80 Wh is equivalent to a 48 Wh cell phone battery.
Both cannot be converted directly. 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 has 1,200 mAh, which means that a current of 100 milliamps per hour can be used for 12 hours.
The milliampere is the unit of measurement of electric current, represented by the letter mA. A milliampere is equal to one thousandth of an ampere. Among them, the ampere is the unified international unit of electric current, represented by the letter A. The physical representation of electric current is represented by an English capital I.
Battery conversion:
Usually, an 80Wh battery is basically a battery nominal voltage of 3.7 V. , since the capacity of the batterycan be expressed as ah or wh, the relationship is 3.7v*xah=80wh=80vah, and the current can be calculated=80÷3.7=21.62ah=2162mah, so to be precise, the battery 3.7v80wh is 2162ma.
Of course, if it is a battery with other voltage ratings, 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.
3.7V 1200mAh lithium battery charging problem!
LZ don't worry
You can replace it with 5V600MA, but it may make the charging time longer. This should last 3 to 4 hours.
However, LZ should not use a 5V2000MA (PSP2000) charger, as this will exceed battery regulations and affect battery life.e the battery!
I still hope LZ will use the original charger
Please use with caution!
Lithium ion batteries are the most taboo in overcurrent, overvoltage and high temperature charging. Improper operation can cause an explosion or at least damage from bulges.
Before operating, it is better to confirm the output voltage and current of your power adapter. If the voltage is too high, for example above 4.3 V, charging may damage the battery. to overvoltage. And damaged. Does 500mA refer to output current? If so, the charging current is acceptable. If the AC adapter reaches full power, it will become hot and may break after a long time. If the output current is not 500 mA but more than 1.2 A, it may be dangerous to charge the battery directly.
For a5V500mA output power adapter, if the voltage across the battery can be monitored in real time or the charging time is limited to about 2 hours, emergency charging should be possible via direct connection. connection. . However, under full load, this small power adapter may overheat and become damaged or temporarily protected.
For reference!
