Great battery, long-lasting. The only downside is that my wife finds it difficult with her small hand, to remove the battery from the equipment having to push both sides in at the same time with one hand. Could there be an easier way. We both love Ryobi products. The Ryobi strimmers are fantastic. The best strimmer on the market in our opinion. Thank you

An additional battery was an essential although expensive purchase enabling a selection of Ryobi tools to be used continually during lockdown in our home and garden.

Ideal as I have a number of Ryobi tools and this battery can be used for all of them
The Ryobi multi tool lithium battery that I bought is ideal for what I'm looking for and compliments the other Ryobi tools I have.When you compare prices with other makes then not only does Ryobi match the others for quality but it beats them, hands down, for price.
Bought the battery for my angle grinder & soldering iron. Give you the extra reves for cutting & grinding & also great for soldering. Takes a couple off hours to charge. Great all rounder for the 18V tools.
Got this battery for my ryobi garden strimmer and hedge trimmer the battery lasted for an hour continuous use and with the light display for charge level is good to keep an eye on the charge that is left would highly recommend this battery to anyone for there ryobi collection.
I bought the battery from B&Q as it was priced cheaper than most other stores, plus it was available at my local B&Q store. It took an hour to fully charge and been used in a drill just a few times and is still fully charged.Seems well made and hopefully will last a long time.
Great idea. I have used Ryobi Power Tools for years. I own other professional power tool brands but I love my Ryobi drills. The newer tools seem to be built much better an they used to be. I have four different tools made by Ryobi and they all use the same battery. One of them I must have had for 10 years + now and still going strong.
great power and charge retention. Fast charging and charge level indicator
A replacement battery for my chain saw and other power tools. Now fully charged. A word of warning to any new users, keep these batteries charged up even during dormant periods otherwise they may not charge up again!
