Charging batteries with the engine
Hi all. I have a 2011 triple e senator 25d. Great motor home. E450 v10. Just curious, what is the output of the alternator vs the standard converter? It seems to charge the house batteries...

"To properly recharge them, you need a 3 stage charger."
No, you need a single voltage charger that is set at the specified Absorption Voltage (Vabs) for that battery. Leave it on until amps taper to zero and you are now properly charged.
You can then put the battery on a maintenance charge at its specified voltage for that.
Your single voltage charger at the proper Vabs will take the battery through its Absorption Stage and perhaps a Bulk Stage before that. (But not necessarily--whether there is a Bulk Stage depends on the charging rate--charging amps vs bank AH capacity-- and the starting SOC.) You could be where the battery goes straight to its Absorption Stage.
If you wish to argue about that, we should take it to the Tech Issues forum.
