will this charger drain down the batteries if not plugged in for days or weeks? I have a guest charger that if not plugged in it will drain the batter

I have the 3 bank and it didn't cause any noticeable drain after 2 months of sitting.

I have not had this happen to me and have had one in my boat for over three years. It works great! I go fishing every two weeks and charge my batteries as soon as I get home. They are always ready to go on my next trip.

No the charger won't drain the battery -- Nor will it maintain it... Batteries will naturally slowly lose their charge while sitting unused -- Plus sometimes dependent on where the batteries are being used (boat, Car etc.) there might be a slight discharge to circuit leakage . clocks, lights, and the like. Just plug your charger back in a day or two before you use the vehicle .

pretty sure the batteries will maintain the charge. This is my first experience with onboard chargers but my buddies normally leave theirs plugged in and hooked up most of the time, as this onboard chargers are more like trickle chargers and can be left plugged in and hooked up. Hope this helpsTerry A

I have had mine in use for several months with no issues. It is off all the time when not in use so I am not sure what would drain the battery. A friend of mine has one going on three years old and has never mentioned issues with any part of it. One of the reasons I bought this one.

It might make the batteries not recharge quite as many times, but I do it all of the time and have had my batteries (Enloop) and the charger for more than a year. I do recommend that the charger be put in "soft charge" mode if you are going to leave the batteries in for more than 4-12 hours.

I've had mine for over a year. I just keep it on the charging base, use it, and put it back. I have never drained the battery, and I've noticed no drop in battery life with it being on the charging base 24/7.

Not certain about that. I have had my charger for over a year and have not had any problems. I purchased 6 new batteries last summer. The technician who installed the batteries said nothing about my charger affecting the batteries. Who was the source who told you that? It might be wise to check with the cart mfg. Also, before I ordered the charger I asked the company if it was okay- they said that there was no problem and if I did not like the charger to send it back. To me it's just a lower charge which takes longer for the batteries to charge. Good Luck.

I would ASSUME the batteries are not drained while plugged in to the power supply (which does not answer your question - I realize that). However, you should ALWAYS take the batteries out of a unit when the unit is plugged for any period of time (or not in use for any period of time) because batteries will leak and ruin the device. I have had several sets of different brands of batteries leak in the last few years.

When you charge you'r battery, do NOT leave it in the trimmer when not in use. The Trimmer will drain the battery even when not being used. I leave the battery in the charger after I charge it, unplug the charger, but I store the battery in the charger until I need it.John.

I have found that it will retain a charge longer than one day but it does slowly discharge. I would suggest that this be used as a last resort to provide limited supplemental power to a device. It is not very powerful.

I would say yes. This charger allows you to leave the batteries on the charger so they have a full charge when you put them in.

I have never noticed an issue with it draining the batterys. I usually plug it in after each use.

Yes, to a point. While no damage is done to the charger or batteries outright there will be over a period of time be a shortened life of the batter itself. As with any rechargeable power source it is best to deplete it as low as you can before recharging. Leaving it constantly plugged in means continuous heat which shortens the life span of the battery.

I think any battery will discharge after a certain amount of time, that's why a trickle charger is used on larger batteries.

This is a charger/maintainer. Your batteries should easily hold their charge for a couple of weeks without power to the battery. Once power is restored to the MinnKota, it should bring batteries right back up to spec. Have had several chargers and this is by far the best and most effective. It even senses battery temperature and adjusts charge accordingly.

No, this is not a "smart" charger. When you plug it in it charges for 10 hours and then shuts off. Period. If you put in fully charged batteries it will still charge them for 10 hours.

Lordy no. I plug in the charger with battery in , out , half in. Pull them out early. Short charge etc. overload and over discharge, it handles it fine. My battery life is shorter than some but it's a tool.

Considering this charger has a test/refresh feature, leaving the batteries on the charger will not damage them even though they are being trickle charged. Though i usually will not leave batteries on a charger for much longer than when it says it's full due to the possibility that they could weaken the batteries causing you to leave the batteries in refresh mode which takes up to 20 cycles depending on how bad the memory effect is on the batteries.If you buy the staycharged batteries that don't lose charge within a year there is absolutely no need to leave them in the charger, but if you got older batteries leaving them on will keep them charged whenever you need them.
