How many mAh is an 80 Wh battery?

Introduction How many milliamps does an 80 Wh battery have? There is no direct conversion between the two. Watt-hours Wh and milliamp-hours mAh are different units. The milliampere-hour is the unit of electricity. For example, a cell phone lithium battery contains 120

How many mAh is an 80 Wh battery?

Both cannot be converted directly.

Wh and mAh are different units. The milliampere-hour is the unit of electricity. For example, a cell phone lithium battery has 1,200 mAh, which means that a current of 100 milliamps per hour can be used for 12 hours. The watt hour is the unit of electrical power. For example, the physical meaning of 1 kilowatt hour is the electrical energy consumed by an electrical appliance with a power of 1 kW operating for 1 hour.

Battery Conversion

Usually, an 80Wh battery is basically a 3.7V rated voltage battery, since the capacity of the battery can be expressed in Ah or Wh. is 3.7V*xah=80wh=80vah, and the current can be calculated=80÷3.7=21.62ah=2162mah, so to be precise, the 3.7v80wh battery is 2162ma.

Of course, if it is a battery with other name voltagesinales, Wh is a quantity directly proportional to voltage, current and time. mAh is generally used as an indicator of battery charge and discharge. It is an indicator directly proportional to current and time. Well, to make the two values ​​comparable, you need to know the link between mAh and Wh: the voltage.

The battery capacity is divided by the charging current, then multiplied by a factor of 1.2, and the unit of time is hours.

Note: Typically, the battery capacity is listed on the battery in milliamps. The higher the value, the greater the capacity. For example: 1200 mAh means the battery capacity is 1200 mAh. At the same time, chargers are usually marked with the charging current, also in milliamps.

For example: battery capacity is 1200mA, charger charging current is 600mA, charging time is (1 200mA/600mA) × 1.2 = 2.4 hours, then this battery uses this charger charging time is 2.4 hours.

Note: The calculation method above does not apply to new batteries.

Battery charging time can be calculated using the formula: battery capacity/charging current*60. For example, the battery is 2500 mA and the charging current is 500 mA, then 2500/500*60 = 300 minutes. calculated. In fact, this is only a theoretical time and charging may take longer, because this charger does not charge at constant current. That is, as the charging time becomes longer, the charging current will decrease relatively.

Generally speaking, there will be no problem after 8 hours of charging. When charging, you can touch the surface of the battery with your hand. There will be a slight warmth, which means the battery is well charged. The highest charging voltage of a nickel battery-1.2V metal hydride is about 1.4V. You can use a multimeter to check if it is fully charged. This charger takes the same time to charge one battery as it does to charge multiple batteries because its outputs are independent of each other. Take a look at the 1.2V-500mA*4AA 500mA*2AAA output, which shows that this charger has four independent 500mA outputs.
