Check out Aimpoint's battery page for the information: [url]http://www.aimpoint.com/products/batterier/batterier.htm[/url]

[B]Mk III, 2000, MPS and Laserdot LSR-2[/B]

* 123 or DL 123A (Duracell),
* BR2/3A (Panasonic)
* CR 123A (Varta),
* Ø16.9x34.5 mm, 1pc, 3V, Lithium
* PC1A 2 pcs, 1.5-volt each, Alkaline (See note above)

Note!
The above named Aimpoint sights originally used 2 1.5-volt mercury batteries. Due to pollution concerns, the mercury batteries have been legislated out of existence by many governments. The replacement battery is a single 3-volt lithium battery. The polarity of the lithium battery is opposite of the polarity of the older mercury batteries. So the new battery must be inserted in the opposite direction. Also there is a plastic coating on the outside of the battery, which must be removed before the battery is inserted into the battery compartment of Mk III sights.
