Thread: Duracell TM Batteries

First question is your charger compatable with AGM? If so I would guess that they would give you a little more run time and longevity is pretty good. 5 years out of your interstates using them like you do is pretty impressive and sounds like you do a good job of maintaining them. Is weight a issue. If not rather than high priced AGM I would go with golf cart batteries. Your charger red lines because your batteries are pretty much run down at the end of your trip and charger is a lower amp out put so it goes to max charge and then will start to back off as the surface charge starts to build.

Thanks for the response Cray
My charger is an older schauer 2-10-50 amp start unit that I got at a garage sale prolly 25 years ago or more so I don't know if it is AGM compatible
Now that I've opened my big mouth, the interstates will prolly be shot when my boat comes out of storage!!
Weight is sort of an issue, so is size my boat is a 14.5 1958 Alumacraft Queen Marie the bank of batteries is up in the bow , along with the charger because they are so far forward its really hard to get up under there to hook them up to the charger plus as soon as I get home I plug them in until I leave for the next adventure on the water
I've been thinking of putting a flexible solar panel on the bow because I abuse the batteries so bad on overnights and 3 day trips on the river.... But the 58 is mostly restored and looks are kind of important
Sorry I kinda got way off topic

I would look hard at the AGM and I would for the sake of weight and size take a real hard look at the NOCO Genius onboard chargers. All digital, AGM compatable, all digital. They are expensive ( in line with Minkota and cheaper than Dual Pro ) hook to batteries, mount and forget it. Just plug in when you get home, unplug and go to lake. The way you use boat you need at least a 10 amp charger. AGM require a higher output voltage than most chargers are regulated for on lead acid batteries. Your charger would charge them but probably never really top them off thus over time shorten the life of the battery.
