The charger then needs a manual override to push current into the battery and wake it up. I learned this the hard way with a battery that sat all winter. Once I pressed … Read more

Some chargers skip an LCD screen to cut cost, reduce failure points, and rely on simple LED lights instead. A few small indicator lights show charging stages without the bulk of a display.
