Product Information
The OrcaTorch 21700 USB-C Rechargeable Battery is a 3.6V, 5000mAh (18Wh) lithium-ion cell with the USB-C charging port built directly into the battery, so it can be charged from a standard USB-C cable without a separate charger. It powers OrcaTorch dive lights including the Orca7, D700, D710, DC710, ZD710 MK2, D710V MK2 and D720, and is rated for about 500 charge cycles.
Who it is for
This is the battery for divers who already own a compatible OrcaTorch light and want either a replacement cell or a charged spare for back to back dives, night dives and travel. Because the charging port is on the battery itself, you only need a USB-C cable and any USB power source, which keeps a travel kit small and removes the need to carry a dedicated charging cradle.

Compatibility and sizing

Frequently Asked Questions
Do I need a separate charger for the OrcaTorch 21700 battery?
No. The USB-C charging port is built into the battery itself, so you charge it with the included USB-C cable from any USB power source.

Which OrcaTorch dive lights use this 21700 battery?
OrcaTorch lists this 21700 USB-C 5000mAh battery for the D700 and D710, and the official OrcaTorch store also lists the DC710, ZD710 MK2, D710V MK2 and D720. The OrcaTorch Orca7 uses the same cell and ships with two of them plus one USB-C cable. Contact us if you want your specific light confirmed before ordering.
