|Old Battery Installation|
When tested, the front battery had two completely failed cells. It would have killed the other battery in short order. As it is, the other battery's life span has been severely shortened. The result of all this terror? Time to buy new batteries. I was hoping to put that off until Lithium Phosphate (LiFePO3) were ready for prime time or at least reasonably priced. They are still at least $1500 or more per battery for the ones I want. So, for now, I sought out and found 2 slightly larger Trojan Batteries. My battery drawer is quite small, but was originally intended to fit 3 Group 24 Batteries. One for the engine start, and two for the "house." I had 2 Trojan 27TMX's in there.
Trik-L-Start battery maintainer and a separate switch so I can completely isolate it from the house system manually.The house batteries were about 7+ Years old. Thankfully I managed to beat their "normal" life by treating them well. Since the battery box/drawer is about 18"x14"x10" I could get two group 31 batteries in there with a bit of room to spare. I selected the Trojan SCS225. It would fit and would give me an additional 25 Ah to play with. (130 vs 105 each battery)
This could have gone the other way. I could have come home to an charred wreck of an RV. I have no one to blame but myself. Batteries need to be monitored and checked. If you are used to seeing a particular set of readings and they change for some inexplicable reason (you didn't change/add/modify anything) be wary!! It could end in disaster. Next week, I will do some real world testing on capacity, but the manufacturer states I will not get full capacity before I hit 10 discharge/charge cycles. We'll have to see.
