mAh Battery Life Calculator is an online tool used in electrical engineering to precisely calculate battery life. Generally, battery life is calculated based on the current rating in milli Ampere per Hour and it is abbreviated as mAh. Ampere is an electrical unit used to measure the current flow towards the load.
When it comes to online calculation, this battery life calculator can assist you to determine the time that how long the battery charge will last. For example, a circuit connected with 800 mAh current rating and it is connected to the load of 40 mAh. Then the battery will last for 20 hours.
It takes 21.6 hours ( 21 hours and 36 minutes ) to charge or recharge aa size 1800mAh batteries with charger that has 100mA current output. In total 6.2 hours ( 6 hours and 12 minutes ) is needed to charge or recharge 1800mAh batteries with charger that has 350mA current output power. Basics
2000mAh = 2Ah Consider Charge Level: The battery is already at 50%, so only 50% of its capacity needs to be charged: Effective Capacity = 2Ah × (1−0.50) = 1Ah Calculate Charging Time: Now, divide the effective capacity by the charger’s current: Charging Time = 1Ah / 1A = 1 hour
let's say you have a 100ah lead-acid battery. 100Ah lead-acid battery has a recommended charge and discharge rate of 5 amps let's say you have a 100ah lithium battery. 100Ah lithium-ion battery has a recommended charge and discharge rate of 50 amps How to convert c-rating to time?
For instance, a 100Ah battery can be safely charged at 50A (0.5C) to 100A (1C). Battery chemistry: The type of battery affects charging characteristics. Lead-acid batteries generally require a lower charging rate, often 10-25% of the capacity, while lithium-ion batteries can tolerate higher rates, typically around 0.5C to 1C.

mAh refers to the amount of charge a battery can hold over time. A higher mAh rating means the battery can provide energy for a longer period before needing a recharge. For example, a 2000 mAh battery can theoretically deliver 2000 milliamperes for one hour. If used in a smartphone that draws 1000 mA, it would last about two hours.
Specifically, 1 mAh is equivalent to supplying one milliampere of current for one hour. Thus, a 20000mAh battery can theoretically deliver 20000 milliamperes of current for one hour, 2000 milliamperes for ten hours, or any equivalent combination of current and time. Converting mAh to Amps. To convert mAh to amps, we simply divide the mAh value ...
For example, a 20,000 mAh charger can fully charge a smartphone with a 3,000 mAh battery around six times, depending on efficiency loss during the transfer.
