Specifically however, 18650 lithium mines ontario-ion batteries are larger both in length and width than standard cells. The numbers, 18650, refer to length and overall circumference. Like most rechargeable cells, their power is rated in milliamp ere-hours (mAh). These mAh designations are often numbered such as 2200, 2400, 2600, 2900, and 3100, which all relate to amount of energy. The higher the number, the more power the battery possesses.
The best temperature to store a rechargeable battery is around 60 degrees Fahrenheit. As they sit around, they start to lose some of their charge. This is called self-discharge, and it refers to the battery losing capacity without being used. Different types of power cells have different self-discharge rates. The ones containing nickel discharge fastest. This means that any Nickel-Metal Hydrate or Nickel-Cadmium rechargeable battery will self-discharge slightly faster than other types.
