Which Brand Battery Do You Use to Start Your Sailboat Engine ?

So lets keep this short and simple in your replys.

My 7+ year old auto store battery is done and its time for something new for my 20hp Beta.

Please simply reply with what brand/model and style battery you use to start your engine, and if you have an opinion on how it is holding up.

I am looking at a 1000CCA Intersate flooded battery. I know I don't need that many CCA for my liltle engine, but for a few extra bucks I figure it will last a liltle longer.

I use a 1.7lb 4.6Ah lithium nanophosphate starting battery. I can start a big diesel engine but at only 4.6Ah it can't power continuous loads. Mostly for race boats (and race cars), but fun to show off...;-)

Re: Which Brand Battery Do You Use to Start Your Sailboat Engine ?

Deka Group 31 flooded. A bit of overkill for my 4-108.

IMHO, AGMs are overpriced and overkill for starting batteries, and some seem to be prone to catastrophic failure. Flooded batts are more reliable and much less expensive.

I like OceanPlanet's "1.7lb 4.6Ah lithium nanophosphate starting battery". Do you carry that in your pocket?

Btw, also used two of these in series (24V starting circuit) on the IMOCA 60 Mapfre for the Barcelona World Race. Works great.
