Dont know anyone running a gel in a boat. By chance do you mean AGM? I like both for different reasons. Cant beat the $$$ to Ah ratio of a good quality LAWC but for a large house bank thats going to see repeated deep cycles, AGM's will last longer. Also consider pairs of 6V GC's for a house bank. just need a good maintenance regiment.

I installed 2 6v batts for the stereo bank and i'm extremely impressed with them. I've played them for entire weekends and never once had any issues. Of course I shore charge them when home and make sure that they are full of water but so far heads and tails better than my single 12v bank was.

Sorry for hijacking, but this is kind of along the same lines... those with a dual battery setup, do you have a starting battery and a deep cycle, or two starting batteries, or two dual purpose? My ss230 came with two starting batteries and number one is already worn out in less than 2 years. Wondering if I should switch to a deep cycle to run everything else and moving the other starting battery to be primarily used for starting now. Any thoughts?

@ Sallen,

 

How is that #1 battery used? Is it your main cranking or a dedicated house battery? Is your dual bank setup using a traditional 1/2/BOTH/Off switch or the dual circuit plus switch with a VSR? Do you have a shore charger or access to A/C so one could be used?

Battery 1 (the one that doesn't hold a charge now) was the main cranking battery. Battery 2 (also a starting battery) was being used as a house battery. The switch is off/1/both. I am pretty green with electrical so not sure what the VSR is? I trailer my boat is it goes in the garage after every use and I frequently (though not always) remember to put it on a trickle charge afterward.

Its odd for a marine cranking battery that was used as a cranking battery, to reach its end of life in 2 seasons. What type of charger are you using?

Battery Tender trickle charge. And yeah, very odd. But should I replace it with another cranking battery or move the #2 battery to that position and then put in a deep cycle as the house battery?

For a switch and voltage sensing relay setup I like to have a cranking battery for starting and a deep cycle for the house side. As to moving the existing cranking from the #2 house side to the #1 cranking side is a tough call without knowing the condition of that battery. If your trickle charger is not a multistage smart charger then I would be careful with how long its left on to charge.

Sounds like to be on the safe side that I might want to consider 2 new batteries? Cranking and deep cycle? And just get it over with? FWIW that Battery Tender is a smart charger and doesn't over charge. It switches to maintenance mode when the battery is fully charged.
