stopped working. Three days later tried it again and it worked. Maybe intermittent fault. When its working its great.
Thus is a good battery for the Ryobi products. It’s quick to charge and hoods it well as long as it has been taken off the item your using it on. I like the power indicator on this model so you can easily see how much charge there is left before starting anything rather than getting half way through and it giving up. Would recommend this battery .
I got 2x 5.0 mAh batteries to use mainly with my new lawn mower.
They charged ok and seem to last a long time.
No complaints apart from maybe being a little expensive.
Good investment if you are going to invest in Ryobi products.
Great addition for my ONE+ system – backup use only and working well… OME a better option than copies.
Bought the 4amp because it was no difference in price over lower capacity batteries. Glad I did because I’m not considering investing in other power tools and I’m confident this will keep them going for hours.
Can’t comment on battery life or longevity yet because I’ve only had this a few hours.
Great, but. I have around 10 Ryobi + 1 tools but will probably stop buying for one reason. The batteries are way too expensive. If you compare the cost against the Likes of Makita,Dewalt and Milwaukee Ryobi are by far the most expensive. They are seldom on offer and rarely available in twin packs. I have purchased a couple of third party batteries but these do not have anywhere near the run time of a genuine Ryobi, and when using them with Brushless tools the tool frequently stops for no apparent reason. Was looking at the latest variant, the 9AH but refuse to pay 160 + for a single battery. Am now switching to Makita.

The transporter bashed in the Amazon box terribly.
The plastic casing on battery was virtually impossible to open, took over quarter of an hour wrestling hacking sawing, cutting. Should have tried a blow torch.
But the battery was intact and was pre charged for testing. I gave it a full charge and it looks good.
I’ve got a couple of 5Ah batteries and have ordered a couple more. I’ve tried the cheaper alternatives and they don’t work in all tools – pay the extra, get something that works with your Ryobi One+ range properly.
You’ll see plenty of reviews on the different tools that putting in a 5Ah battery “makes it more powerful” – it doesn’t do this, in the same way as putting a bigger fuel tank in a car doesn’t change the motor, it just lets it run for longer.
The 5Ah batteries are quite hefty so for more delicate tools/jobs you might want to cut the weight with a lighter unit and recharge more frequently.

I used this 5AH to pair with my Strimmer & Leaf blower for the garden. My garden is roughly 200sqm and once I have done the edges with the strimmer & leaf blowed the patio down the battery generally only moves down 1 bar / 2 at the very most.
Solid construction, battery life indicator, Not too heavy – great product all around as has been my experience with Ryobi so far.
Tried some other after market batteries but had to send them back as they just did not work. The genuine Ryobis work a treat.
Great that you can use of different tools on Roybi one range. Would recommend getting a bigger battery as battery life isn’t that long when using on garden trimme
Great product, only used lightly,6 months and still not charged it .
As usual a great ryobi product the larger batteries are far better than the smaller ones,And don’t weigh that much
more when in use on a tool.
They cost far too much, but are the best by far! Cheaper alternatives break very quickly in my experience.
I got these on a business prime deal. They were ok but then 3 of them have died. They were bought at different times in the year. I was very disappointed and amazon refused to replace but only refund me and then lost one battery which I was not refunfed for. I suspect these were not genuine items and have come from a secondary seller.Ryobi with not entertain any warranty claims if i bought them off amazon even though they were new! I would not really recommend them due to this. Becarefull as some items are fakes….
Its heavy, but what can you expect for 5Ah capacity. Used on angle grinder it last so much longer than my smaller batteries. It was cheaper than buying two 2.5 Ah units, probably due to the weight, but it works well for me.
Typically battery powered tools are only as good as the battery. Ok its pricey but it lasts well and doesn’t add a whole load of weight compared to the 2.4Ah one the tool came with.
Great power to my list off Ryobi devices. Nothing to complain about yet and I have used it on a number of jobs.
This is great and last a while! i had 2x 1.5Ah batteries that were fine for odd jobs around the house with my power tools (drill etc) then i picked up some outdoor power tools, specifically the leaf blower… and 3-5 mins was not ueful. SO i picked this up and it lasted long enough for me to finish the garden. also using it on my power tools is fine but this obviously adds weight so if using with a drill consider that.
The only downside (and there really is only 1) is its so damn pricey! but once you pick one up, then you only really need the tool from there on in and plug this and go.

I brought this instead of gambling with the alternatives on offer and I’m not sorry, it powers my Ryobi One Plus hedge trimmer and some with no problems, highly recommend.
Used as primary battery for my ryobi + one tools excellent run time
Too early to rate in detail but seems good and is flexible.
I only use the 5Ah batteries and find them powerful and long lasting, get a Ryobi RC18150 fast charger and you’ll be full charge in an hour!
I dont know why you are asking these questions ” its a battery for christsake “
Works an absolute treat and if charged on the quick charger doesnt take too long.
It’s life has so far been excellent for me.
Having read some reviews about batteries not holding charges, I was a little nervous about ordering. When received I immediately charged it. Was completely devoid of charge when first plugged into charger, and took about 8 hours to fully charge up. Not used ye
Brilliant last a long time and doesn’t take ages to charge easy to get in and out of power tool with no struggling required.
Definitely a good addition to the oneplus range. Charge and go for a lot longer than the smaller batteries in the range. Necessary for longer periods of DIY and gives a nice weight to the tools
It is expensive but don’t be fooled by cheaper aftermarket batteries. They don’t last so you end up paying more than the cost of this one which is dependable so you’ll never be left stranded at a job.
I only had 2 small batteries and they didn’t last very long. Also I have 6 Ryobi tools so I needed additional batteries. This is great, lasts a very long time.
Still to be fully tested but so far thoroughly impressed.
Great product. Good battery life for a 2.5 works well in my sander.
A little experience but will worth it they last a long time before recharging
Cannot score on battery life due to only just got it and do not know how long it will las
I re placed my old battery with this one and it works fantastically
Makes a lot of difference to charge life compared to the standard one, particularly with the more power needy tools ( grinder, jigsaw etc).
Powerful and long running.
Use it in my strimmer.
This is a quality battery from a great company. I have used Ryobi products for many years and never been disappointed with the build quality.
Lasts long enough to keep my allotment paths tidy. Use it with my mower and strummer. Expensive though.
