I have two 12volt batteries on my sailboat. They are connected through a three position switch which can connect battery A , battery B or both to the distribution panel. When I got the boat there were two trickle/maintenance chargers with one on each battery. One of them has died. My question is, can I put the switch in the "both" position which will put the two batteries in parallel and charge them with one charger? My concern is that if one battery is nearly dead and I parallel it with a possibly fully charged battery then the battery and or the charger may get damaged. Thanks for any replies.
