Important Battery Information

First-Time Use:
For optimal performance, condition your new battery properly:

• New Lithium Ion batteries achieve full performance and longevity after 2 to 3 complete charge and discharge cycles

• After these initial cycles, the battery will be fully conditioned and ready for normal use

Battery Calibration:
For the phone's software to accurately read the new battery's capacity, follow this procedure:

1. After installation, charge the battery to 100% and continue charging for at least 2 more hours

2. Use the device until it shuts off due to low battery

3. Charge it to 100% uninterrupted

4. This helps the phone's software accurately read the new battery's capacity

Storage and Care:

• Do not expose the battery to flame or excessive heat 

• Keep the battery dry and avoid exposure to water or other liquids 

• Discontinue use immediately if you notice any change in the battery, such as discoloration or deformation

• To maintain battery health, charge when the level drops to 15-25% rather than letting it drain completely to 0%

• Avoid extreme temperatures 

Swollen Battery Warning:
If your old battery is swollen, take appropriate safety measures. Handle with extreme caution and avoid applying pressure. Do not puncture, deform, heat, or throw batteries into fire .

Proper Disposal:
Lithium-Ion batteries should never be incinerated or thrown into household trash . Always recycle old batteries through authorised electronic waste recycling centres.

Installation Information

This is an intermediate-level repair requiring careful attention. The Samsung Galaxy A40 features a non-removable battery design, which means professional-grade tools and techniques are necessary for safe removal of the old battery .

Some high-quality battery kits include a complete set of repair tools to assist with the replacement :

• Opening tools

• Adhesive strips

• Spudger

• Suction cup

Important Safety Precautions:

• Professional installation by a qualified technician is strongly recommended

• Ensure the device is turned off before installation 

• Never puncture, deform, heat, or throw batteries into fire

• If the battery is swollen, handle with extreme care and avoid applying pressure

• Use only plastic tools when working near the battery—metal tools can puncture the battery and cause a fire or explosion

• Disconnect the battery before attempting any repair

• Use ESD (electrostatic discharge) protection

• Keep defective batteries away from children and pets immediately

• Properly dispose of old batteries at an authorised electronic waste recycling centre

THE REPAIR PLUS strongly recommends having this component installed by a qualified technician with experience in smartphone repairs. We are not responsible for any damage caused during installation.
