wet & gel Batterys

G/Day all ,,
Chasing some info from all clever travellers,, can I hook a wet deep cycle battery (115ah) ,up with two gel type deep cycle battery's (100ah)
Thanks Flatty

Hello Flatty,

yes, you can.

Select the charging algorithm for gels (i.e. boost 14.4V, float 13.6V) and the wet one will be in a happy threesome with them.

Expect the wet cell to lose capacity at a faster rate than the gels as time passes.
That's because wet cells only give you a limited number of cycles (depending on average DOD) compared to gels.

Best regards, Peter

Flatty,

Yes, But..... Not ideal because the two types require different charging voltages. You won't get 100% storage out of them if you simply parallel them all. That said of course, there are lots of gel and AGM batteries being charged by the alternator that's also charging the wet starting battery, exactly the situation you're talking about.

Unless the charging instructions on the side of the batteries suggest very different voltages, I'd parallel them and every so often disconnect them and give each a full charge from a charger.

Flatty,

While I was writing the above, Peter has responded and said the same thing only better!

Cheers
