Battery Safety

Battery Safety

Warning

• This device contains a built-in lithium-ion rechargeable battery with soft battery cells. Battery safety is the number one concern when repairing a device with a built-in lithium-ion battery.

• Only technicians with the knowledge, experience, and tools required to repair electronic devices should replace a battery.

• Improper battery replacement, improper handling of parts, failure to discharge the battery before repair, or failure to follow the provided instructions could cause battery overheating, swelling, venting, leaking, or a battery thermal event. These events could result in fire, injury, death, data loss, or damage to the device, parts, or other property.

• To avoid these potentially harmful events, follow the battery safety guidelines and work in a safety-focused workspace with the tools listed below. It’s important to be prepared for all possible outcomes.

How to set up a workspace for battery safety

Tools

• Clean, dry, untreated sand (8–10 cups)

• Sand container (wide-mouthed, quick pour, nonbreakable plastic container with a flip-top lid)

• Heat-resistant gloves

• Safety glasses with side shields

• ESD-safe cleaning solution

Workspaces used to repair Apple devices should meet the following criteria:

• Nonflammable and electrostatic discharge (ESD)-safe work bench

• At least 2 feet away from paper and other combustible materials

• Sand container within reach (2 feet) on both sides of the workspace, not above the workspace

• Adequate ventilation


iPhone SE (3rd generation) Battery Safety

Warning

How to handle a battery thermal event

A battery thermal event is a rapid chemical chain reaction that occurs inside a battery cell.

The energy stored in the battery is released suddenly, which can cause outgassing and fire.

A battery thermal event can be triggered by physical damage to the battery, improper replacement or repair, or temperatures outside the battery’s operating range.

Act immediately if you notice any of the following signs of a battery thermal event:

• The lithium-ion battery or a device that contains one begins to smoke or emit sparks or soot.

• The battery pouch suddenly and quickly puffs out.

• The lithium-ion battery or a device that contains one begins to emit hissing or popping sounds.

Don’t use water or an ABC or carbon dioxide fire extinguisher on a battery thermal event or a device that is undergoing one. Water and ABC or carbon dioxide fire extinguishers won’t stop the reaction.

Do smother the battery or device immediately with plenty of clean, dry sand. Dump the sand all at once. Timing is critical — the faster you pour all the sand, the sooner the reaction will be contained.

Do contact local fire authorities if further assistance is needed.

Do leave the room for 30 minutes after the reaction is contained. Ventilate the area. Don’t return until the area is clear of smoke.

Do wait 30 minutes before touching the device. Wear the heat-resistant gloves and safety glasses with side shields to remove the device from the sand.

Do wipe the affected area with water first. Then wipe the area with an ESD-safe cleaning solution.

Do dispose of the damaged battery or device (including any debris removed from the sand) according to local environmental laws and guidelines.



How to handle batteries

Battery Safety

Warning

Fully discharge the battery before you begin a repair. A discharged battery is less susceptible to a battery thermal event. If you can’t determine the battery level, don’t repair the device.

Perform the following steps to discharge the battery:

• Disconnect all external cables.

• Remove all cases and covers.

• Turn on the flashlight from the Lock Screen, in Control Center, or by asking Siri. Wait until the device has turned off and the flashlight is no longer illuminated.

Caution

The flashlight produces heat. Keep the iPhone in a well-ventilated area while the flashlight is illuminated.

Best practices

• To avoid noxious fumes or a battery thermal event, don’t puncture, strike, or crush a lithium-ion battery or a device that contains one.

• Keep your workspace clear of foreign objects and sharp materials.

• Be careful when using sharp tools near the battery.

• Don’t leave loose screws, extra screws, or small parts inside the device.

• Don’t use tools that conduct electricity.

• Don’t throw or drop the battery.

• Don’t expose the battery to excessive heat or sunlight, or temperatures outside the battery’s operating range.

• Handle and dispose of waste batteries in accordance with local laws and regulations.



Broken Glass

Broken Glass

Warning iPhone displays and some back covers are made of glass. The glass could break if the iPhone is dropped on a hard surface, receives a substantial impact, or is crushed, bent, or deformed.

Don’t attempt to remove chipped or cracked glass shards.

Tools

• Back protective cover

• Cut-resistant gloves

• Display protective cover
