The 18650 rechargeable batteries are Li-ion batteries. They typically measure 18 mm thick by 65 mm long and possess a capacity between 2200 and 3400 mAh (milliampere-hour). These 18650 batteries are available in protected and unprotected forms.

Improper handling of 18650 batteries can result in damage to the batteries and electronic devices, as well as harm to the user. Buyers should also note whether the battery has a flat-top design or a nub on the end of the unit, as this affects the battery's compatibility with products. Buyers should consider the top items on the market to find suitable 18650 rechargeable batteries for their needs.
