Total Newbie Question: Battery Charging?

Hi. It seems there is a lot to know about batteries and electrical systems. I had no idea. I'm told that if I don't want my battery to fail, I need a device to keep it charged at home. What do I need?

There's several brands of battery maintainers, Battery Tender, Battery Maintainer, Battery Keeper. All work quite well in my experience. They're not very expensive.
You also need to check the liquid level in your battery once in a while. I check my once a year and top each cell off as necessary with distilled water.

I've been using the one I've had for years to charge car batteries. One day, I'll install the other type in the trailer.

I also have a solar setup, rarely use it though.

This book will tell you everything you need to know and more.

Hi, Jennifer;
I, too, am a battery novice. Bought a battery tender jr, which has worked well for me. I take the battery out of trailer before winter storage, put it in the garage and hook it up to the battery tender junior. That's as easy as it gets. Ordered it from Amazon.

Battery Maintenance

Depending on your situation, you may not need to remove battery from Scamp.
A clean and fully charged Lead/Acid battery can be left outside all winter.
To make sure there are no parasitic loads to drain the charge, disconnect the negative (ground) wire from its post.
Wash off any dirt around the terminals, dry well.
Check fluid levels in each cell. it should cover the plates but not be too full.

:in the old days and our old 6&12V batteries we were always told to make sure we stick them on a board and hook up the 2AMP trickle charger, if put on concrete floor the battery would die sooner than expected. I have no idea if today's batteries still have this problem.
Also when driving from different sites we have hooked up the MH to the Toad to keep the Toad's battery charged so when we hop in and go for a drive it starts right up, instead of just a Klick.

I keep mine out all the time, I plug into a garage outlet 15amp, with a RV ext. cord, about a day or two every month throughout winter and summer. Seems to work. Carl

Paul put the trickle charger inside the trailer by the breaker box to keep the batteries, permanently on the tongue, constantly charged. He sits in Peanut often to read by himself, so uses the 12V lights in there and the microwave (110). Might as well keep the batteries going.


In case you're having trouble with the "inverter/converter" thing:


Converter: battery Charger, that is, 110/120 to 12V
(A trickle-charger is a type of converter, plug it into a normal
110/120 outlet and it will make 12V power in your battery)


InVerter: 12V to 110/120
(this will run, say, an LED TV with a "regular" 110 plug by 12V battery power)




These are my mnemonic devices; hope I've got them right! (Pretty sure.)




PS: Peanut = our 73 amerigo: One shell with two nuts in it.

A belated thank you. This is very helpful.

Jennifer in Denver, if your Scamp winters in front of your house, plug the 120VAC power in, maybe every two months for an overnight re-charge and it should be fine. The converter will take care of it. Make sure there is no parasitic load (smoke alarm, or such, or a light left on). You can measure the battery no load voltage with a cheap voltmeter every once in a while to see how it is holding up.
Is the winter over in Denver? Or not yet.

In the Old days when battery cases were made of rubber and had soft, maybe tar covers on the top, they would discharge sitting on a concrete floor.
But since they switched to plastic cases, some time in the late 1950's to the early 1960's, that's no longer been the case.

Us olden day fellows must somehow keep up with the times

If your trailer has a converter (device that takes 120V shore power and converts it to 12V, to run 12V items and charge the battery), all you'd need to do is plug it in at home and leave it plugged in. The converter will do a passable job of maintaining the battery. Or you could do what I did, buy a small solar panel and controller and leave that hooked to the battery. Well, actually my trailer had a 7-pin plug for the tow vehicle which includes a charge line, so I wired the solar controller to a receptacle for that plug.

When I changed my distribution panel it came with a smart charge wizard. I leave my trailer plugged in at home and it takes care of its self. Check the water just before the camping season starts. in the 4 years or so I have added about a teaspoon of water. Works great for me. If I didn't have that option I would go with a permanently mounted solar panel.
