Kerbl Digital Battery Tester 6-20 V for Fence Energisers

Digital Battery Tester 6-20 V – reliable battery checks for fence energisers

The digital battery tester lets you check the batteries of your electric fence energiser in seconds. It shows whether your fence battery still holds enough charge, helping you avoid weak fence voltage and keep livestock safely contained.

The tester measures both the open circuit voltage and the voltage under load, revealing hidden charging issues that a simple glance at the battery can't show. Since it needs no internal battery of its own, it's always ready to use in the barn or out on pasture. After a short time, the tester switches off automatically to protect the battery being tested.
