89SP charger/converter info needed. How many converter/chargers needed?

[GARY MINKER]

A pair of charger conveerters is like only having one arm. Better than no arms. The older or more modern units have only one function. They make a set voltage and they do it for ever. some can be set. Check your battery manufacturer and set the converter for the EXACT float voltage within .1 volts. Thats point one or you will slowly roast the batteries if you go overboard. .1 under is better life wise than .1 over. You only loose dry camp capacity if you are under and you bake the plates when you go over. It matters not if they are wet, agm, or gel. Leave the equalize charging to your engine alternator, or one of those cutsie little smart chargers that really have no brains anyway. The equalizing or refreshing charge as the big bank guys call it today is less of an issue in agm and gel. That was a sulphation issue with wet cells. I have a pair of 65A switching supply precision DC supplies set to I forget what but it is about .2V under ideal and my precious Sonnenschein monster cells will live a lifetime. gary 85pt40 --- On Sat, 7/24/10, Bluebird Bob wrote: From: Bluebird Bob Subject: [WanderlodgeForum] Re: 89SP charger/converter info needed.

Do most coaches have 2 chargers/converters? I have a sw in the shore power door that is labled HIand LO.I understand that it selects one(LO)or both(hi).Does everybody have this sw? And where do you leave the sw positioned? How many AMPS do I need for a charger/conveter? > Thanks for any help > Ed Gardels 89SP > Arlington, Texas >
