Charging voltage for T-105s
Continuing my quest to learn everything I can about batteries and charging... Moved on from the group 24 Interstate, may mess with it more later. Also put the hydrometer with the floating balls whe...

The shumacher chargers seem to have the highest voltage of them all,....over 16 volts on my larger one, and well over 15 volts on the smallest maintainer ones.
I try to avoid using the big 16v one, as no battery needs over 15 volts.
If you want long battery life, and very little water consumption, connect to a PD converter, and forget it.
If you got suckered into the hi voltage boxes, and believing you have to babysit and sleep w/ your batteries, good luck.
13 yrs out of a pair of batteries ??? Very possible, but you can bet they have never been fried w/ hi voltage boxes that were never designed to be battery chargers.
I'm sure the best way to get long life out of a set of batteries is to follow the manufacturer specifications. Maybe the PD would do that (although I don't think it gets to 14.8 as required by Trojan) but it doesn't matter anyway since my RV gets stored with no hookups. For now I will be removing them after a trip and charging them at home, it's really the only option. The only question is what, Schumacher, Meanwell etc. In the end, I will use whatever method comes as close as possible to Trojan's specs.
