battery life

[GeoFisher]

Hey, guys im telling you i keep my boat plugged in with the onboard charger the boat is new with new batterys. With the interstate battery im good for about 10 hour maybe 12 if the wind not blowing. My old boat if i used walmart batterys i may make a season out of them. I check the water every month I fish just about every day after work and every weekend im some where fishing a tournament or just fishing. I have never had much luck with batterys. Would love to know what the best is? Opitma are so high but why buy when the batterys in the boat are under warranty.

I fished 30 3-4 day weekends last year, and a few times during the week and have not had too many problems with my current batteries. They are Walmart and I've had them 3 years now.

I check the water EVER TRIP, and make sure they are fully charged as soon as I come off the water. I NEVER let them set 1/2 charged.

If I don't plan on using the boat for a prolonged time, I take them off the charger but make sure I hook them up once a week just to make sure.

I clean and check the connections......and then reclean and check the connections.

Make sure the wire connecting the two batteries is big enough. You might be losing some current there. Also, make sure the wires everywhere else are big enough. Troll constant for 30 minutes, and check the plug where your motor plugs in and the wires in the back. If they are more than a little warm, you might have something loose that is causing you some issues.

Later,

Geo
