Question about the power specs for the Aimpoint Comp M4

[WLJ]

The Comp M4 uses a AA battery which are typically 1.2v (rechargeable) to 1.8 (Lithium) in my experience.
From the power source specs off Aimpoint's website

Battery Type: 1.5 - 5.0 V alkaline / lithium, type AA
(rechargeable 1.2 V, acceptable voltage 1.2-5.0)

5.0v? Maybe a safety margin for a runaway battery?

Also possible they use the same circuitry for another model that uses a different battery entirely.

There's a military specific set of lithium bats and an adapter that we use for the M68 CCO. They are 5v.

I don't remember the NSNs off hand.

Why so high? The Comp M2 uses 1 3.0v battery while the M4 uses 1 1.5v. Adapter and battery compatibility with some other device that uses 5.0v?

5v ish?

I don't have one in front of me.  I just know that I have seen them.  They let you put 2 of the 1/3N lithiums in the CCO's that take those batteries.

There is a common. One that is just a spare battery holder, and the one I used back circa 2008 that put both batteries in the circuit.

I assume the CompM4's w8de power range is a leftover from that era.

Saw the battery doubler caps for sale for the Comp M2s and my next question was going to be are they merely storage for an extra battery or actually double the voltage but it looks like you answered both for that question already.
Appears the Comp M2 can run on either 3v or 6v.

The 5.0v thing on the Comp M4 led me to a rabbit hole of questions of why 5v?
