Rated 3.8 out of 5 by 36 reviewers.
Rated 2 out of 5 by Consumer not on a deadline product I bought 2 drivers and the 2 batteries and then 4 batteries after the first 4 quit working to do a project that required a lot of screw tightening. The battery performance became a problem since they went dead 1/2 way through the day, charging is a overnight event not quick at all. July 1, 2014
Rated 1 out of 5 by Battery died Had the Tek4 kit (suppression headphones, drill, flashlight) batts worked great in light and headphones and recharged a few times. Battery died under load in 1st use in drill and wouldn't take a recharge, 2nd battery did same thing a week later in the drill. Only had for 2 months, returned to store for full refund as Ryobi CS wanted whole kit shipped to them and only warranted repair for 30 days. October 22, 2011
Rated 5 out of 5 by Good product I have about six of these batteries for different products. I like using this battery and ryobi's led flashlights because you don't have to worry about throwing away a battery withpower left over because with led flashlights, you may have a period of bright light, then a long period of dim light. Not with ryobi's battery. You always have a strong beam of light. Now they need to make a """" head lamp""" August 1, 2012
Rated 4 out of 5 by Ok It is a small battery that can hold can hold a charge but not very strong. May 6, 2014
Rated 5 out of 5 by Spare Power to go I bought 2 so that I have back up for my Tek4 driver, and light. I have the RP4400 High Intensity light, and the AP4302 Rapid Charger that comes with a USB cord, and can actually charge these batteries enroute to a job site. January 29, 2013
