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.
