18650 Battery Sleeve Pack

This pack contains twelve clear plastic sleeves sized for 18650 cells. Each sleeve measures 26 millimetres in diameter and 61.5 millimetres in length. They are designed to increase the diameter of an 18650 battery so it fits securely inside flashlights built for larger battery compartments. The sleeves also protect the battery casing from contact with the flashlight's inner wall.

Flashlight Compatibility Focus

These sleeves suit owners of flashlights that accept both 18650 cells and three-AAA carriers, where the single cell would otherwise sit loosely. They are not intended for lights with tight 18650-specific tubes or for adapting other battery chemistries or sizes. Buyers needing electrical conversion or voltage regulation should look elsewhere.

26 Millimetre Diameter

The critical specification is the 26 millimetre outer diameter, which determines whether the sleeved cell will seat properly in the flashlight bore. Verify the internal diameter of your light's battery tube against this figure before purchasing. The 61.5 millimetre length matches standard 18650 cell length.

Questions about this item

What diameter does the 26 mm sleeve adapt an 18650 battery to fit?

The sleeve increases the battery diameter to 26 mm (1.02 inch) so it sits securely in flashlights designed for 3×AAA holders.

What flashlight tube length will the 61.5 mm sleeve suit?

Each sleeve is 61.5 mm (2.42 inch) long, matching the length of a standard 18650 cell for full-length contact.

How do I install the sleeve without it slipping out?

Slide the clear plastic tube over the 18650 cell, then insert the assembly into the flashlight; the snug 26 mm fit stops the sleeve from falling out.
