When we picked up our Bighorn in April of 2010, we transferred the pair of Trojan T105's from our SOB to the Bighorn. I have been very happy with these batteries until this last weekend.
We usually drycamp, and as it started getting dark, we turned on a light or two. Within a second, they clicked OFF, along with everything in the unit that was on 12v power, then reset and came back on, another second and the process repeats....
It looks like both batteries (two 6 volt in series) failed, and were only putting out very minimal power. Fortunately we had a generator for backup, but prefer the quietness of battery power.
Once we got home, I put the batteries on a 6 volt charger for about 3 hours each, and it doesn't look like they are going to recharge. Amazing - two weeks ago they seemed fine!
So another thing to add to my checklist before departing: check the battery charge level (while disconnected from any AC)!!
These aren't cheap batteries, around $145 each, or almost $300 for the pair. Trojan states they should last 3-5 years. Three years doesn't seem very long for $300!! (Although I'm guessing we got 4 1/2 out of ours)
Any better recommendations for battery power??? Thanks!
