Hi everybody
my question is about ups nowdays as there is shortage of electricity so if there is two battries sources battery 1 and battery 2
now let suppose battery 1 is connected with ups and the battery 2 is in parrallel connection with the previous battery 1 both are charging by ups
now if i connect another charger 12 volt to both of the battries then what would happen either it will damaged the ups or it will damage both of the battries i think the charging time will be reduced
i need answer
