Usable in most AA-powered flashlights and is directly rechargeable via its Micro-USB port. (This battery can ONLY be charged with its built-in micro USB port. It will not charge in any charger.)

Notice: The price is for one battery and it packed one battery per package. It's not recommended to use more than two of these batteries in sequence.

Shipping Note: Lithium ion batteries are considered "dangerous goods" per US transportation regulations and can often only be transported via ground shipment. Orders containing loose batteries will typically take much longer than predicted to be delivered. Delivery times of 14+ days are not uncommon.
