Love this small screwdriver. So lightweight and easy to use

It’s a good battery — lasts a long time, years, can’t even count ’em it’s been that long.

These batteries were purchased to replace the original batteries that came with the Ryobi TEK4 tool that is about 4 years old. They are the only batteries that can be used with these Ryobi tools. The TEK tools are convenient for smaller jobs and the batteries last a long time but are getting harder to find. Hope The Home Depot continues carrying the Ryobi products.

Fit perfectly. Charged quickly. I used it in my Ryobi cordless screw driver and it worked well during the 20 min job with good power still remaining!

I bought this to have a backup for my Ryobi drill/screwdriver, the batteries last for a long time and have plenty of power for my needs.

Battery supply provides ample power for little jobs that do not require the use of a bigger tool.

I needed a battery really quickly for my inspection camera in order to finish a job. The battery was in stock and had a charge on it so I was able to complete the job right away.

Glad to still find these batteries for an older design drill.

I’m happy with the Tek 4 system. The cordless screwdriver makes my DIY project so much easier. Having extra batteries helps me to not have to worry about running out of power in the middle of a job and they domlast pretty long.

Bought it for my daughter-in-law so she would have two batteries for assembling kitchen cabinets. The old battery is many years old and is finally not holding a full charge but is still usable.

Wish I could comment but I was using on a job for about 15 minutes and dropped it down a hole of no return but it seemed to be the ticket I was looking for

Could be good change the charger led color. When charge it’s green, I thought at the first charge, green mean the battery is fully charged. Nut every kind of brand chargers have other system, I thing under charge would be good red, when fully charged green. But this is not the battery review… Battery is perfect.
