I am replacing two house batteries in my BW 27 and will be using a solar panel charging system. There are several brands of gel deep cycle batteries but which is the better and at the better price?

First of all do NOT use a gel cell battery. The typical charging voltage of outboard motors it too high for a gel cell. Note that an absorbent glass mat (AGM) type battery is ok for use.

Check out Cabelas AGM batteries:

Ditto on the Cabelas AGM. I switched over from the Optima bluetop because the Cabelas are cheaper and more cost effective. I've got two Cat 24 on my Whaler.

Thanks for the input, All the hype with the gels I figured they are the best. The motors I have are 1998 yamahas, I beleive the the motors that have higher charging power are the newer models.

Thanks,

Rob

Why the interest in a gel battery? You can find deep cycle batteries in flooded cell lead-acid and in valve regulated absorbent glass mat. I am curious why you think you need a gel battery?

The best deep-cycle battery is probably a Rolls. They have a seven year warranty and typically last for 10 years.

What is the warranty on the Cabela's AGM cell? Only ONE YEAR?

I know my outboards will not support the charge I need for my four batteries (2 cranking and 2 house), my house batteries are responsible for a lot on the boat. flood lights, Hydroglow, radar, gps, livewell and assorted other lights. My cranking batteries are independent (thru an isolator) but I am installing a solar system to maintain a full charge on the house batteries. I assumed that the gel batteries were the best but a seven year warranty speaks for itself. It's funny that Rolls is located in Nova Scotia because that is where I bought my boat. I looks like a great battery. My batteries and charging system must be second to none. Thanks for the response.
