A few years in the past, the Samsung Galaxy Word 7 gained notoriety when its batteries caught hearth in a collection of incidents. There’s been a gradual stream of comparable, although remoted, incidents ever since. Nevertheless, regardless of the high-profile protection of batteries gone mistaken, 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 transferring away from cobalt). These two compounds trigger a response that’s secure when managed and delivers vitality to your gadgets. When the response will get uncontrolled although, you find yourself with earbuds melting in your ears. What modifications a secure response to an uncontrolled response might be any variety of issues: extra warmth, bodily injury throughout use, bodily injury throughout manufacture, or utilizing the mistaken charger.
The three primary guidelines which have saved me secure (to this point) by testing dozens and dozens of batteries are:
- Keep away from low cost cords, chargers, and outlet adapters.
- Ensure batteries aren’t uncovered to extreme warmth (over 110 levels Fahrenheit).
- Repeatedly examine batteries for indicators of harm.
Avoiding low cost wall-outlet adapters, cords, and chargers is a very powerful. These are your almost certainly supply of issues. These chargers you see on Amazon for $20 cheaper than the competitors? Not value it. They most likely received the worth down by skimping on insulation, leaving out power-management instruments, and ignoring the fundamentals {of electrical} security. Value alone is not any assure of security, both. Purchase from respected firms and types.
Then there’s warmth. An excessive amount of of it might trigger all method of issues, each by way of discharge and by way of security. Keep away from warmth, and take note of your batteries once they’re charging. In case your gadget will get overly scorching when charging, this could be a signal of issues. Equally, watch out for any swollen, bulging, or in any other case misshapen batteries.
