Went with an Odessey group 34 battery AGM. Same size as my old one plus it has a full replacement warranty for 48 months. Less expensive than what I paid for the other one 2 years ago, and a better warranty.

Good call, Terry. I use Deka AGMs and they are on year 6, but you can't beat a 4 year replacement warranty. Who did you get them through?

My semi local "Batteries Plus" ;)

You fried that battery with the battery tender. DO NOT use the tender on your new AGM batteries because you will fry them too. Get yourself a good quality proper charger to handle AGM's.

Another vote for deka here.

Another Vote for Deka AGM (Actually mine are West Marine SeaMate) or something like that. I was told by a friend that works for Deka that they were made for West Marine by Deka. She also told me that Deka gives West Marine a good deal because the owners of Deka love boating, etc and are tight with the West Marine guy's..

I bought mine in 2007, but really started using them in 2008 (Group 31 AGM). I can start my Diesel with either battery and they are still going strong. I am not looking forward to replacing them, I paid 150.00 each with my Port Supply card in 2007, now they are close to double that now. I do recommend a good on board charger that is Made for AGM, I think that is the main reason the batteries have lasted this long. Mine is a ProMariner Pro Sport. The first one lasted just over a year, then I sent it in and they replaced it with a newer, improved model at a small up charge. This one is going on 4 years. I plug it in the night before a trip.

I buy the Sears Platinum when they go on sale. The 31 size has the same specs as the Odessey, same size, case, ratings. Some say that they are not the same so I dunno, but I've had good luck with them. I wanted AGM because they are in the console and I was mainly concerned with shock loads. They charge up real fast which is nice also. I've also read, they like to be charged at 40 amps or more to make them last. My Yamaha F115 doesn't quite make that but so far so good. My Suzuki 225 EFI didn't make 40 amps either but when I sold the boat, both Sears Platinums were doing well after 2+ years.

Is this true :confused:
