THIS BATTERY IS NOT AN 18650, AND IT IS NOT COMPATIBLE WITH 18650 FLASHLIGHTS OR OLDER-STYLE CHARGERS (such as the ARE-C1 and other “C Series” chargers). COMPATIBLE CHARGERS ARE THE ARE-A2, ARE-A4, ARE-D1, OR ARE-D2. This is not the version of the battery with direct USB charging.

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.
