My last lot of batteries lasted a long time. Very happy with the performance from these new style batteries and they are a lot lighter.

Needed extra batteries. My previous battery had lasted so long and is still going (bought in 2013) but I wanted an extra so those times I needed to do more with multiple tools. Very convenient to have it usable on all the tools. Charges quickly and very durable.

Happy with my purchase. Plenty of power for my purposes & a charge has a long use time. Do wish they’d make these batteries slightly smaller to make changing them easier for smaller hands

I was debating whether to pay the extra and get the high performance 5 AH batteries, but it was so worth it. My tools actually have more grunt. Especially useful when using my blower ;).
This particular size has really good run time and perfect for heavy loads such as angle grinder, drop saw and 1/2 inch impact driver.
I am happy with my ryobi battery operated tools, as the battery can be used for all of them. Also, Ryobi has a very good extended warranty, and they stand by it
Great battery. Been using Ryobi 18 volt batteries and skins for years. Never let me down.
I have been using RYOBI for years, they have a fantastic range of tools and batteries. Their warranty is second to none. Buy, use and enjoy!
Have used these batteries and RYOBI tool for a number of years and have never been disappointed. Quick to recharge and hold their charge for a long timeframe
Nothing beats genuine batteries. Was on a camping trip recently and my one single 5Ah HP genuine battery lasted the entire weekend powering my air pump, bug zapper and handheld vacuum.
