I had the burned up battery circus. Bad battery charger. If you have one with a big transformer, try for one without it. see CW catalog., or American RV Mart, it is called an electronic upgrade. usually located below the fuses or CBreakers.

Ernie, we just spent two weeks at Lazy Days and had no problem coming to Florida or while we were there in service.
However, we left last Saturday every once in a while all lights in panel lite up
like Christmas, gas gauge down but no power loss>>>>?

Ernie forgot to tell you. Better be careful after removeing the battery to charge it, cause when hooking it back up on a RV that has a draw on the battery it will arch a spark when hooking the cables back up. That could make the batt blowup
on you.

make sure to check the water levels in your batteries and if low, fill with distilled. when charging batteries, always remove caps to release the hydrogen & reduce possible explosions. other advice is helpful!

Laura, if your battery is burning up you should have your inverter checked to see if it s overcharging the battery. Overcharging can cause the water to boil right out of the battery. The inverter is supposed to sense when your battery is charged.

What Ernie didn t tell us, is whether or not the unit was plugged into 120v or not. This would have told us if the converter was bad or not. With the unit plugged in, the batter charges, he could had worked on the elec. system and charged the batter

If you are damaging batteries from overcharging, check the specifications of your converter. Not all converters have automatic chargers that reduce charge rate. Some converters have constant charge rate that will overheat the battery causing it to be damaged. The owners manual of the converter will warn you not to leave RV plugged-in all the time. I would suggest this converter be changed to one with an automatic charger.

If your RV is equipped with an inverter make sure the inverter is programmed for the size of battery bank you are trying to charge. This is done at the remote panel. If your RV is not equipped with a remote panel then one will need to be connected temporarily to complete programming. The inverter needs to know amp hour capacity of battery bank, wet cell or gel cell batteries and cool or warm climate.

Removing battery caps when charging was the proper thing to do years ago. On present day batteries we want to leave the caps in place and charge at a slower rate. The caps are spark resistant caps to prevent a problem from a gassing battery. Do not remove caps when charging.

HI Ernie,
I recently bought aused RV on ebay. Was amazed the had a number of problems that needed fixing. I spent day and a half before he got them all repaired. I drove it around 700 miles bringing it home. Three days later the battery was dead. Your lesson taught me how to use a search light and to check things for power draws before calling a mechanic. I know it cannot be the generator, or I would never have made it home on the batteries.
Thanks for the tips and I will be looking forward to more.

I am having the same problem with my RV battery. I come home from a trip and a week later the battery is dead. I started disconnecting the cables from the battery to stop the draw. There were no lights left on, believe me, I checked and rechecked. Can something like the clock on the microwave kill the battery in a week s time? If not that then I can t find the source of the draw. How do you chck what type battery mates up with your power converter? I thought any deep cycle marine/RV battery was okay. What am I missing here?
