Best Batteries?
Looking to add a battery and replace the 2 in my boat. Guy who put in my stereo system says Optimas are best but have to use a red top, the other ones not as good. I have heard some so-so things on Optimas. What is everyone having luck with. Going to have 2 batt. to run stereo etc while parked, one for starting/backup.

One 31 series will easily take the place of two Optimas.

I am on my 4th season on Optima Yellow Tops. I have 2 and run the stereo a lot. I am very surprised they have lasted this long. I was going to swap them this year but they charged all the way up so I decided to use them. Plus I have US tow boat service so I figure the worst is I have to wait for a jump. One thing I have been doing is keeping my Perko Switch on ALL . I know people say use one for the stereo and one for starting but this works for me.. Also make sure you have a charger that can be set to charge AGM batteries.. I think that is where some people are having trouble, Charging with the wrong charger.. I am by no means a battery expert but I am on my 4th season on the batteries so i must be doing something right.

was looking today, battery supplier says not to use AGM/gel batteries unless you upgrade you charging system, most boats wont charge them properly, anyone heard his?

I have used Interstate in my boats for years. Make sure your audio amps have low voltage protection so you don't kill them as the volts/amps drop throughout the day.

I switched to AGM batteries (Seavolt from West Marine) after breaking a couple of Exides wave hopping. The AGMs charge fine using the boat's charging system or my deep cycle charger.

I run 2 blue top optimas with around 2000 watt stereo. Run the stereo on full capacity (2 subs and 6 components) for 8 hours with no problem. I always hook the batteries up to an AGM maintainer when I get home to make sure the dancing doesn't end the next day I have one battery wired to start the motors and one battery wired to the amps and accessories. Worst case scenario this way is that I have to drive back with no music BUT atleast my motors start.
