Many years in the past, the (*12*) Galaxy Note 7 gained notoriety when its batteries caught fireplace in a sequence of incidents. There’s been a gentle stream of comparable, although remoted, incidents ever since. However, regardless of the high-profile protection of batteries gone incorrect, the overwhelming majority of Li-ion batteries are secure.
The chemical response that happens inside a lithium-ion cell is advanced, however as in any battery, there is a adverse and a constructive electrode. In lithium batteries, the adverse is a lithium-carbon compound, and the constructive is cobalt oxide (although many battery makers are shifting away from cobalt). These two compounds trigger a response that’s secure when managed and delivers power to your units. When the response will get uncontrolled although, you find yourself with earbuds melting in your ears. What adjustments a secure response to an uncontrolled response may be any variety of issues: extra warmth, bodily harm throughout use, bodily harm throughout manufacture, or utilizing the incorrect charger.
The three primary guidelines which have saved me secure (up to now) via testing dozens and dozens of batteries are:
- Avoid low-cost cords, chargers, and outlet adapters.
- Make positive batteries aren’t uncovered to extreme warmth (over 110 levels).
- Regularly examine batteries for indicators of harm.
Avoiding low-cost wall-outlet adapters, cords, and chargers is an important. These are your almost definitely supply of issues. Those chargers you see on Amazon for $20 cheaper than the competitors? Not value it. They in all probability acquired the worth down by skimping on insulation, leaving out power-management instruments, and ignoring the fundamentals {of electrical} security. Price alone is not any assure of security, both. Buy from respected corporations and manufacturers.
Then there’s warmth. Too a lot of it will possibly trigger all method of issues, each when it comes to discharge and when it comes to security. Avoid warmth, and take note of your batteries once they’re charging. If your system will get overly scorching when charging, this generally is a signal of issues. Similarly, watch out for any swollen, bulging, or in any other case misshapen batteries.
