Description
This compatible battery is designed for the K40 (2019) smartphone. It replaces the internal battery and supplies the device with power. It helps with faults such as battery life that drops sharply, a phone that shuts down suddenly, or a battery that drains too quickly.
Before fitting, switch the phone off completely and disconnect the battery before touching the ribbon cables. Work on a clean surface at a moderate temperature, and avoid static electricity by discharging yourself on a metal object before touching components. Do not puncture the battery or bend it.
After fitting, carry out a few full charge and discharge cycles so the indicator regains a reliable reading. If the battery is swollen, do not use it. Check that the device starts and charges correctly before closing the casing.
Tips
- Disconnect the battery before touching the phone's ribbon cables
- Do not puncture or bend the lithium battery
- Swollen battery: stop using it and set it aside
- Carry out a few full charge cycles after fitting
- Work at a moderate temperature and avoid static electricity
Fitting
Fitting guide: work with the device switched off, disconnect the battery before touching any flex cable, keep the screws in order and test the part before closing up. A question before ordering? Write to us.
