I'm needing to purchase a 12 volt battery for my new Lowrance Elite 4 fishfinder gps. That will be the only job the battery will have btw. I'm thinking I won't need a full size car battery. I'd like to not have to deal with the weight. I'd also like to have enough capacity to last a full weekend of fishing.

I've looked at the smaller lawn tractor batteries and they seem to be just right.

I'd appreciate any advice so I only have to do this once!!

Thanks all,

Lee
