Boat batteries

[barling]

I note the six new batteries on my boat are Series 31 AGM's with 110ah made by Universal. 4 are house and one each for thrusters and the engine. What limitations will they give me as I thought 110ah is low? How long should I expect them to last, given I don't do anything to damage them?

You have great batteries if you don't abuse them. Ours are labelled Universal but Kinetic seems to be the brand name on the Universal site these days. Spec. sheet here http://files.upgi.com:8086/UPGFileServi ... heet/40603

If the four house are connected in parallel then you have 440ah. Using the 59% rule 220 useful ah.
