Beats Battery Safety

Warning

  • This device contains a built-in lithium-ion rechargeable battery. 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.

  • It is recommended to only install new batteries. Used battery cells can become damaged during the removal process.

  • 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

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

  • Nonflammable 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

How to handle a battery thermal event

Warning

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.

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 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

Warning

Before you begin a repair, if the device is functional, fully discharge the battery by playing audio with Bluetooth until it indicates the battery is low. A discharged battery is less susceptible to a battery thermal event. If you can’t determine the battery level, don’t repair the device.

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.
