Panasonic CR123 two-pack for flashlights
This pack contains two Panasonic CR123 lithium batteries intended for high-drain devices such as LED flashlights. They suit owners of lights that accept either a single 18650 cell or a pair of CR123 primaries. Users needing rechargeable cells or proprietary battery packs should look elsewhere.
Thermals noise and power in normal use
Primary lithium chemistry delivers stable voltage with minimal self-heating during the 2 to 3 hour high-mode runtime typical of a 300 lumen Cree XP-E light. No active cooling or fan noise is involved because the batteries are passive components. The cells add 136 grams combined weight to the flashlight.
What the bundled accessories change
The bundle pairs the batteries with an S02 flashlight body made from 6061-T6 aluminium measuring 145 millimetres long with a 25 millimetre body diameter. Five operating modes including strobe and SOS become available immediately. Builders who only want the cells without the light gain no advantage from this package.

Questions about this item
How do I install the two CR123 batteries in the S02 flashlight and which way should the positive ends face?
Unscrew the tail cap, insert both CR123 cells with the positive ends pointing toward the head, then tighten the cap until the threads seat fully; the tail‑cap button will not work if a cell is reversed.
When should I replace the CR123 cells and how can I tell they are depleted?
Replace them when the beam dims noticeably or the flashlight drops out of High mode after a short time; on High the pair typically lasts 2 to 3 hours before voltage falls too low.
What runtime limit appears first during continuous High‑mode use?
The 2 to 3 hour High‑mode runtime is the first limit; after that the cells can no longer sustain the 3 W draw and the light steps down or shuts off.
