This is a battery tender for 24 Volts system. If it is left plugged in it will provide 2.5 amps per hour to the battery. Normal systems have about 1500 amps in the two batteries. This is math problem, uses 50 amps in 12 hours to run things, 30 amps are replaced for a net lost of 20 amps, go to sleep for 8 hrs. and 20 amps are replaced. Get a good digital volt meter 12.8 volts is 100% charged, 12.6 volts is 75% charged, 12.5 is 50% charged System voltage should not go below 25 volts as will decrease battery life and stress your charging system. It is best to have a electrical source to run the day to day stuff and the Batter tender will keep the RV battery fully charged This is a battery tender for 24 Volts system.

If you are referring to the main engine starting battery then yes. If will not maintain the other system batteries, they simply are not large enough to do that. You will need to keep a check on the water levels unless it is a sealed battery.

I use my 12 volt on my bike all winter long. So if you have a 24 volt it should do the same thing.

I see no reason why it shouldn't unless you put a big load on your battery and the charger can't keep up

hi do you have to keep it plugged in all winter or even all week. can you just charge it up the evening before, mow, and then leave for the next week. doesn't it hold the charge? would appreciate your thoughts. thanks peggy ness

once a month is fine it is a deep cycle battery it wont hurt it if i gets a little low on charge. Most boat batteries dont get charged all winter and are still charged enough to start the boat.

Yes, that is exactly what I have done for 1-1/2 years. I take short trips that don't recharge the battery fully. This tops it off once a week. If you are in frigid weather and you mean, will it start a car at -30, your battery may not be strong enough to do that, even if it is fully charged. That is a different issue.

Charge it before storage & charge it a couple days before use , this kind of battery doesn't require to be charged all winter long.

Don't know for sure as I bring mine in. Shouldn't hurt it other than the charging time will be less due to shorter daylight and charging itself may be affected by the cold. You will see less on time.

I purchased one back in the summer for the grand-daughter, so this is our first winter, but it is sitting out in our detached garage in cold Tennessee weather. It's hasn't been extreme cold yet, but you have given me an idea that I might put a folded up blanket over the back end where the battery is, just in case. Taking the battery out and bringing it into the house is not something I personally want to do. It might be an easy thing, but this 71 yr. old granny doesn't want that job.

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

Although there is some confusion in the information on LiFePo batteries, the instructions with this battery says you can use this kind of charger to charge battery. There is no information on using the charger for winter storage. Although the battery is supposed to retain a charge for a year w/o use, I have kept it plugged in to my battery tender w/o any apparent consequences. Some reviews say that this type of battery does not like "ghost voltage" which may drain the battery (my bike's computer does not seem to have enough draw to impact charge). Overall, the major problem with this battery is that it does not tolerate cold temperatures as well as a normal battery. It has been suggested to me by a service manager that I should warm the battery by turning the ignition and lights on prior to early morning start. It does seem sluggish when starting the first thing in the morning. This seems to help. Battery Tender makes a charger for the LiFePo but will not be available until early summer. Hope this helps.

it doesn't matter; just leave it in the sun to charge it! IF your unit won't charge from the sun, then there are 2 possibilities:1. your circuit board is faulty and you need to replace the whole unit.2. you live in a place with latitude above 41 degrees or so, so solar power DOES NOT WORK in the winter because the sun is too weak.Seriously though, it uses a pair of AA Nickel-metal hydride (NiMH) batteries but THE UNIT IS SEALED so you can't really get to them.

The cold does not affect this battery too much. My wife doesn't ride her scooter during the winter so the battery goes pretty low while just setting there all winter. However, I put a charger on the battery for a few hours and the scooter starts right up. I'm sure a trickle charger would keep it going during the winter but it's not going to be ridden so why keep it charged?

Yes. I disconnect the battery from my camper 'load' during the day, allowing the battery to charge, then switch back to battery in the evening. Just requires in-line switch for 'load' side of controller to camper and in-line switch from battery to camper. Has been working quite well.

I am sure it will, but I must say that I am having a problem getting mine to work right at this time. Not sure what is going on. Had a hard time getting it to work last cold season, did eventually work through the summer but now that cold season is here it want work as it should. Not saying that the maintainer is bad, could be batteries, but they are just 1 & half years old. I really don't know what to tell u at this time. If u do get one or even something else. would like to hear from u & how it working for you. Sorry don't have better info at this time.

I also leave it plugged in when not in use, keeps the battery from depleting during the loong winter

Hey there, I left mine plugged in this winter and it completely drained it and it wouldn't hold a charge. The note on the charger clearly says not to keep it plugged in at cold temperatures. So totally my fault. I went to Batteries Express and had it replaced(well there are actually two inside of it), just shy of 120 bucks, but cheaper than buying a whole new unit.
