Taking a V reading at remote posts?
Facts: my battery reading AT THE REMOTE posts is ~ 12.45-12.54V after sitting for 24 hr (no load ammeter reading, reading at the "bolt" and the remote red access point, not directly off the battery posts).
I'm assuming that the reading at the remote posts is lower than direct but by how much? I've read this 12.45V reading is around 75% charge (came off a 2 hr run yesterday and just sat for 24 hr then took the reading).
Searched here and elsewhere and general observation is replace at 12.4 V or so but this is not definitive.
Battery is original (5 yr old). I always keep it on a BT but this is not always possible is why I ask:
Time for a new one?
