The battery for my Humminbird ICE-35 flasher seems to be giving out. After just a few hours of operation, the unit starts to freak out but when I plug the battery back in and recharge it, it works fine (whew!).  This has occurred twice.  Anyway, should I specifically order a humminbird battery (at WHATEVER cost they impose) or are there other batteries which will work as good or better?  Is the humminbird battery a deep cycle battery?  (I realize the question is someone esoteric but thought maybe somebody might know).

 

Batteries Plus sells the same size 7ah battery from Duracell for $37.  That’s the one I’d buy.

Thanks! I believe I'll do just that!

 

I might plug this battery in one-more-time and see how long it takes (under controlled conditions) before it gives out.  I've always kept a charge on the battery and only use it 3 or 4 times a year (if I'm lucky) .  Sometimes I'll use it on my little Bass Raider when I'm looking for crappie in the local gravel pit.  But it isn't used often and to have it wear out so soon....

There's a ton of brands of smaller AGM batteries out there.  I use a generic one I got from Radio Shack for $20.  It's around 5 years old now and still works.
