40V 2AH Lithium-ion Battery

40V 2AH Lithium-ion Battery is rated 4.6 out of 5 by 128.

Rated 5 out of 5 by Goofyjim from Job Finished on Time! Last Fathers day my wife bought me a Ryobi push mower and it came with a 40V 4.0 AH battery. My yard is fairly large and I was worried that the battery would not last for the entire yard. When the grass wasn't high I could just barely get the yard completed. When it's high, the battery would run out and I would not be able to finish the job. Purchased this 2.0 AH battery to help finish the job, and it enabled me to do just that. Was well worth the investment. Now using both batteries, I do not need to charge them both after each mowing and thus helping to extend both of their lives a bit more.

Rated 4 out of 5 by sawyer60 from Good but not quite an hour runtime I bought the RYOBI 14 IN CHAIN SAW WITH BATTERY AND CHARGER and It is a great saw. Cuts like a gas powered saw and the chain is excellent. My only gripe is you have to buy the chain from Ryobi parts dept and get charged more for shipping and handling than what the chain costs. You should be able to buy this chain at home depot who carries the Ryobi brand. Oregon does not make a chain that fits this saw (yet). Be careful buying a chain that looks compatible but is not. The book says you have to buy their chain. Do your research. The cbattery holds up pretty good but not for an hour. Charges quick though and the charge indicator on the battery is a great feature. I would highly recommend this saw.

Rated 5 out of 5 by Mimi Teresa from Just enough I bought the 2.0 AH, not realizing for just a little more I could have gotten a 4.0 AH or 5.0 AH. The 2.0 does everything it is supposed to do, but I would recommend paying a little more and getting the higher AH so that you have more battery run time. I went back and purchased the 5.0 AH and the 2.0 allows me run time anytime I am recharging my 5.0 battery, so everything is good. One thing to remember is that the 5.0 AH weighs more, so if you are just doing small jobs and prefer not having to hold up more weight, the 2.0 AH will be perfect.

Rated 5 out of 5 by Raleigh1001 from Good life I purchased this battery about a month ago. I was looking for a 2.6 AH battery to match the one that came on my Ryobi String Trimmer, but decided on this one instead. It has good life, as I have used it on my string trimmer as well as my Ryobi Blower and it held up for approximately an hour with no problem. It was run almost constantly during that hour. At the end of that time it was on it's last life indicator, but it did the job. If you have a normal house that sits on a half or quarter acre this battery should handle your needs.

Rated 5 out of 5 by t0912 from Good Power I have plenty of Ryobi 18v tools and batteries. This was for my 1st venture into Ryobi 40v tools. I bought a 40v chainsaw and a 40v pole trimmer. Since cutting down branches and smaller tress take some time, the 1 battery that came with the tool wouldn't last for the whole job. I bought 2 extra 40v batteries so I'd always have power. When 1 runs out, I can put it on the charger while using the others. This provides plenty of power, though not as long as the larger ones, but works great.

Rated 5 out of 5 by SleepySumo from Good battery life This battery was included with the Ryobi electric lawn mower that I purchased a month ago. The mower is great. I wasn't sure the battery would last for the entire yard and I was right. However, it does last long enough to finish about 75%. It's way more than I thought it would be though. I bought a smaller A/hr battery to finish the job, so it's all good here. I really like the Ryobi line and am planning on more pieces. Definitely gonna get another of the bigger batteries.
