Roy Posted June 24, 2011 Report Share Posted June 24, 2011 Sure they make them but a 12v 100ah group 31 is $1500. and all you're really saving is weight. Of course you can always cut back to a 40ah for a measly $900. Link to comment Share on other sites More sharing options...
irishfield Posted June 24, 2011 Report Share Posted June 24, 2011 (edited) Exactly Roy... I know of these batteries from aircraft guys trying to save weight and ending up with a burning hull. I'll stick with lead and acid.. I generally get 10 years out of a battery = $13 / year ! Edited June 24, 2011 by irishfield Link to comment Share on other sites More sharing options...

irishfield Posted June 24, 2011 Report Share Posted June 24, 2011 I need more than that. All batteries have the potencial to start fires or mallfunction. question still stands. do they make lithium batteries for marine use? BTW... most normal batteries just have the potential to explode.. usually when frozen and boosted. Lithium Ion actually catch on fire. Link to comment Share on other sites More sharing options...
fish_fishburn Posted June 24, 2011 Report Share Posted June 24, 2011 Total Battery sells a product that restores tired batteries and you will get another year or two out of them. I can't remember the name but it is a small bottle of pink liquid that you put in each cell and then recharge. It's about 15 bucks and it really does work. Check it out, I use it and my batteries last about 7 yrs on average. Link to comment Share on other sites More sharing options...
lew Posted June 24, 2011 Report Share Posted June 24, 2011 For cranking batteries, be sure to shut off your boats master switch at the end of the day, cause if you don't, BOTH sonar units AND the GPS unit will continue running all night, and when you head down to the boat in the morning to go fishing again, your battery will be deader than dead....just like mine was at Lakair last Sunday Link to comment Share on other sites More sharing options...

And don't forget to unplug your trolling motor. I've heard of some horror stories with TMs being left plugged in. Link to comment Share on other sites More sharing options...

NAW Posted June 24, 2011 Author Report Share Posted June 24, 2011 I wonder why the guy at total battery didn't suggest that option.. Hmm.. I know.. Now he has my $125 in his pocket. Or, my battery was beyond repair. Link to comment Share on other sites More sharing options...
