For example C10, C5, C20 batteries backup period are affected by the rate of charging and discharging current. A battery have a charging/ discharging current of 10 Ampere according to the manufacturer specification and it has a 10 hour backup. If we charge the battery at the rate of 15 Ampere, how will battery backup period decrease? How will this change at 20 Ampere?
Hello Mr.Kumar.
It's strongly depends on the type the batteries,for example if it,s li-ion or li-polimer rate of charging can at 150% of nominal can warm the batteries and reduces the life cycle,and if you charge by more than 300% nominal amperage it could be explode(and i had experienced that during one of my works)but if the batteries is like lead acids,it damages the batteries faster,but you know that the nominal charging current of lead-acids usually is high.
Back up depends upon the capacity of the fully charged battery,What ever the charging will hold hood till the battery is fully charged.charging at more than the rated charging current will reduce the life of the battery.Sealed batteries may explode when you charge at heavy charging current than normal current specified by the manufacturer.
