SUPE 21700 USB-C Torch Battery is described in our source listing as a USB-C rechargeable 21700 battery listed for selected SUPE lights. Confirm your torch’s full model and version against the approved compatibility information. This is a different format from the 18650 option, even though the catalogue preserves a shared purchase link for both.

The archived description lists RD80 V2 and RD90 V2 among the compatible models. Treat that as a prompt for an exact manufacturer check, not a universal SUPE battery claim. The current seller option must specifically identify the 21700 cell you intend to buy.
Choose a replacement torch battery by the light’s complete model and version, not by the cell number alone. Length, protective electronics and charging arrangements can differ within a nominal format. Check the manufacturer’s compatibility list and the actual label on the battery you intend to replace before ordering.
Keep a clear distinction between a spare cell and a complete lighting system. A battery listing cannot establish the runtime or depth rating of your torch. Follow the battery and torch instructions for charging and transport, and ask the manufacturer when the listing groups several capacities or generations under one purchase link.
The original affiliate link is shared with another SUPE battery page, so the destination may offer several options. Confirm that the selected item is the approved 21700 part for your exact torch. A common purchase link does not make the 18650 and 21700 formats interchangeable or establish package contents.
No. Two batteries with the same nominal size can have different terminals, protection circuits or overall dimensions. Match the approved part to the exact torch model and version. If the original battery label or manual is unclear, obtain confirmation from the manufacturer before choosing a replacement.
Runtime depends on the torch, mode, battery condition and test method, so a capacity number alone cannot predict a useful dive duration. Check the manufacturer’s figures for the complete combination you plan to use. Keep your dive planning and backup arrangements separate from an unverified battery marketing claim.
Read the care guide, then follow the instructions for your exact equipment.
