The OrcaTorch 21700 USB Rechargeable Battery removes the one piece of kit divers most often forget: a separate charger.

Built with an integrated USB-C port, this 5000mAh cell charges directly from any standard USB cable, no dock, no charging bay, no cradle to misplace between trips. At 3.6V and 18WH capacity, it packs meaningfully more runtime than a standard 18650, which matters most on the second dive of the day when a depleted battery has already forced you onto a backup light once.

A full charge takes roughly 4 hours 30 minutes, and built-in overcharge and over-discharge protection circuits guard against the two failure modes that shorten a Li-ion cell's working life. That protection matters more underwater than most divers realise: a battery that fails mid-dive isn't just an inconvenience, it's the reason a backup light exists in the first place.

Compatibility runs across OrcaTorch's larger canister and video lights: D700, D710, D710V MK2, DC710, ZD710 MK2, and D720. Check your specific model against that list before ordering, since battery compartments aren't universal across OrcaTorch's range even within similar-looking housings.

For divers already invested in OrcaTorch's higher-output lights, this battery is less an upgrade than a maintenance item worth keeping a spare of, one dead cell shouldn't be the reason a dive gets cut short.

Compatible with: OrcaTorch D700, D710, D710V MK2, DC710, ZD710 MK2, D720.
