Things to Consider When Buying

There are four major things to consider when you are looking for long lasting batteries  to use for your equipment.

  • First is the high capacity of the battery. This is important because it tells you how long your battery life is. The measurement for batteries is milliampere hours or mAh. Knowing the capacity of your battery will identify the number of milliamp available for use and for how long. For example, a 2500mAh battery can give you 2500mA draws in an hour. These numbers are not always 100% accurate, but it will give you an idea on how to compare the capacity of the best 18650 battery for you.
  • Second is the high current rating. It’s best to choose a battery that can safely generate the current that you need. This is to make sure that the battery doesn’t overheat. A good thing to remember is that you should never sacrifice high capacity for high current rating. Most people suggest a higher capacity and an average current rating for the perfect balance.  The best way to compare the current rating of batteries is by using the continuous discharge rating (CDR). This is the standard rating method used to rate a battery’s capability.
  • Next on the list is the high voltage quality when in use. This is simply the amount of current delivered to the coil to create a good amount of vapor. This quality depends on the kind of device the customer uses. There are mechanical users with devices that sends more current to the coil, and there are regular users whose batteries don’t work as much.
  • The last thing you want to check is the cool running temperature of the battery. This can determine the amount of damage that is done to your battery when in use. Just like most battery-operated equipment, if the temperature gets too high, your device might burst. The best battery is those that run at the lowest temperature possible. This way, you can customize your device’s power settings and coils.
