14500 Batteries

14500 rechargeable batteries are AA-size lithium-ion cells built for compact, high-output flashlights and keychain lights. Most are 3.7V Li-ion (with some USB-C onboard-charging variants); they share AA dimensions but pack the punch a single-cell flashlight host actually needs.

This collection focuses on the cells flashlight enthusiasts actually buy: high-drain Vapcell INR cells for performance hosts, USB-C button-top picks for quick top-ups in the field, and 1.5V Li-ion options when an AA-spec device requires the lower voltage. Use them in compact EDC lights from Lumintop, Reylight, Convoy, Manker, and other 14500-compatible single-cell hosts.

Confirm voltage and tip type (button vs flat top) for your specific flashlight before ordering. Cells ship from the U.S. and arrive faster than overseas vendors, so you can rebuild a daily-carry kit or grab a spare for travel without waiting weeks.
