looking for a recommendation for a battery charger for a GW Fisherman 215, she will be on dry stack.
Thank you,
Thank you,

I have heard a lot of positive endorsements for the NOCO line. There also though have been reports of chargers 'detecting' current issues and switching off. The charger has to be manually reset to come back on-line. The issue seems to be related by increased current draw while the charger is in maintenance mode. Some have reported that something as simple as a bilge pump kicking in when the boat is at the slip can fool the charger ino thinking that there is an unusual and unexpected load which causes the charger to think there is a fault.
Has anyone had a similar issue?

It's a little bit of a Chevy vs Ford thing... but I'd also go with Pro Mariner - the Pro Nautic series, to be exact. These have been standard issue in Sea Rays (and others) for decades with an excellent track record and a great charging profile. They're designed specifically for the marine environment. Regarding the track record... to better clarify... over 30+ years I've personally had a few of these and also see them in the many, many customer's boats we see in the shop.
I’ve been very satisfied using Noco genius genpro marine chargers in my previous 27 sailfish with 4 agm batteries, and just installed a dual bank in my new 2025 freedom 235.
I went with 10amp per bank units because some agm batteries specifications like odyssey extreme agm group 27 requires 8.8amps min to properly charge.
When I was shopping and inspecting the 235 many times pre purchase last fall, the batteries were dead on a couple of occasions. When I took delivery of the new 235 after winter storage, I suspect the Marina did nothing to properly maintain them over the winter, and just put a surface charge pre delivery. They were at 12.5-12.6. After letting the Noco run in recondition mode till completion for a week, they’ve been holding a steady state voltage of 12.7-12.8. The 235’s factory batteries are deka heavy duty agm.
I’ve never experienced the false detection issue previously mentioned in this thread. Noting the sailfish had a rule 2000 automatic bilge pump with electrical water sensor cycling in the aft bilge, an automatic float bilge pump in the fwd bilge which switched on more often when moored at the dock, and the mercury engine’s clean power leads were directly connected to the battery and therefore always powering their ECUs.
Not applicable for me, but these Noco multi bank chargers are completely independent per bank regarding battery type selection and respective charging rate profile, so one could be using a mix of battery types, such as a unique lithium battery for a trolling motor.

My single bank Noco occasionally lock up (red light on front) when I'm running bait pumps and charging overnight. This battery also handles my bow thruster - which isn't being used overnight. It's likely a combination of the thruster drawing the battery down and the pumps for the baitwells when I get back to the dock. If I switch the baiitwells to the house battery it never happens. Probably drawing too much current initially. Power off to reset and it's fine.
