Acountdeleted Posted November 29, 2015 Report Share Posted November 29, 2015 Started unpacking my ice fishing stuff today in (very premature) anticipation of the upcoming season. I was using my 12v battery from my flasher over the summer with my hummingbird fish finder. I could have swore they both used the same battery (worked great with my hummingbird) but now I plug it into my charger and it says it's fully charged. The charger. Have is just one of those small ones that have a red, green, and yellow light. Regardless of what I do, the light stays green saying that battery is charged. Yet when I plug it in to the flasher or fish finder nothing works. I get the feeling I probably fried it and need a new one, but I'm open to suggestions as I can't really do any more damage. (Saving some time, yes I checked, the flasher and hummingbird cords are all attached and in good condition. No I don't have another battery to test everything with).

ecmilley Posted November 29, 2015 Report Share Posted November 29, 2015 First check then open circuit voltage of the battery. Try the charger on sething else. but those small betterys only $25-30 anyway Link to comment Share on other sites More sharing options...
misfish Posted November 29, 2015 Report Share Posted November 29, 2015 Your battery is pouched. I have the proper charger and have had a few batterys do the same. NO POWER. Link to comment Share on other sites More sharing options...
SirCranksalot Posted November 30, 2015 Report Share Posted November 30, 2015 Have you tried leaving it hooked up to the charger regardless of what it says. Maybe the charger is giving you a false indication. Do you have a reg car batt charger with a 2 amp setting? Link to comment Share on other sites More sharing options...
Acountdeleted Posted November 30, 2015 Author Report Share Posted November 30, 2015 I do. I plugged it in overnight. If it doesn't charge I'll try the trickle charge tonight. Link to comment Share on other sites More sharing options...
