Batteries not disconnected for winter storage

Postby Kikaboo » Mon Nov 13, 2017 3:57 pm

Should I be pissed? I just checked my boat that is shrinked wrapped and winterized. Apparently the marina did not disconnect the batteries. It's to late to do it now since the boat is already wrapped. Is this going to degrade the life of my batteries? I'm in the Northeast and the boat will be wrapped and on the hard for another 5 months.

If fully charged before wrapping, you 'should' be OK.
I do not disconnect the batteries for storage, BUT, I leave the AC & converter switches on with the AC plugged in. Once a month, I plug it in to top off the batteries for a day.

Were your battery switches off? That will help. Otherwise they most likely will be drained dead and it will hurt your batteries. Hard to tell, but I would think some shortening to the life is expected. The good news is you might have some battery warranty left if you do need to replace.

The battery that has the radio preset memory wire attached to it will likely be dead by spring, it draws a little current even with the battery switch off. The bilge pump float switch is always powered as well but in theory it shouldn’t draw any power.

My brother didn’t unhook his batteries last winter and the one with the radio and bilge pump float switch connected was dead in the spring and had to be replaced.

The big one that is always powered are the CO detectors which do pull power and will kill the batteries even if switched off. Ideally if you could access to the shore power connectors (put a small flap in there and plug in once a month or so. Otherwise they will be completely dead (with CO detectors) and if the do die and it freezes the battery will freeze and crack the case. That is why you have to keep them charged during the winter.

Ideally you would even want the batteries out of the boat and just charge them at home once a month. You can simply use the jump studs to open and close the hatch, just make sure to cover the battery cable ends. A half of a year is a very long time to go without charges. They will self discharge between 1 and 15% each month just sitting there. Once they reach about 80% lead sulfation will start. The cold will help slow the discharge rate down. Ideally its not good to go below 32F as the charge state drops for the reasons above. ;)

Well I’m glad I posted my question and thanks for the responses.
I also just realized because the marina installed a zipper door I can infact get to the shore power outlet by the swim platform. I can not open the hatch due to the shrink wrap but I can plug into shore power every 3 to 4 weeks over the winter and charge up the batteries. Any idea generically how long I would need to leave the boat plugged in and charging if I did that once a month? I’m assuming a few hours might not be good enough.

Ideally a overnight, but a few hours would help top it off for sure. Go inside and make sure all the 12V breakers are off, and the 12V switches are turned off. Then disconnect the CO detectors. Then on the AC panel you can make sure that you have the breaker on and the battery charger on, so that you don't have to get in and out all the time. That way you can walk up and plug it in. If you have one of the "kill-a-watt" units you can simply plug it into the wall and then the boat into it (with adapters) and then see when the current levels go down. Then you will know that they charger is done.
Thanks, Chris

Fortunately where we are located doesnt require a haul out for winter so most boats stay wet at the dock/slip over winter and on shore power ( including a 1500 watt automatic engine room heater in our vessel, house battery charger, and the two heat pumps to keep the cabin above 50 F). If any one dry docks for the winter there isnt any AC power available so a full winterzation is required! Dont know of any of our dock mates that dry dock over winter. I do agree that the CO and Fire/smoke Alarms, and engine room halon system, stay connected and the radio memory as well. Even though we have a group 8D AGM house battery we have accidentally left the house battery charger off for 2 weeks and when returning to the boat the voltage was down to 12.6 VDC when we discovered the charger was turned off. For those of you that have refrigerators that automatically switch from AC to DC as ours does, that would be a significant load when you disconnect from AC if you havent turned off both the AC and DC breakers to the fridge!

I suppose getting to your stern breaker panel and your cabin breakers might be a little difficult with it all wrapped up. Hopefully you can wriggle your way in. One mechanic told me those main circuit breakers in the engine room can be tripped and they cut 100% of the power connections to the batteries (this is the one you had trip on you over the summer). I haven't verified this, but would be good to check out for the future, or see if anybody else knows about that.

On both of my boats they wired some of the breakers directly to the battery side of the battery switches, there wasn't anyway to disconnect them short of actually trying to blow the circuit breaker. :shock:

Regardless of what side of the main battery switches the cabin breaker feeds are connected to why not just turning off those breakers? If any loads are also connected to the batteries B+ "in" side of the breakers that would mean that the circuits that are also connected to the inlet side of the breakers, dont have over load protection? I may be missing something here.

Update... I am at my boat now and can gain access to everything aside from the engine room as there is a zipper door in the aft area of the shrink wrap. I have now run a long extension cord across the parking lot and plugged the boat in so I can energize the battery charger.

I temporarily turned on the battery switches as I wanted to get a reading. I discovered the marina disconnected the port/starboard starting batteries but left the house battery connected. Seems kind of strang they did that. Maybe they didn’t get my message that once the house battery was disconnected they would need to attach 12v to terminal under the seat in order to operate the ER hatch.

So with my staring batteries disconnected it appears I’m only charging the house battery. No issues with that right?

They will self discharge between 1-15% per month. Hopefully it will stay cold so they will be on the lower side of that number, and then you would be fine. I sure would put them on the charger overnight once you get it summerized and let them take a full charge once you can access them.
Thanks, Chris

And hopefully the loose ends of the battery cables are isolated from each other and the positive cables aren’t touching any metal.

I was wondering about that myself.

Just a thought, If you have a shore/land 120 VAC feed to the boat why not just leave it connected?
Also, when our 3X main battery switches in the engine room are in the "off" position our 1X group 8D AGM house and 2X Group 31 AGM engine starting batteries are still connected to the house/starting battery charger feed and will go to a float voltage of about 12.8 VDC when all 3 batteries are fully charged.

The battery cables are probably disconnected from the battery themselves.

I wonder why if you had a dry docked shore AC feed available to the vessel when pulled out why disconnect the battery terminals from the batteries? Possibly the marina's SOP? As we also have a 1.5 kW automatic engine room heater we would want that to be powered if we ever needed to be dry docked.

Gofast,

Traditionally the boats are fully winterized and no need for power, while on the hard. You wouldn't run heaters as there wouldn't be a need. Most yards don't have power available for the boats because of this. The disconnecting of the batteries would be normal practice because of loads that can't be disabled and would totally drain the battery over the storage time. The strange thing is that they don't either fully remove them or give a way to charge before being shrink wrapped up, as the tend to self discharge over time. It could be a long winter with boats up on the hard for 4-6 months.
Thanks, Chris

Up in the real cold the discharge rate it very low. I left my batteries in my boat the entire last winter, terminal disconnected and when I brought it out in the spring and put a battery charge on them they still had 80% charge left.
