Battery Issues

Battery History: I have 4 (6V)Interstate batteries that are 6 years old and maintained with Xantrex GS Series Inverter Charger and ProFill watering setup on my 2000 HR Endeavor gasser. I typically stay plugged in year round and keep the water level up about once a month. I have never really used this set up for any dry camping more than 3-4 days once a year and its not really dry camping, really only using the batteries to keep everything running when not running the generator.

I am now having low battery issues. When plugged in or running the generator I am getting about 13.6 volts at the batteries consistently
but it drops to about 10 volts within and hour or two after no genny or shore power. I still have enough DC voltage to run the water pump, fridge during the night.

I suspect I have shortened their life by not ever really charging/discharging them on a regular basis.

My Xantrex main unit and the RC-6 remote panel indicators show "low battery".

Planning to replace all 4 and change my maintenance routine going forward.

Any thought or opinions?
  • Your house batteries are toast....Replace with GC2 batteries (interstate) and you can get from Costco..82 bucks a piece is your cheapest way out..OR, you can go with AGM batteries and they will cost more (way more) but no more battery level issues....check out the Trojan site for AGM batteries...
  • Yes. Batteries are old. Car battery won't last that last long. Neither do house batteries.
