A photo of the inner workings of a typical laptop computer shows a risky, swollen battery that needs attention.

The lithium ion batteries that power our laptops and other handheld electronic devices are a consumable and won’t last forever. Keep an eye on laptops, tablets, mobile phones, and other devices for signs of a swollen battery. 

Swollen batteries can catch fire or explode; therefore, you must take action immediately! Turn off the device and unplug it. Do not continue to charge it under any circumstances. Do not attempt to remove the battery, as there are many safety concerns involved.

Convenient appliances over 600W must be plugged directly into a hardwired floor or wall outlet. These include most coffee makers, hot water heaters, and microwaves. Do not plug these devices into a power strip.

All electrical utilization equipment greater than 50 volts must have a proper NRTL listing. If you are unsure if your device is listed, please contact your Division Safety Coordinator or Electrical Safety Advocate/Officer.

Marc has provided extensive support within the Computing Sciences Area, as well as to the overall LBNL community, to establish a safe process for the handling of lithium ion batteries. His contributions include development and communication of training materials, education of safe handling practices for both end users and support staff, removal of swollen batteries so they can safely be disposed of, and hazard evaluation of laptops and cell phones. He will continue to provide support until the Lab develops a formal policy on this matter.

Integrated Safety Management (ISM) is the Department of Energy’s framework for how we protect ourselves and each other while pursuing the Lab’s mission.  With the ISM Guiding Principles as its foundation, ISM systematically integrates safety into management and work practices at all levels.
