Handle battery replacement and damaged batteries safely for A+
Short answer
A swollen or damaged lithium battery is a safety priority. The technician's first actions should prioritize safety over speed of repair. Steps include: stop using the device if safe; avoid puncturing or applying pressure; power down if possible and safe to do so; isolate the device in a fire-resistant container if available; consult organizational disposal procedures and manufacturer guidance; and use a battery-disposal facility or follow hazardous-material protocols.
Why it appears on the exam
- Given an image or description of a swollen battery, choose the safest first action among options such as "continue disassembly", "place in sealed plastic bag and throw away", or "power down if safe, isolate, and follow hazardous-material disposal procedures". - Given a removable battery replacement scenario, select the correct compatibility check and verification step after replacement.
Key concepts
Concept 1
Required terms
swollen battery: A lithium battery that has expanded due to internal gas generation and presents a puncture and fire hazard. lithium-ion: A common rechargeable battery chemistry for laptops and mobile devices that requires careful handling if damaged. swollen battery: expanded cell that is a hazard. lithium-ion: common battery chemistry requiring special handling.
Example
A tablet with a bulging back cover. Best action: avoid puncture, power down if safe, place the device on a noncombustible surface away from flammable materials, and escalate to proper disposal procedures rather than attempting an immediate in-field battery removal.

How Handle battery replacement and damaged batteries safely works
A swollen or damaged lithium battery is a safety priority. The technician's first actions should prioritize safety over speed of repair. Steps include: stop using the device if safe; avoid puncturing or applying pressure; power down if possible and safe to do so; isolate the device in a fire-resistant container if available; consult organizational disposal procedures and manufacturer guidance; and use a battery-disposal facility or follow hazardous-material protocols.
Example
A laptop with a user-removable battery that shows normal wear. Best action: power down, remove the battery, replace with a manufacturer-specified pack, and verify charging.
Concept 3
Common confusion
Students may prioritize quick removal of a battery without recognizing that attempting to pry a swollen cell can puncture it and cause fire. Another confusion is assuming household waste is acceptable for disposal; regulated disposal is required.
Example
A tablet with a bulging back cover. Best action: avoid puncture, power down if safe, place the device on a noncombustible surface away from flammable materials, and escalate to proper disposal procedures rather than attempting an immediate in-field battery removal.
