Chief Delphi - Multiple Batteries from one charger

1. Never try to charge two batteries from the same charger. Batteries have this bad habit of supplying current to each other (when connected in parallel) until they discharge and/or short.

4. DougHogg, another engineer also found this Battery Minder charger but we both felt that the claims were too far fetched to be real. I am still waiting on a better test, but we chose not to buy one. "If it sounds to good to be true, it probably is."

Al, thank you for your post on batteries.

On point #1, can you expand on that. I have been charging our batteries in parallel for a year, and haven't personally observed a problem. I am not an engineer, but I am trying to understand how the problem you mentioned could occur. If both batteries have some charge, why wouldn't they flow from the most charged to the least until they balanced each other and then stop flowing (like a full bucket of water flowing through a hose into a partially full bucket until they were at the same level.)

On point #4, I did a search on Google for "BatteryMINDer" and "Review" and found positive feedback on the BatteryMINDer, but no scientific testing from an independent source. I will keep my open for more info.
