40V 7.5AH LITHIUM-ION BATTERY
40V 7.5AH BATTERY is rated 4.8 out of 5 by 37.
Rated 5 out of 5 by from This battery is a BEAST! I bought two of these for my Ryobi Pole Saw, which came with a puny 2AH 40V battery. This 7.5AH battery is heavy, which actually helps to balance out the chain saw on the end of the pole assembly. I definitely have to use the shoulder strap to support the whole assembly, but with this battery, it's a tree-limb-cutting monster!

Rated 4 out of 5 by from Big Battery I purchased this battery as part of the package for a Whisper Series snow blower. I have used the snow blower once on a light snowfall and it performed well.

Rated 5 out of 5 by from Great Durability!! Bought this 7.5 AH battery and was able to cut an entire yard front and back with 3 light left. I was surprised how little battery was used.

Rated 5 out of 5 by from Great extended runtime for 40v mower! Bought the 7.5ah 40v battery to replace a 4ah for my ryobi mower. It’s an older generation mower, so at first it didn’t physically fit properly. However, some modifications to the battery bay with a dremel and we were off to the races! Love that I can now mow my 1/3 acre non stop with basically 1/2-3/4 of this single battery (depending on how tall/thick the grass is.

Rated 5 out of 5 by from Great Battery! Wow! I'd been having problems making it through the small front yard, till I got this battery! Not only does it do all of the front yard, it'll finish the small back yard at the same time!

Rated 5 out of 5 by from Great powerful Battery Picked this up to go into the Ryobi power inverter as a 4th battery. Powerful battery well built, little on the heavy side but so far so good. I have used on the Whisper blower and last for a very long time.

Rated 3 out of 5 by from Wanted more battery life I purchased this after using a 4Ah battery. I expected almost twice the battery time but probably only got a 50% increase over 4Ah.
