I have read many complaints on ESS and AUX battery I removed mine today,. I was charging at 14.4 to 14.9 volts regularly and on the battery highlighted do not charge over 14.4 volts. My ESS would rarely work and called for service often. I read about people using jumpers at fuse block and installing dual battery trays but i didnt want the expense. Lastly the isea of having a battery short out my other battery not thrilled and the battery life of AUX battery is 2 years from what I understand.
I purchased new battery after removing AUX battery and hooked up positive AUX battery cable to positive terminal and now I charge at 12.9 to 13.2 volts and I can jump start at any time should I need to and peace of mind any problems with battery are visible my stock ones were clearly seeping acid out by terminals. I got the Idea from a YOUTUBE vid on the genesis battery tray install. OOPS forgot another thing on ESS battery voltage dropped quickly into the 11.9 volts sometimes I would wonder if it would restart. Voltage no longer drops stop start works sometimes but when it does voltage doesn't drop anymore, I feel it was a great alternative to buying 600.00 DOLLAR BATTERY TRAY AND 2 MORE BATTERIES . Any questions or concerns please feel free to critique also if you have any questions on access or tricks to get to AUX battery or re assembly I would be happy to answer.
