As designed the OEM cooling system delivered the following results.
Under L-2 the case temperature peaked at 56F above ambient temp.
Under L-1 (12 amp) the case temperature peaked at 48F above ambient temp.
So charging L-1 only delivered a ~15% decrease in charger temperature rise.
I didn't check the temps at 8 amps L1 since I don't consider it a useful charge rate for our needs. Plus the high percentage of power going to overhead "vampire loads" rubs me the wrong way. Presumably 8 amp L-1 would run some cooler than 12 amp. I wonder though if that matters much though since most components are rated in "Mean TIME between failures". And L-1 runs the unit much longer than L-2 for each recharge?? I'm not sure that most people have the ability to do a lowered amperage L-2 charge but it seems as though the results would be similar to L-1.
