ok... car is my 90 4runner.

doesnt get driven that much anymore.

battery is a new 6 month old red top optima.

lately, i charge the battery on a 12 amp charger to get it ready to run.

but recent issue is that after a drive with stereo system going, like last nite, i cant even start the thing after getting gas.

only a jump start would get me going.

1. i know the recent reputation of optimas arent like they used to.

2. no wacky lights from dash saying bad charging. all lights do normal startup flashing.

3. using a simple cheapie device connected to cig lighter says charging is 13.5v and above during driving.


what am i missing?
