I have a Sears Diehard Platinum group 34 as my 2nd battery which I use to run an Engel 35 liter fridge. I use the National Luna split charger to maintain both the starting and accessory batteries.
Suddenly I found my battery pushing 8.5 volts after about 8 hours of running the fridge. I put a charger on the battery and brought it back to 13.5 volts and it dropped back to 12.2 not long after removing the charger.
After running the fridge for another 6 hours, the battery reading is now 11.8 volts and dropping.
The battery is about 5 month old and I had Sears check it. They indicate the battery is fine.
Back ground info: For the last few days, I have been making only short trips around town with the vehicle. In other words; 5 minutes here, 10 minutes there, maybe 15 minutes somewhere else. It could be not enough time to maintain the auxiliary at full charge?
Do you think I have a dying battery or some other issue. I'm concerned about the rapid drop in voltage after a full charge.
Thanks for any help.
