CAN 2 9-VOLT BATTERIES IN PARALLEL BE RECHARGED FROM A 12 VOLT SOLAR PANEL?
Nov 30th
Question by Dinger:
Can 2 9-volt batteries in parallel be recharged from a 12 volt solar panel?
can 2 9-volt in parallel be recharged from a 12 volt solar panel, or would they only charge up to 6-volts each?
I know they can not be charge in series, the 12-volt is to much for the 9-volt, so they have to be in parallel. but will a 9-volt recharch to 9-volts if the input is only 6-volts.
I know a capacitor can save more then it receives, but can a battery?
