1500mWh is equal to 1500mAh
mah refers to the capacity of the lithium battery in milliamp-hours. mwh stands for milliwatt hour and is used to describe the total energy of a lithium battery. The calculation formula is that the total energy of the battery is equal to the rated voltage of the battery multiplied by the capacity of the battery. Therefore, the nominal voltage of the 18650 battery with a capacity of 1500 mAh is 3.7 volts. It can be calculated that the total energy is equal to 1500 x 3.7 = 5550 mWh, so the energy of 1500 mAh 18650 lithium battery is much higher than that of 1 18650 lithium battery. 500mAh. that of 1500mWh.
First of all, we need to indicate some units on the poster:
Watts = Volts*A, or W=V*A
In en in other words, MWH = MAH * V
Therefore, the two are not the same unit and do not have an equivalent relationship.
If your battery voltage isof 2.775 V, then the energy of 2775 MWH is equivalent to a battery with a capacity of 1000 MAH (2775/2.775=1000). In other words, if you want to convert MWH to MAH, you need to know the battery voltage! MWH/V=MAH. Generally, the voltage of nickel-metal hydride batteries (mainly rechargeable AA batteries) is 1.2 V; the voltage of lithium-ion batteries is 3.7 V. Your battery voltage should be indicated on it, you can see it at a glance.
Finally, I would like to add that MWH is the unit of energy and MAH is the unit of capacity.
