Although similar in length to two CR123A batteries (end-to-end), these 17670 batteries have a slightly larger diameter than the CR123A batteries. They may not fit in all two-cell CR123A flashlights. Please check manufacturer specifications before inserting one of these batteries in a light to ensure compatibility. Putting a lithium ion light in a light that is not made to handle them can possibly ruin the light.
Please note that we cannot ship lithium batteries of any kind to an international address via USPS. International orders containing only lithium batteries will be canceled and refunded. International orders containing lithium batteries and other items will be held while we contact you for further information. Contact us if you would like a quote for DHL or another form of shipping, but be aware that the cost is much higher than via USPS.
