Coin-type Lithium Primary Batteries
Features
- Low self-discharge rate and long life.
Self-discharge : Approx. 1% per year at room temperature. - Usable over wide temperature range.
Operational temperature range
: -20°C to +60°C (-4°F to +140°F)
(CR-1/3N, 2CR-1/3N)
: -20°C to +70°C (-4°F to +158°)
(other models) - UL recognition (File No. MH13421)
Applications
- Electronic notebooks
- Electronic automobile keys (keyless entry)
- LED-related devices
- Memory backup power source
Other
- Available with secondary processing (multiple cells, tabs, connectors, etc) in accordance with use.
- Nickel-plated phosphor bronze or stainless steel should be used for battery contact terminal materials.
To ensure stable contact conditions, contact pressure of several newtons is recommended when attaching.
