|how one can know the charging time, discharging time of a
12 VDC battery ?
If i have a battery of 12 VDC , 4.0 AH , how long will it
take to charge from a charger (power supply) of input 220
V , Output 15 V and output current of 3000 mA and how long
will it take to discharge whether using or not ? How much
backup will it give ?
