Bad A$$.Love

The charger worked as it should for the first couple of charges, but then all of a sudden it would get stuck in 'charging' mode indefinitely no matter how long the charger was left connected to various batteries, never advancing to maintenance mode on the LCD display.

Depressing as it is a sealed battery that shouldn’t vent and prior to now has never had any issues

After a couple failed battery charger purchases, the Optima performance maintainer works as it should
