My Remedy :
AGM Batteries
These are the kind that you can mount sideways because they are gel .
AGM construction batteries on my trailer and my truck .
I paid $ 140 each for exide edge AGM batteries at bimart / Oregon .
Do a google " AGM " for the reasons to do AGM .
AGM are maintenance free , do not leak , do not off gas , have faster recharge , will take more abusive deep discharging than conventional battery construction .
My main reason for switching was the acid leakage from my conventional lead acid batteries .
EXIDE EDGE AGM batteries are made in the Carolinas USA as I recall .
