How long does it take to charge a 800mAh battery?

How long does it take to charge a 800mAh battery?

Some batteries need a 4 hour charging then the max charger current should be 800 mAH / 4 hours = 200 mA. This is reasonable for simple and cheap phone batteries, and though battery may become warm, it will not heat up or burn.

What does output 5.0 V mean?

It means that it will provide a regulated (5.0 Volts) voltage DC (the = like symbol) till a maximum of 1.2Amps output current.

How long does it take to charge a 5v battery?

Since this is a huge battery with 22400 milliamp-hours (22.4 amp hours) you will need to charge it for at least 22.4 hours at a current rate of one amp (or 11.2 hours at 2 amps). Obviously nothing is ideal so you will need to charge it for slightly longer.

What does 800mAh mean?

Learn more physics! The mAh stands for milli-Ampere-hours and indicates how much electric charge the battery can provide. For example, if you discharge your battery through a circuit that requires 1 milli-Ampere of current it will last 800 hours before the battery runs down.

What is a 5V charger?

Example: The output of the charger is – 5V / 2.0A. If a smartphone is connected to a power bank, then that is Output charging taking place. This means that the smartphone is charging at 5 Volts and 2.0 Amps.

What does 5V 2.4 A mean?

Fast Charging
Understanding Fast Charging Amperage (or current) is the amount of electricity flowing from the battery to the connected device, while voltage is the strength of the electric current. Multiplying volts by amps gives you wattage, the measure of total power. Most phones and other devices are capable of handling 5V/2.4A.

What size of battery charger do I need?

As a rule of thumb your battery charger should be a minimum of 10\% of the Ah rating of the battery. E.g A 100Ah battery would require a 10 Amp charger as a minimum. To prevent overcharging you should keep the charger size to within 20\% of the total capacity.
