Specifications

Capacity
4800 mAh

Capacity

The amount of energy that a battery can store in milliampere-hours (mAh). The higher the capacity of a battery, the more it can hold with one charge. Larger batteries also require more time to charge.

2. Capacity makes sense when comparing batteries of the same size. For example, 18650 batteries usually have 2300-3600mAh, while AAA batteries have around 1000mAh.
Size
21700
Type
Li-ion

Type

The two main types are Ni-MH (Nickel-Metal Hydride) and Li-ion (Lithium Ion).

Li-ion
Li-ion batteries are the newest rechargeable battery technology, which offer more charging cycles compared to older ones based on Nickel or Lead, but with a higher initial cost.
Voltage
3.7 V
