2.Charging Voltage, Current and ChargingTime

The core of typical battery modules is 18650 lithium batteries. They are connected with serial and parallel connections. In case the device’s battery module is 10S (serial), you must select an output charger. Besides, the charger’s current size also affects the charging duration. For instance, a 20AH battery takes around four to five hours to charge with a 4A charger and about two to three hours with an 8A one.

3. Battery Type

Usually, battery chargers cannot identify the type of battery, whether LiNiCoMnO2, lead-acid or lithiumion. Accordingly, when you step out to buy a battery charger, you must first determine the type of battery in use to enable the power supply. It can prevent situations like the battery not charging or getting damaged. Additionally, the charger’s output voltage should also match the battery to avoid damage to the latter.

4. Charger Port

Another significant factor is to ensure that the specification of the DC jack matches the device to be charged so that it charges properly. Some lithium-ion battery charger manufacturers serve the needs of various battery management systems. They also provide various types of DC jacks to fulfil the usage requirements of various devices.
