Re: No Optima 6 volt batteries to be found

If you still have the instructions for your battery it will advise to connect the battery to another fully charged battery and let sit. If the voltage comes back up charge normally. I used this method to salvage Optima batteries that were dead. I also would leave the two connected and charge as a package.

Optimas don't like fast rates of charging which is why the 6 volt generator systems do pretty well with them. The instructions state that standard battery chargers are not preferred.

We had to use Optimas in dyno cars to reduce explosion risk when redlining motors for hours and hours. The high charging rates killed a lot of them.
