Hey John, are you keeping the lights on ? of course they drain your battery. Did you measure the current they draw ? What kind of LED's did you use ? What do you mean with 11 ? 11 Volts ? Does ist still crank then ? Elvis > Question: > My new Optima battery drains only when the rear engine compartment is open. Goes below 11 in two days. I have numerous lights (7)in the engine bay, however they are all LEDS. I have isolated it to that point but unable to figure where else to look.--- Or does the amount of Leds matter? Is that causing my problem? > Any help would be appreciated much.
