I don't understand why a battery I have in parallel with another battery does not charge.
The bigger of the batteries is connected to the charger. The smaller battery a 7Ah battery it is used as back up when the big battery is not connected.
The small battery goes flat I then connect it to the big battery, the voltage goes up slightly but not to the same voltage as the big battery, I would really like to understand why
