ok, im looking for a battery to run my fishfinder. first thing, I dont want a lot of weight, but what is small enough, yet, strong enough just to run my fishfinder? i dont have a whole lot to work with as funds go.

U mite be able to find one that has been reconditioned, or at least one that has good cell readings with a hydrometer & will take a good slow charge..........
GraphiteZen said:It's all about the milliamp per hour (mAh) rating, you will need something over 30 or so. When I had a fishfinder I ran it on a batt that was smaller than a 6 pack but ran for days, I believe this was a 35 mAh. However, I bought it new and it was spendy. If by chance you know someone who installs home or business alarm systems they might have some laying around. I got a spare from my uncle that way.
Somewhere on the finder or in the manual there will be a reference to milliamps.
