First ever battery powered tool I have bought. I have been very stubborn for a long time but when I bought the 4v Tek 4 I knew I wanted a second battery and I am glad I did.

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!

I purchased a replacement batter for my TEK4 drill driver. It restored the missing performance as my original battery was several years old. These drill drivers are great for compact spaces and light duty work around the house. The price was appealing and it was great that it is stocked in store.

Bought this battery as an additional battery for my power screw driver that I have been using for over 10 years. My original battery is still running strong, but it’s good to have a spare. These batteries are awesome.
