Advantages of LiMnO2 (vs. LiSOCl2):
- Generally safer with better thermal stability.
- Lower cost.
- Less noticeable voltage delay/passivation effect.
- Often, better pulse discharge capability (depending on construction).
-
Disadvantages of LiMnO2 (vs. LiSOCl2):
- Lower energy density (less capacity for the size/weight).
- Lower nominal voltage (3.0V vs. 3.6V).
- Less stable/flat discharge voltage curve.
- Reduced performance at extremely low temperatures compared to LiSOCl2.
No, you cannot. This is a common point of confusion, but a CR2 and a CR123A battery are not interchangeable. While both are 3V lithium primary batteries, they have different physical dimensions. A CR2 is shorter and has a slightly smaller diameter than a CR123A, so it will not fit correctly in a device designed for a CR123A. Always use the exact battery type specified by your device manufacturer.
While generally safe when used correctly, proper handling is crucial. To ensure safety, you should:
- Never try to recharge the battery.
- Do not short-circuit the terminals.
- Avoid puncturing, crushing, or disassembling the cell.
- Keep it away from open flames and extreme heat beyond its specified operating temperature.
- Dispose of used or damaged batteries properly according to local regulations for lithium batteries.
No, the CR2 is a primary (non-rechargeable) battery. It is designed for single use only, and attempting to recharge it is extremely dangerous. Recharging can lead to severe safety hazards, including internal short-circuits, leakage, overheating, rupture, or fire. Always replace a depleted CR2 battery with a new one.
