This battery has really good power for its size and weight. I much prefer to have two of this size battery instead of one larger more powerful one. I find having this lighter battery makes the work easier and if I have two of them I can have one in the charger while I am using the other one. I have had it for a few weeks and used it with my hedge trimmer and it provided all the power I needed to do the job. I wasn’t sure how long the battery would run when it is fully charges so I tested it with my Ryobi Jet Fan Blower running continuously and it ran for 12 minutes before I heard a change in the pitch of the blower. It probably would have run a little longer, but I feel this represents the amount of time the battery would continuously run this blower at maximum performance. I tried recharging the battery right after shutting the blower off, but the charger wouldn’t charge the battery. I checked the instructions and it said the charger wouldn’t charge a battery if it was too hot. After the battery cooled, I tried again and the battery took a full charge.

I have used this battery for only a few weeks. And so far I am very impressed with its capability to deliver the power required to run my RYOBI tool to its maximum capability. I am also impressed with its run-time between recharges. To date, I have been able to finish every task before the charge ran out. So I do not have available a good time estimate of how long a full-charge will last. After finishing a job where I am using the battery in a tool I place it in the recharge base to bring it up to full charge in preparation for its next use. However, I have timed how long it takes to fully charge the battery pack when only one of the four charge level indicators are lit and that is approximately 1.5 hours. The battery comes with a three year limited warranty. And like all the RYOBI products I am currently using it appears to be well-built, so I expect it will provide many years of issue free service. See attached photographs. Well done RYOBI.

40-VOLT LITHIUM-ION 2.0 AH BATTERY, these new Lithium batteries really pack a punch now a days. Battery technology is leaps and bounds from the 1990's and these batteries are it. The batteries have a button and you can press to see how much JUICE is left which sure is a bonus now! For such a powerful Lithium battery but yet very light when adding to your tool.

                                  Meeting expectations but I wish it would last longer or charge faster for the price point. I’ll probably try another brand next time.
