Battery charging time is the amount of time it takes to fully charge a battery from its current charge level to 100%. This depends on several factors such as the battery’s capacity, the charger’s voltage output, and the battery charge level. The basic formula used in our calculator is: Charging Time = Battery Capacity (Ah) / Charger Current (A)
A typical rechargeable battery gets fully charged in about six hours, and that’s the maximum time it takes even if the battery is dead. If you are using NiMH batteries, storing them at full charge and room temperature will keep them functional for three to five years.
The time it takes for the rechargeable batteries to be fully charged depends on the type of charger. However, if you use a regular charger for your AA batteries, you can expect one battery to be fully charged in six hours. So, simultaneously charging two batteries takes 7–13 hours. Meanwhile, AAA batteries take up to 6–9 hours to be 100% full.
Rechargeable batteries start discharging when they are not being used. It is referred to as self-discharge. This means you must recharge it before using it because it happens quickly, too. A typical rechargeable battery gets fully charged in about six hours, and that’s the maximum time it takes even if the battery is dead.
Based on your battery being a lithium battery and the charge rate being relatively slow, you assume a charge efficiency of 95%. With that, you can plug your values into Formula 2. In this example, your estimated charge time is 8.42 hours. Using Formula 1, we estimated this same setup to have a charge time of 8 hours.
It usually takes about three to four hours to charge any AA battery. This is more efficient than regular chargers, which take about 8-10 hours to charge two NiMH batteries fully, three hours to charge Li-ion batteries and about eight hours to NiCad batteries.
