Incorrect Battery Status Display After Battery Replacement in EQUIL Pump

Reporting bugs

Environment:

Device: EQUIL pump

Power source: Replaceable battery

Description:
After replacing the battery in the EQUIL pump, the system does not immediately refresh the battery level. The device continues to report the previous battery charge value stored before the replacement. The correct battery level is updated only after several minutes of device operation.

This behavior may indicate that the battery level value is cached and not re-read from the hardware immediately after battery replacement or power cycle.

Steps to Reproduce:

Remove the battery from the EQUIL pump.

Insert a new, fully charged battery.

Power on the device.

Check the reported battery level.

Expected Behavior:
Battery level should be read from the hardware and updated immediately after battery insertion or device startup.

Actual Behavior:
Battery level initially reflects the previous battery state and updates to the correct value only after a delay (several minutes).

Impact:
User may incorrectly assume the new battery is discharged, leading to unnecessary battery replacements or support requests.

The issue names no source file or test; start by locating the EQUIL pump integration and its battery-status handling during startup and battery replacement. Reproduce the documented sequence with a replaced battery, then verify that the reported level immediately reflects the new hardware state rather than the previous value.
