Shore power charge house batteries? February 06, 2016, 03:13:15 pm Yahoo Message Number: 158553Do the house batteries stay fully charged when the coach is stored and hooked up to shore power?

And as you know, it doesn't charge the battery in the engine compartment except for those LDers clever enough to wire it.Ed & Margee Fort Worth

Reply #4 – February 07, 2016, 04:26:18 pm Yahoo Message Number: 158591"Do the house batteries stay fully charged when the coach is stored and hooked up to shore power?" If you are referring to all but the most recent LD vintages, the answer is that not only can the converter not fully charge the batteries, but can simultaneously boil away the electrolyte if stored connected to shorepower. This turned out to be an expensive issue for those with factory AGM batteries that were ruined prematurely. The most recent vintages have a multi-stage charger that will charge the batteries quickly and completely without overcharging. Likewise after-market converters can be installed in all the older vintages which will also work well.Steve

Re: Shore power charge house batteries? Reply #6 – February 08, 2016, 07:49:00 pm Yahoo Message Number: 158608We have a '09 MB and on page 40 of the Motorhome Manual, there is a section called 120V/12V Power Panel (Converter - Parallax 7345). "... the converter can supply up to 45 amps to charge the house batteries (not the chassis battery)." So I would make a wild guess and say your newer model probably has the same feature. Hope this helps.Ed & Margee Fort Worth
