How Long Does It Take To Recharge Batteries. Batteries usually take several hours to recharge. Suppose we took 13 Amp for charging purpose then Charging time for 120Ah battery 120 13 923 Hrs.
However in this scenario most batteries recover after a quick jump start as long as the vehicles charging system is working properly. I have developed a charging ckt that I can set the charging current to any value from 160ma to 1 amp. The amount of time it would take to charge would depend on the type of battery charger.
The safest charging current is capacity10 or 140 to 250 mah.
This charger can recharge both models AA and AAA at once. The good news is that you can leave it charging for a long time and not hurt the battery. Keep in mind that you can recharge 2 pieces of each model at the time. Can be charged up to 1000 cycles.
