Great screw driver that takes this type of battery. The new version sucks it has a non removable battery that dies so quick. I took it back and dug my old one out of the goodwill bag and bought this additional battery just in case the old battery goes bad. Strong and long life battery A+++ 4volt system

Bout the 4v battery to go along with my screwdriver kit . Works great for my cabinet projects and small jobs around the house especially being a first time home buyer. Would recommend this product for the ease and functionality of it. Great tool!

It’s a battery. It puts out 4 volts. It fits my Ryobi screw driver.

The small compact drill and the extra battery for small to medium projects works great. I love the two speed drill and the 4volt battery and thats why i got an extra battery to keep working on small long work time projsects.

I like the older model ryobi 4-volt electric screwdriver. The older model has 1-quick bit changer built in 2-adjustable torque clutch. I wish ryobi would bring these features back to their 4 & 8 Volt electric screwdrivers. The batter chargers need to some how show the charge level of their batteries. I prefer electric screwdriver with both of these features plus a speed switch , 1-slow speed and 2- fast speed. I include a pic of the better older screwdriver model.

I found out long ago that the more batteries you have with battery dependent tools the quicker your job will go by not having to wait for batteries to charge.

Own several TEK4 tools and was excited to find a great deal on some batteries.

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!

Battery works great. Just wish there were more tools to use it in like the flashlights they used to have and the radio headphones
