Charge rate for Progressive Dynamics PD 4645?
Does anyone know what the charge rate, in amps, this unit does at max?
Forum Discussion
With 45AMPS capacity mean when you hit two deep cycle 12VDC batteries with 14.4VDC BOOST Charge from the PD4645 unit it should re-charge those two batteries from a 50% charge state to a 90% charge state in around three hours time using smart mode charging technology. To fully charge those same two batteries to a full 100% charge state it will re-charge them in 12 hours time.
You can immediately start using a 90% charged state battery and expect almost full performance for around 12-14 deep cycles from 50% charge state to 90% charge state. After that however you will need to do a FULL 100% charge state to keep from doing harm to your batteries.
The rule of thumb is a deep cycle 12VDC battery will demand right at 20AMPS of DC charge current per battery and then slowly start dropping back on current demands as the charge continues.
So says Progressive Dynamics at any rate...
We follow this re-charge schedule all the time when camping off the power grid and have had great success maintaining our 255Ah battery bank since installed in 2009.
