Rated 5 out of 5 by from 40 Volt - 2.3 Amp hour I purchased a 40 Volt Ryobi Mower two years ago. It came with 2 batteries. Loved the mower but I needed both batteries to cut a very small patch of lawn which was ok, not great. Last summer, I decided to get a get both the edger and a hedge trimmer to avoid buying the extra power that I needed to do my lawn in one try. This was a pricey solution to a "Ryobi Battery" issue. This year, I met with a Ryobi rep at the store and I purchased two 40 volt 5 amp hour batteries during a promotion event. They work great. Since my lawn has lots of clover, you need this kind of power to make a clean cut. This is the power you need to get your lawn and edging done the same day!

Rated 5 out of 5 by from Charged Bought this 5 Amp Hour High Capacity Battery as a second battery to go along with our last years purchase of the Ryobi cordless lawnmower that came with a 2.6 Amp battery. The 5 Amp battery is more than sufficient to power the lawnmower on our 100'x100' property. The original 2.6 Amp battery has performed the task in ideal conditions, but the 5 Amp is definitely the number one go to for a start to finish job without needing a charge/battery swap. Very pleased with this cordless option which in my opinion is equivalent to the gas version, without the mess/weight!!

Rated 3 out of 5 by from Ryobi battery Not fair to rate it now. This is my fifth. Two were replaced free by Ryobi because they didn't last a year. I say ask me in a year.

Rated 1 out of 5 by from Battery size has increased I just purchased this 5 Ah Ryobi battery as an addition to the 5 Ah battery that I already have for my Ryobi mower, snow thrower and lawn edger, all purchased a few years ago. My existing battery fits all of these tools, but this new battery is slightly higher and hence does not fit into the snow thrower. The description of the battery on the Home Depot site includes: "This battery works with all RYOBI 40-Volt tools and chargers." - obviously not true. What gives, Ryobi?

Rated 1 out of 5 by from Battery does not fit mower despite Ryobi claims. I have a 4 year old Ryobi mower. RY40108. The battery is dead. Started dying last year. It's a 5ah battery. The store recommended a 6ah as they said the 5ah is not made. The 6ah does not fit the mower, despite claims that all 40V fit Ryobi mowers. NOT TRUE. I see this 5ah, but only available online. Do I risk buying it only to be disappointed again? What battery fits for the same or better performance that I was getting for the first 2.5 years. M

Rated 2 out of 5 by from Good for 2 years Originally I was very impressed with Battery , as I could cut my grass almost # times in one charge . However , after keeping Battery in the house and periodically charging it (as suggested by Ryobi) It didn't last to finish a single cut . Because of late spring I didn't see this problem until only 1 month after Warranty had expired . Now I have to purchase a new one . Thus a poor rating .

Rated 4 out of 5 by from Powerful and Long Lasting Bought to replace a 2.5A that died after being replaced on warranty. Already had another 5A that came with mower that is still going strong after 2 years. The 2.5 A was a bonus. No wonder they were giving those away as they suck! I have two 5A ones now so one of us can mow and one whipper snip. If alone one battery lasts for both. Yard is about 30’ by 50’ in front and in back.

Rated 1 out of 5 by from Poor performance I tried to cut my lawn this morning before the rain expected later today and at 45 minutes of cutting the battery was dead. This is ridiculous that I am unable to cut a small city lawn on one battery charge. We purchased a second battery 2ah (as a back up) and had to return it because it wouldn't even cut half of my back yard on a full charge. Ryobi I am not impressed!

Does a 40 volt 5 amp battery allow the tool/lawn mower etc to run stronger/better performance vs a 40 volt 4 amp battery or will it just give a longer run time?

Asked by: Frank
It will give you longer run time.

Is this battery compatible with the RY40108 lawn mower?

Asked by: jldmlt
Hi Jldmlt, Yes all of our 40V batteries are compatible with our 40V mowers. The 5AH high capacity will give you longer run time compared to our 3AH 40V models. Thank you, Ryobi Canada Team

Will the 5ah fit in the chainsaw? Need another battery as it always dies out just as I’m getting into the groove of the work. Thanks

Can this be charged with an old first generation 40V charger? Or do I need a new style one?

Asked by: Datsuntech
I’ve used my original charger to charge the higher capacity battery with no issues.

Does a 5ah battery hold a charge 25% longer than a 4ah battery? The cost is much more than 25% greater than a 4ah battery. Would seem 4ah battery a better deal. No?

Asked by: Big Guy
I use this for my chainsaw and it seems to be the only battery that performs both for apparent torque and for longevity.   The battery is worth the extra cost,   Not sure about percentages but definately more than 25%
