I suspect the batteries might be as much as 10 years old and still working just fine.

Dear Thermoil…..

I would like to submit a testimonial but before I do I need your help. I have 2 Thermoil batteries in my motorhome. I suspect the batteries might be as much as 10 years old and still working just fine. They both have Thermoil added to the electrolyte.

Here is the code on each battery….RV-104920 and the other battery is RV-105218.

Can you tell me the actual age of these batteries?

Thanks, Bill
