I have been reading a lot about batteries for my travel trailer.
After much research I have focused in on AGM type deep cell units.
Amazon has an Excide brand AGM with a 100 AH rating for a little over $200.
comes with a two year free replacement warranty.
Lithium batteries are also worth considering but availability and cost are a concern. I want something that will last.
Last year I purchased a group 27 size deep cell standard liquid acid battery
made by interstate. It came with a one year replacement warranty. It discharged to about zero on two occasions when parked without power and no real load...
not good...I was so upset that I returned it at the end of camping season last November and insisted on a full refund not a replacement. Since I purchased it at a Walmart the refund was not a problem.
I plan on having my trailer's electrical
system checked to make sure that the rapid discharge of last year's battery
was not caused by my converter or some other system failure. I will do this before I buy another battery.
First question is what battery to buy...right now I am focused on an AGM type.
Second question is am I missing anything else that could cause battery failure.
My goal is to buy the right battery with a long life expectancy and not spend a fortune.
Any and all advise appreciated. Thank You.
