Nightstick TAC-560XL
Brightest Tactical Flashlight in Its Class
The multi-function rechargeable light that retailers list as the Nightstick 800. Identify it by the TAC-560XL model number rather than the lumen figure, because that is what the battery part number is tied to.

Buying the Nightstick 800 replacement battery by part number
Retailers list this light as an 800-lumen model, but Nightstick publishes 1,000 lumens on High for the TAC-560XL, alongside 2 hours of run time and 208 m of throw. So the part number is the reliable identifier here, because output figures drift between revisions while the model number does not.
Four checks that stop you buying the wrong cell
A listing that says ‘fits Nightstick tactical flashlights’ is telling you nothing. 560-BATT is a specific pack with specific terminals.
The model number is printed on the body. Confirm it reads TAC-560XL before ordering, because Nightstick’s TAC-500 and TAC-600 series packs are not interchangeable.
Protected lithium packs are a common counterfeit, and a bad cell in a sealed light is a fire risk rather than an inconvenience.
The carrier shipped with the light and turns two primaries into a working flashlight while a replacement pack is in transit.
The CR123A backup already in the box
The TAC-560XL also runs on two CR123A primaries through a carrier that ships with the light. That is your answer on a night when the pack is flat and no replacement has arrived. A full charge takes 4 hours. Nightstick’s specification page lists the part number and every figure quoted here, and our first-time buyer’s checklist covers what else to weigh in a rechargeable light.
Nightstick 800 batteries: common questions
What is the part number for the Nightstick 800 replacement battery?
560-BATT. That is Nightstick’s replacement lithium-ion pack for the TAC-560XL, which is the model retailers sell as the Nightstick 800.
Why does my light say TAC-560XL and not Nightstick 800?
Because Nightstick 800 is a retail name and TAC-560XL is the catalog model. Nightstick publishes 1,000 lumens on High for it, so the lumen figure in the listing is not a reliable way to identify your light.
Can I use a generic 18650 cell instead?
Not safely. The 560-BATT is a specific pack rather than a bare cell, and generic lithium cells sold as a universal fit are a common source of both poor contact and counterfeit protection circuits.
What do I do while I wait for the replacement?
Run it on two CR123A primaries using the carrier that came with the light. Output and run time drop compared with the rechargeable pack, but the light works.
How long does a full charge take?
About four hours from flat, in the dock supplied with the light.
Is the light itself still covered if the battery dies?
Nightstick covers the TAC-560XL with a limited lifetime warranty, though consumable parts like a rechargeable pack are normally treated as wear items rather than defects.
Order the 560-BATT, and keep the carrier
- 560-BATT is the replacement pack for the TAC-560XL
- The retail name Nightstick 800 is not the catalog model number
- Two CR123A primaries run it through the included carrier
- Four hours to a full charge from flat
There is a specific answer to this question and it is 560-BATT, the pack Nightstick lists for the TAC-560XL. Order it by part number from a dealer rather than by description from a marketplace, and keep the CR123A carrier that came in the box so a flat pack never costs you the light.
