Cause Backup Battery Charger Explodes, Causes Fire and Prevention

Rechargeable backup batteries are becoming more and more popular in everyday life, but if used in the wrong way can cause explosion, even human damage. Therefore, users need to know why the battery clean up the explosion prevention and how to prevent it from the unfortunate accidents that can happen.

Poor battery charging quality

Overall, the backup charger is a collection of rechargeable batteries and is often used by reputable manufacturers using high-end Lithium-ion and Lithium-Polymer batteries. However, to reduce costs and increase profits, many manufacturers use poor quality materials and components (cheap Lithium-ion batteries or recycled batteries), which makes it easier to charge a backup battery.

To ensure safety, you should choose reputable backup battery chargers (despite higher prices).

Circuit design is not good

In addition to the quality of the rechargeable battery is not guaranteed, the poor circuit board design is also a cause that can cause backup charger to explode. Circuit board affects many factors, related to the performance and safety of backup batteries.

If designed well, cases such as overvoltage, overheating or short circuit on the charger will not occur and vice versa circuit design that does not conform to battery safety standards may increase the risk of explosion.

Currently, reputable manufacturers have integrated chips to automatically disconnect the current when fully charged. But with cheap batteries of 200,000 - 300,000 dong, there are not many safety features.

Improper use of backup charger

Improper use such as letting the device in the environment have a high temperature or humidity. is the cause of many explosion-proof rechargeable chargers.
