Micronta battery tester repair

old Radio Shack battery tester AKA Enercell

Sometimes these old Radio Shack battery testers can stop working due to the paint rubbing off the spring that puts pressure on each battery.

Once the paint is gone the spring shorts everything out and reads bad battery.

It's easy to fix by taking the back cover off and inserting a piece of electrical tape behind the spring.
