In our daily life, some of us have the experience that when we forget to take out a battery of flashlight/e-cig and place it for a long time, we will notice that the batteries won’t work and can’t be charged again. If you use high drain batteries for your electronic cigarettes, you may notice that your new batteries also can’t be charged sometimes when we overuse it. The reason behind that is because your batteries are over discharged and the battery voltage is too low. Misuse of batteries can also lead to over discharge.
Numerous examples show that the batteries are easy to be over discharged which mean numerous batteries are thrown away every year. It will be a huge waste and bad for our environment. People may think it’s impossible to reuse the over discharge batteries. Before XTAR chargers came out, no chargers could do that. We turned impossible to possible and invented a technology that can revive the over discharge batteries called 0V activation function.
The reason the over discharge batteries can’t be charged by normal chargers is that the battery voltage is too low and can’t be detected. With XTAR battery chargers, the battery can be detected and charged again. For other over discharge batteries, if the batteries are not bad, can also be revived and charged by XTAR chargers.
It's dangerous if you over discharge your batteries.
