💡 Why do alkaline button cells lose capacity quickly inside chronograph modules during extended idle periods?
Finding a handy storage practice preserves internal chemistry for future use.
- Tight galvanic sealing stops sulfate crystals from forming on zinc anodes
- Consistent paste thickness maintains steady ion migration across cathode layers
- Optimized separator porosity balances rapid charge delivery with slow drain retention
- Uniform plating tolerances reduce contact resistance inside coin cell tracks
