I bought these single batt maintainers abt 8 years ago from Walmart. They have worked flawlessly on my Interstate marine Batts. On season 6 this year. https://cimg1.ibsrv.net/gimg/www.off...394d0ddbce.jpg Yup. It really is a cool little unit, even if cheap. It’s lightweight, so we just keep it on the boat, but it’s not mounted. It’s just where we are with the boat. When we take the boat to the Cumberland, we have to option of booking it up if we need to, and don’t have to keep it in mind when prepping to leave. I’m really thinking about taking UnderPsi up on his. Thanks. Brad. |
I've had meh luck with the small, under 2 amp trickle chargers on larger batteries...they seem to be fine on smaller batteries like what is in my Sea Doos, lawnmowers, and motorcycles...so I went with this NOCO 10 amp dual bank charger, it works much better with the AGM batteries in the boat. There was one time last summer that, after a long day of listening to the stereo whilst coved out, that the 'house' battery didn't charge up overnight...to the point I though the less-than-2 year old battery was bad. Had some bad weather move in that kept the boat in the slip for another day, on the charger and voila', it came back fully to life. Weird.

^^^^My experience too with 2amp and under chargers for smaller motorsports batteries and 10-20amp chargers for car/boat/etc batteries. My experience includes many hundreds of batteries probably. Disclaimer: Your experience may differ ^^^^^

Guys,
So, after having both batteries on a standard charger overnight, both are showing 13v+, and back on the tender they both show 14v+. I think both batteries are OK, as is the tender, and that the predictions of the tender just not kicking in due to low voltage are correct. I am falling in line with the lack of warm fuzzy over the tender, though, so I'm going to make that change, but keeping the tender in use until that change is implimented. Thanks. Brad. |

I think we’re good. i did take UnderPsi up on his offer for his charger, though. Thanks. Brad. |

Went thru a bunch of Diehard onboard chargers on my prev boat. Couldn't hardly get thru a season without one dying. Love that NOCO. They have a great reputation. That's what I would install if I went with an onboard solution. |
