[RE-wrenches] RETURN AMP SETTING

[Mark Frye]

Steve,
 
Just to make sure I am not missing something, there is no way to directly
set Outback equipment for a particular return amp rate. Rather one must
observe the charge cycle and set the absorption timer accordingly.
 
Do have that right?
 
Thanks,

Sorry all. I was out on a little three day vacation. 

 

I usually program return amps setting to usually 2-3% of the overall battery
bank capacity. 

 

Usually and depending on the battery type or manufacure when the current
passing from the charger to the battery drops to this Return amp setting
technically the batteries are charged.  

 

Because batteries are technically buckets of water with holes in them, they
will never stop pulling current, nor will they never be fully charged.
What happens is they start to draw a minimum of charge current from the
charger.   This "Maintenance current" usually is between 2,3,4,5 percent of
the overall battery bank capasity. 

 

With the Return amps setting you can get the batteries close to that charged
setting.
