4 Choose Branded 18650 Battery Charger
From consumers end, One of the important things we can do to avoid possible 18650 battery explosion is to buy high-quality battery charger?
The Easier way? Buy Branded chargers.
Some chargers that customer buy are made using inexpensive charging Chips/Designs and are not good enough in sending out accurate current, which can easily cause abnormal battery charging and even damage the battery. When choosing the charger, try to choose the top brand of 18650 lithium-ion battery charger, they have good quality control, and after-sales service, and thus can extend your battery life.
Branded 18650 battery charger has four basic protections: short-circuit protection, over-current protection, over-voltage protection, and battery reverse protection.
Over-Charge Protection: When the charger overcharges the lithium-ion battery, it needs to terminate the charging state immediately to prevent the possible internal pressure from rising since the internal battery temperature will rise if the battery is charged full already.
For this reason, It’s also suggested that a protection IC on the BMS of the battery is required to monitor the battery voltage. When it reaches the battery overcharge voltage, it activates the overcharge protection function and stops charging.
Over-Discharge Protection: In order to prevent the over-discharge status of the lithium-ion battery, when the lithium-ion battery voltage is lower than its over-discharge voltage detection point, over-discharge protection is activated, the discharge is stopped, and the battery is maintained in a low quiescent current standby mode.
Over-Current and Short-circuit Protection: When the lithium-ion battery discharge current is too large or a short circuit condition occurs, the protection device will activate the over-current protection function.
For lithium batteries, the reason for the explosion will be understandable, after all, in the past, the stability of the grass will not be so severe, but the 18650 as a very high-performance lithium battery, its application is certainly Will become more and more extensive, after all, in terms of such indispensable batteries, 18650 lithium battery is the best choice.
