HIDs killed my stereo?

[Jonilink]

it was just a battery/alt tester from auto zone not sure if it was over 14 volts that's what he said. but the battery is good no starting issues

no not the cells, but most are sealed these days so cant test the bat cells.

the old load tester that you clamp onto the battery will tell you the volts, your cars not going to like running over 14 volts. multimeter works too
