Battery Questions
 

I have a Maxum 2400 that has an unusual battery set up. I have 2 starting
batts on a 1-2-both-off switch, and then there are 2 deep cycle batts
connected to a power inverter in the cabin. I have learned that this is a
"poor mans gen set" set up. All batts were new last year, but now the 2
deep cycles are dead, showing 12.5 volts. What i cant figure out is how
they were to be recharged in the first place. They are connected in series
to each other with NO other connections to the engine/charger area. THe
starter batts both are connected to the battery recharger and have little
orange wires from the charger to the pos terminals. So my question is How
do I figure out how these batteries were to be recharged, do you think they
are dead since they have sat since the winter w/o a charge (I was just
assuming they were being charged by something, and we dont use the inverter
ever) We get near 14 volts when running, and the starter batts seem in very
good condition. Any help is apperciated!

Not sure what you mean "dead, showing 12.5 volts". If they're not being
charged, that's a reasonable resting voltage. Top 'em off with a shore
charger, they should be fine. If you're not using them for anything, I'd
get 'em out of my boat to save the weight.

Could it be that a previous owner simply recharged them from shore power
using a charger? It's common practice for trolling motor batteries.

These are 2 battery faq sites I use alot:
