Battery not holding a charge

Seems that after taking full charge it takes only a night for the battery to be down to 1/3. Battery is one year old and came with the Greyhawk. Battery is full of water and all the connections area tight and clean. Is this just bad battery?

Does there appear to be material adhered to the plates in the battery?

Hey Hawk, hello and welcome to the group.

Jim, pick up a hydrometer and measure the battery. They're cheap... it will give you an accurate reading on whether or not the battery is good or needs replacing.

Nothing on the plates and off the the auto parts store to buy a cheap hydrometer.

Hard to tell without knowing how much you are pulling - that could be correct if you pull too much or something is draining it. If you are in the market for a multimeter, get a good AC/DC clamp meter -- they are great for this sort of thing. The DC ones are harder to find, so look close. Got mine at Sears...it was a pretty good model for about $50.

Most auto parts stores have a battery tester that can tell you in 3 minutes if the battery is bad.

Take it with you.

If you bought it new remember you have a 2 year warranty on everything.

Actually, most batteries are warranted for much longer than that...

I know this is a Class C forum, but this applies across models. My trailer (see below) had 6 guage wire run from the battery, all the way to the back for the power distribution panel - probably 20-30' of pretty narrow guage wire.

A few things about batteries - for a float charge you need to be getting 13.4 V @ the terminals....that should give you about a 1AH charge rate (VERY SLOW). So, lets say my factory 2 stage converter is doing a good job and putting out 13.6V for trickle charge. The issue now is cable loss.

I used http://www.nooutage.com/vdrop.htm to calcualte how much voltage drop I get across that long cable run. Assuming 25' of 6awg and only 1 amps of draw, I don't do well with .2% voltage drop. That sounds like a small number, but it means I'm only putting 11V on my batteries. IE: My batteries had NEVER had a good charge off the converter.

Even if my converter was putting out a much better 14V, at .1% drop over that cable I'm only getting 12.6V at the terminals - IE: getting what a fully charged battery has - and as I'm not putting more voltage on it than the battery has itself, I am getting no charge!

No matter how much I ran the generator, I could not make it through more than a night with no heater!!

My fix was replacing the 2 stage with a good 3 stage converter, and relocating the converted to the front of the trailer. I ran larger gauge wire back to the power distribution panel and a nice 4G wire the ~5 feet from the new install location to the batteries. I also replaced the now shot 2xGroup 24's with 2xGolf Carts. I'll try to get around to doing a proper write up on this mod as I suspect MANY more people out there need to consider doing something similar.

It wasn't a simple job - and a fair understanding of cabling/wiring is recommended. However, now I can boondock with confidence.

To really see how your batteries are doing, get an inexpensive 12V meter and a hydrometer. Should be out less than $30 for both and be able to KNOW where you sit.

This is a long read - but very good info and where I started. 12V Side of Life Then when I got serious about the mod, I got involved over at the Wind Sun Forums. Those wind-sun guys are solar, but the concepts are the same and that is where I learned the most.

-Good luck!
