Good morning. My coach (still waiting for that first real trip!) decided to die. The 10 year old starting battery (6/07!) discharged over a period of 2 weeks of no running and trying to troubleshoot the Onan (my bad!). I put her on the trickle charger but it will not take a full charge (NoCo Genius 1100 Charger - maintenance charger that works on everything else). Best I can get is up to the 75% mark on the LED's (100% flashing but never going solid). Checked the battery on the multimeter and came up with 11.8 V. Which from what I am reading is 25% charge at BEST or completely DOA (depending on whose page you read). That is after 4 days on the charger. Got just enough juice to by-pass & test the temperature sending unit (yes, it is dead & I have a replacement). But won't even consider trying to turn over (just growls at me! Briefly!). So it can RIP I think. I killed it.

I have a new Interstate AGM house battery in the generator bay that is holding a nice 12.9 V. I am considering dropping that in as my starter battery and getting 2 6V golf cart batteries for the house. The Interstate is a top post battery - my cables are side mount. Anyone have any experience with the adapters for side to top post cables? Canadian Tire here has some that are short cables - helps to eliminate the possibility of insufficient cable length when you add on the adapter.

There is also a disconnect lever switch attached to the positive post - (should be on the negative post?). I plan to try to check to see if there is some phantom power drain (once I have enough power to drain!) in case that is the reason that switch was installed.

Opinions on the move Interstate to starter and add 2 golf carts? Will be pricier than just getting a new starter battery but a good new battery will be about $150+ anyway. So I am not averse to dropping another $100+ for the golf cart batteries if that is worth it. And also - opinions on the adapter scenario.
