Marine deep cycle batteries
I am planning on going on a fishing trip, my bass boat has not been out since i restored everything on it three-four years ago. As such, the deep cycle marine battery is at least that old and had 1.6v on it last night when i checked. I put it on the charger just for fun. Is it going to take a charge or will it have to get replaced? Its a sealed Delco Voyager, with the little sight glass.

It may take a charge but just not hold it as long, or just take a surface charge where it shows 12-13 volts but has insufficient cranking amps. I've rechargerd old batteries that worked well for a while if I used the vehicle every day or so, but would go dead after sitting for for a week or more. All I can say is it's worth a try but don't expect startling results.

hey i work on batteries for a living. if a battery like that hasn't been charged for that amount of time its dead for sure. even if you could force a 12V charge in it (which is extremely dangerous) it wouldn't hold it for very long.
now that i think of it, a 12V jar with that little amount of voltage could be a safety hazard, so take it to the nearest place that recycles batteries to be safe.

My guess is that it's done for - but, if it charges up and holds 11.5 -12 volts after charging, wire an old sealed beam headlight to it - see how long it will stay on. If it doesn't stay on long, dump it.

It was such a good battery! One we will always remember! Why,3-4 years ago, a three hour tour on the lake was nothing, it's a shame he holed up since then. The dust bunnies sucked the life out of ole deep!
May "ole deep" rest in peace, at the recycle heaven!
