• Bad merchants use poor quality batteries to pretend to be lithium batteries for sale

Many unscrupulous merchants will recycle batteries of very poor quality, and then refurbish the old batteries and sell them in the name of new batteries to obtain high profits. And these batteries will often have problems in the process of use, which will lead to accidents. These problem batteries have some common characteristics, that is, low cost, excessive impurities, and poor design technology.

• Short circuit with off-brand chargers

Poor quality chargers are often inferior materials that are not fireproof and do not meet national safety standards. Using a no-brand guarantee charger to charge the battery will cause the battery protection system to fail. It can lead to undercharging or overcharging. When the voltage reaches a certain level, if the lithium intercalation ability of the negative electrode is poor, lithium ions will be deposited and short-circuit the inside of the cell; if the lithium intercalation ability of the negative electrode is relatively strong, the solvent will be rapidly oxidized, and a lot of heat will cause the battery temperature Elevates and triggers more reactions, giving off more heat. If the stability of the cell is poor, the battery will burn or even explode.

• Household power strips cannot handle high power batteries

Each power strip has its maximum power tolerance range. If the user charges a charging device with excessive power, a short circuit will easily happen. Once a short circuit happens, it will heat up to a certain extent. Even worse, there will be an explosion.

The quality of the battery is related to the safety of the user’s life. A good lithium battery is not only safe and reliable but also extends the battery life. Conversely, a poor quality battery will bring devastating harm and bad experience to people. Choose a brand lithium battery, proper use and storage them for safety guarantee.
