Looks like I need to replace at least one of two cranking batteries on my boat. Have always used lead acid but it seems like I’m always replacing one or both. Decided to switch to AGM. Their cost is very high now … $400 + for one Optim which means over $800 for two batteries.
Thinking of buying just one and running it together with one lead acid. For those of you who have more practical experience on batteries than I, would this cause any problems with alternator, etc? Also considering buying two automotive rated AGMs at 750 cranking amps in lieu of the 1000 recommended. With both batteries in parallel I don’t see a problem doing that.
Can anyone comment?
