Answer This Question

A:  The battery is 6/16" inches in diameter. So if you measured it correctly this battery is too small. I would take your battery to Home Depot and get a staff person to help you get the correct battery.

by|Jul 27, 2021

A:  3/8" as shown in the picture.

The battery in my after-market remote control for my truck finally died. A quick jaunt to Home Depot, grabbed the 2-pack, replacement, and I have a working remote again with a spare for next time.
