Recharge Coach Batteries???

The batteries I currently have in the coach are Duralast Marine Batteries, 800 Cold Cranking Amps...I've check the fluid levels and the connections...all are well...if replacement is the answer...what is a battery you've had excellent service with?

Ok then, starting the Generator shouldn't have anything to do with the house batteries....as well as "cranking" the engine shouldn't have anything to do with them also. Therefore, I think the generator not starting is a separate issue from your house battery issue.

As far as your house batteries are concerned, I think that they are kaput and won't hold a charge. Running the engine for 30 minutes should have charged them up to a sufficient level that they will hold for quite a while. I think that by the time you "cranked" the engine a few times, it would be enough time for the house batteries to lose their charge.

Check their voltage after charging and monitor them for about 10 minutes. If the voltage drops off to less than 12.2 volts, you have a bad one and need to replace it. If you have multiple house batteries, it would be best if you replaced all at the same time.

Hope this helps

Sounds as if your house batteries are nearly dead.The short drive revived them a little. Battery level indicators are not accurate.Open up the house battery compartment and check level of electrolyte in each cell. If you can see battery plates, you need to add distilled water to cover the plates. If you have a 12 volt car battery charger of at least 4 amp capacity, hook it up to house battery and let it charge for 24 hours. Check battery voltage after charging, with digital volt meter, it should read around 13.3 volts. If battery recharges properly, it may start the generator.If battery(s) are damaged from being left in a discharged state, or lack of maintenance, they may need replacement. When connected to shore power, your converter should charge the house battery(s) but many of older stock converters can overcharge the battery and boil out the electrolyte. You must keep track of electrolyte levels and add distilled water as needed.

The batteries I'm referring to are "house" batteries.

Try this first. wire brush all battery cables and terminals till they are shiny.

Need more info. When you say "coach" batteries... what batteries are you referring to? House or Chassis?

Engine and Generator should both start off of chassis batteries. So if one starts and the other doesn't...sounds like and bad connection someplace..probably ground.
