Default Re: Optima battery will only chug to 50%

Don, Go to this web site and follow the instructions. It will charge the
Red Top 6V to 100%. Web site:

If the car it is installed in has Vido electronic guages, there is a constant
drain on the optima battery. I installed a battery cut off switch and use a trickle charger (6V) to keep at 100% charge. Once I see the green light on the trickle charger, I disconnect so I do not cook the battery. Gnolnor
