I have a Magnum 2800 inverter/charger...I notice on the remote that it usually is in float charge....about 13.4 Volts....rarely I notice a 'full charge' at about 12.9V....is this because when I run anything on 12V the float charger will kick in to maintain the house batteries?..My fridge is 120V only and I have the ORIGINAL batteries from 2006...I know they are tired!!

Larry; There are 3 levels of charging and they should be set up according to the type of battery you have. If you have lead acid (wet cell), then the first stage is called "Bulk Charge" where the charge current is maximum until the battery voltage reaches 14.6 volts. Then it goes into "Absorption Charge" where the charge current tapers off in order to maintain the bulk voltage (14.6 volts) setting, again this determined by the battery type and size. At the end of absorption time (determined by battery bank size), the charger reduces the charge voltage setting 13.4 volts. After 4 hours of steady voltage of 13.4 volts the charger goes into "Battery Full or Full Charge state reading". You will seldom see this as things are being turn on and off without you even knowing it, example water pump running, water heater coming on(again even in ac mode the controls are still DC, lights being turned on, electric steps going in or out, even when you have your refer set to AC it still consumes 12 volt DC current for the controls.
I hope this helps a little and if you have any questions PM me. Keith
4 whopping cylinders on Toyota RV's. Talk about great getting good MPG. Also I have a very light foot on the pedal. I followed some MPG advice on Livingpress.com and I now get 22 MPG! Not bad for a home on wheels.
