using on board charger in winter

11 posts in this topic

I got a new on board charger last year and did not use it over the winter. My boat is in cold storage in my garage which is not heated. should I leave it plugged in in below freezing temps?

Absolutely, that is what they were designed for. Keeps the batteries from freezing and fully charged.

I usually leave mine plugged in all winter long too. Either that or I bring the batteries in the house and just check and charge them periodically.

Some guys don't like leaving their chargers plugged in all winter long. They leave their batteries in their boat and plug in their charger periodically. But I think most of the chargers are designed so they can be left plugged in all winter long.

I leave mine plugged in all winter too, but be careful that you don't have anything drawing power all winter. My trolling motor got switched on and even though the power was cranked down to zero and the blade never turned it still burned up the trolling motor and batteries. Anything plastic in the trolling motor foot switch or in the motor itself melting including the insulation on the wires. The trolling motor also melted a hole in the tarp we use to cover the boat. So now we make sure the tolling motor is unplugged before we store the boat. I do think that batteries last better if you leave the charger plugged in all winter.

We just plug ours in periodically over the winter, at least once a month. But ours is handy to get at.

Glad I seen this, I was going to pull the bats out over the winter. But since it will be in my garage I won't have to do anything but keep it plugged in.

Thanks, I figured it was ok. As far as cost, I would say pennies a day. considering that most of the time the batteries are not drawing any juice and the charger is just idling.

I would just pull the batteries and put them in your basement, if it is a concrete floor put a 2x6 under them. Make sure you put a good charge on them before you put them down there. You will have no problems, my dad has been doing that with his batteries for years and no issues.

Do a search on this. This has been hashed out before.

I just have a thing about leaving mine plugged in all winter so I plug it in once a week or 2 for a few hours.

    • Watch your City Ordinances.  Some city's require a back-flow preventor, and it can be VERY expensive. I have both the battery backup, and the water driven sump pumps in my pit--all at different elevations, and feel very confident. When the water comes up, and the power goes out, the battery backup starts working.  After that the water driven sump pump will kick in.  The water driven pump will keep pumping until the power is restored and the main pump returns everything to normal. There is always water pressure in a power outage (from the tower).  Cities keep the tower full for fire protection
    • So proud of my 93 year old dad.  It's getting tougher and tougher just getting him out there, but he still knows what to do once there.    
    • I still gotta tag Moose! I'm going for a Tom only!!   (Personal thing) is ,,, I want to do it with my bow
    • Shaggy parasols are coming up in the shade garden again. Yum.  
    • VTX129 has a great point on nothing smaller than 9". I have a HB 998Ci HD unit. The bottom features that I can pick up are incredible- however I sometimes have a problem picking fish up on it. I have tried to keep my SI width narrower to help ID fish. Overall fantastic tool. The hard to soft transitions are easy to see as are rocks and so forth. On the HB units the larger screened ones come with the High Def transducer.  The smaller units come with a compact transducer. You can find some great prices on models that are being phased out - but they also will quit repairing those units sooner as well. Trade off's. Check out Universal Mania and some others online for pricing. Bass Boat central has a lot of info under Humminbird and Lawrance topics.   Good luck   Steve
    • CM I agree...and Chicago seems to find those diamonds in the rough...not sure how their AHL team is or if they have more of these "sleepers" coming up from somewhere but I bet they are right back in the finals within a 2-3 years with or without Q.   Another article that came in last night on Fletch/Wild http://nhl.nbcsports.com/2017/04/25/wild-exit-early-fletcher-stays-positive-a-familiar-refrain-in-minnesota/  You might have to Cut/Paste
    • Same have to give them a try once they come out.
    • Can't wait to test that Sprinker. 
    • lots coming thru for a couple days now.  had fun whistling with a couple yesturday. 
    • I wasn't able to catch it live and when I tried finding it after the fact it wouldn't play on my laptop for some reason. I do admire Bowman for being visibly ticked about their early exit, but I think that may get pushed a little too far. You tick off Q and he might just walk out the door. Bowman just fired one of his buddies and Q isn't too happy about it. We will see how that plays out. I think the Hawks are in a tougher position cap-wise than the Wild and have been for a few years. The difference is they had been getting no-name guys to emerge and contribute. They could be on a very slippery slope in Chi-town. We will see how that plays out.
