Features:
Rechargeability
These battery packs are rechargeable, which is a major advantage over non - rechargeable batteries. They can be recharged hundreds or even thousands of times, depending on the quality of the battery and the charging conditions. This makes them a cost - effective solution in the long run. For example, in a cordless power tool, the ability to recharge the 18650 battery pack means that the user doesn't have to constantly buy new batteries, reducing waste and cost.
The recharge process is usually relatively simple. They can be charged using a dedicated Li - ion battery charger, which typically monitors the charging process to prevent over - charging and over - heating.
Voltage Characteristics
A single 18650 Li - ion battery typically has a nominal voltage of around 3.7V. Battery packs can be configured in series or parallel to achieve different voltage and capacity requirements. For example, two 18650 batteries in series can provide a 7.4V output, which is suitable for powering devices that require a higher voltage. In parallel configuration, the capacity is increased while the voltage remains the same as that of a single cell.
The voltage output of 18650 battery packs remains relatively stable during the discharge process, especially when compared to some other battery chemistries. This stability is crucial for the proper operation of electronic devices, as many components have specific voltage requirements.
