Rated 1 out of 5 by Jane of all trades from Battery & charger not working from day 1 Bought drill kit and never able to work. Put bag away year later take it out. Nope still not working. Don’t bother even if “on sale” not worthy of your time.

Rated 5 out of 5 by Scottls from Incredible little powerhouse! I have the little Tek4 screwdrill and this battery will outlast any full day of use if not a few days or better. I am an electrician and prefer a small screwdrill that fits in my pocket when I have a house full of switches, receptacles, and other devices to install and don't want and over sized tool that will strip out the screws or weigh me down with size and bulk that is not required for the task at hand. This light weight battery fits the bill!

Rated 5 out of 5 by NASAMan from Long-lasting Battery I've used my 4V Lithium-Ion battery in my Ryobi driver for a month now. I has reliable power and is powerful enough to drill pilot holes for screws in wood without slowing down. I didn't recharge the battery right away and was amazed that two weeks later, it was still able to drive a handful of screws for hooks inside a cabinet. Good value, great performance.

Rated 5 out of 5 by Brian balzer from Fantastic value I love this thing. I work Hotel Maintence And I carry this on me at all times, and use it several times a day. I love the battery life and the Ability to easily switch out the battery if it dies. This little thing packs quite the punch. It is much stronger than what I expected. I ordered a second one and the third battery just because

Rated 2 out of 5 by Firetruckfixer from Charge problems Ever since I bought this battery the charging of it didn't last as expected. 1 hr. Max! Maybe 25 screws will buy again. I boughht the product to take the place my old ryobi screw driver with permanent battery.

Rated 5 out of 5 by Rhet from Little battery with a BIG punch! I bought an extra 4v battery so I would always have one charged. But these batteries hold their charge for a very long time. 1-3 months. It’s amazing how much power is packed into this tiny battery!
