Powerful, durable, and rechargeable, the ARB-L14-1050 battery will power your light for a longer duration than a standard AA battery. Usable in most AA-powered flashlights and products. Note: The price is for one battery and is packed one battery per package. This battery does not feature a USB charging port. It needs a separate charger to be recharged. 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.
