How much battery power / capacity
It looks like I will VERY soon need to replace four of my Trojan T-105 6 Volt golf cart type batteries that are 8 yeras old and do not keep the charge any more. 13.4V to 12.3V with all lights and stereo running for two hours? I can not see the capacity rating but according to salesperson new Trojan T-105 has 225 AmpH capacity.
I do have to confess that although batteries are 8 years old i did neglect them for a while and last October found them drying out having to fill in almosta quart of distill water in each which might have caused the drop in performance.
I use my boat mainly for daysail and sometime for a long weekend, using stereo, lights and nav instruments. No big consumers onboard. What sort of capacity you would recommend?
