RechargeableNo
Drain markingNot specified
Typical applications
- Watches
- remotes
- sensors
- memory backup
Replacement decision
Resolve the original marking to this profile, then confirm nominal voltage, chemistry, dimensions, polarity and any drain or terminal suffix. Capacity alone does not establish interchangeability.
Same-size batteries to review carefully
These profiles share the nominal physical envelope. They are not automatically equivalent.
