Why Battery Damage Is Dangerous
Damaging a battery – even an ultra‑safe solid‑state battery – is not a good idea. As someone who has witnessed several battery fires (some deliberate, others unexpected), I have a healthy respect for how much energy we carry around in our pockets.
Common Causes of Battery Failures
- A bad batch of batteries or a manufacturing defect that damages a component.
- Use of incorrect or low‑quality components during assembly.
- Improper charging with the wrong charger or voltage.
User Behaviors That Increase Risk
- Throwing devices or subjecting them to physical shock.
- Exposing phones or tablets to water or high humidity.
- Charging devices in direct sunlight or leaving them in hot environments.
Built‑In Safety Features
Quality devices include safety mechanisms to protect against overheating, overcharging, deep discharge, short‑circuiting, and the use of an inappropriate charger. While these safeguards reduce risk, no system is completely foolproof.
Simple Rules to Prevent Fires and Explosions
- Use only the charger supplied by the manufacturer or a certified replacement.
- Avoid charging devices in extreme temperatures – keep them out of direct sun and away from heat sources.
- Do not expose batteries to water, moisture, or physical impact.
- Store devices in a cool, dry place when not in use.
- Monitor battery health regularly and replace any swollen or damaged cells promptly.
Seeing the Risks
Do not underestimate how quickly a lithium‑polymer battery can catch fire and how dangerous it can be. Below are a few videos showing just how bad it can get:
