Many years ago, the Samsung Galaxy Note 7 became known when its batteries caught fire in various ways. There have been similar experiences, though isolated, since then. However, although high-performance batteries are not fully operational, most Li-ion batteries are safe.
The process inside the lithium-ion cell is complex, but as with any battery, there are bad and bad electrons. In lithium batteries, the worst is the lithium-carbon compound, and the best is cobalt oxide (although most batteries are derived from cobalt). These two types create a safe environment when operated and provide power to your equipment. When the action is difficult, you may have ears that melt in your ears. The factors that change the safe response to uncontrolled operation can be a number of factors: overheating, physical damage during use, physical damage during production, or the use of a faulty charger.
The three rules that have protected me (so far) from testing most batteries are:
- Avoid cheap cables, chargers, and external adapters.
- Make sure the batteries are not overheating (above 110 degrees).
- Frequently inspect batteries for damage.
Avoiding cheap adapters, cables, and chargers is very important. This is what causes problems. The chargers you see on Amazon for $ 20 cheaper than the competition? Unnecessary. They must have lowered the price by speeding up the blockade, dropping power outlets, and ignoring the basics of electrical safety. Price alone is not a guarantee of safety, either. Buy from reputable brands and brands.
Then there is the heat. Excess of it can lead to problems of any kind, in terms of output and security. Avoid heat, and listen to your batteries charge. If your device overheats when you order, this may be a sign of problems. Likewise, beware of swollen, swollen batteries, or other irritating buttons.
