Battery posts are all over the board here and after reading a ton of them I didn't really know where to post, so here's a new battery thread.
I just replaced my 4 house batteries, had mixed age and brand in place earlier and they don't hold a good charge. This is a new coach to me also so the decision to replace all four was a no brainer as I don't want any headaches down the road.
I purchased 4 Interstate GC2 XHD 232Ahr 6 volt batteries (vs Trojan T-105) I get a good discount at Interstate, so the GC2 XHDs cost me $109 each.
The UT2400s he had in stock had a terminal that wasn't the best config for my app, so I passed on those. (@$15 more ea) Asked the Interstate rep where these batteries are made. Both the GC2s and the UT2400 are made in Mexico. Interstate has many of there batteries now made in Mexico vs China sourced, There has been quality issues from China but Interstate still has and does source product made in China but less today than a few years ago.
I Re-finished the battery tray. Cleaned it up first, then used Rustoleum's rust conversion paint on the rusty tray and finished up with flat black.
I used a plastic coat spray on the terminals and wire lugs. I haven't see this stuff used for this application before. I'll post down the road and give an update to see if this was a good idea or not. I did take pics of the install, not sure where to post them.
