Dual Batteries
If adding a 2nd battery does it need to be identical to the 1st battery?

they do not have to be identical .
IT IS BEST to be identical .
Before you flame me I was an industrial electrician before becoming a lumber company owner .
it is agreed on this forum that 2 6 volt batteries in series is the best solution .
I make the argument that AGM batteries , typically 12 volt in parallel are the next best solution .
I further make the argument that an exide edge agm battery is compatible in charge rate as a conventional battery .
I ran a conventional battery in parallel with my new upgrade edge AGM battery until I got an identical AGM battery to be its mate .
I had no issues .
I paid $ 140 each for my exide edge agm batteries at BiMart .
They charge faster , do not corrode , have a 4 year guaranty , typically last 7 to 11 years , and are made in the USA .
Over time I converted to edge AGM in my TT , Boat , duramax , Porsche , and Mercedes ( agm standard , I just replaced with edge AGM group 49 ).
