Capacity is measured in milliampere per hour (mAh). Usually, people tend to choose a battery with the highest capacity, however, capacity comes at the cost of current rating (CDR). So you often have to choose between a high capacity battery OR a high current battery.
Continuous Discharge Rating (CDR):
The maximum current at which the battery can be discharged continuously and safely as per manufacturer testing without damaging the battery. Pushing a battery beyond its limits will greatly increase the risk of battery failure.
You should consider choosing a battery with a higher CDR rating, this is the most important element to consider when choosing a battery for a vape device. You need to know how much current the device requires before choosing your battery. If you choose a battery with a current rating less than what you need, you will notice the battery overheating as it is working beyond its ability to keep up.
Pulse Discharge Rating (Pulse):
The maximum current at which the battery can be discharged for a short period of time without damaging the battery or reducing its capacity.
Best Operating Temperature:
Lithium-ion batteries age at an accelerated rate below 0°C or above 45°C. If you are running your batteries hot, this will certainly cause premature ageing.
If your battery is consistently reaching a high temperature and getting hot, this is a warning sign that the battery is being pushed too hard. A battery that is consistently rising above 45°C will certainly cause premature ageing. They can also be dangerous as the high-temperature lithium-ion battery has a potential risk of venting and/or bursting.
Discharging and Charging:
To get the max life from your battery, we recommend keeping it within a range of 3.0V – 4.0V. Also, it’s highly recommended to use a good external charger for charging rather than charging the batteries inside the device.
Always make sure your charging device automatically turns off when charging is complete. It is also recommended to remove the batteries from the charger once charging is completed.
