The
MecArmy LIR10180 is protected, 100mAh. I don't understand why it is 3.7V instead of 3.6V, I think the protection circuit and the increased capacity compared to other 10180 means it is LiCo. I think that the claim of 3.7V must be a mistake. But doesn't LIR mean it is LiCo?
Apparently not, the
Klarus 10180 advertised as IMR, reads LIR right on the battery label.
Maybe LIR doesn't speak to specific chemistry, and simply means, ambiguously, "Lithium Ion Rechargeable."
The
JetBeam 10180 is unprotected, 3.7V, and only 70mAh, and if it is IMR or INR, it should be unprotected, 3.7V, and have less capacity than LiCo. If it was LiCo, I'd expect it to have more than 100mAh because protection circuits take up room, and this doesn't have one.
Anyone with knowledge of different Li-ion chemistries should be able to tell me how wrong I am to assume the JetBeam is IMR or INR based on these reasons.
Welll, the
Fenix 10180 is 3.6V, indicating LiCo chemistry, and unprotected, and only has 80mAh. Wonder why the capacity is so low when no room is taken up by a protection circuit.
