All seven Batteries on our 2000 Tiara 3500 Express with twin Cummins 6BTa's and Westerbeke Generator were replaced in 2019.  The water level has been checked multiple times over the years and they check good.  All are the same batteries.  At 5 years old I'm thinking to replace them all.  Would AGM be a good choice?  Any brand recommendations or just stay with lead acid.

Thanks, Mike

I have a 2004 38 Open and have 3 engine and 3 house size 31 AGMs from Batteries plus. They are Duracell.

I have had them for 4.5 years with zero issues. I actually going to replace the engine batteries in feb just because I am taking it to the exumas and dont want to take any chances with batteries.
