Picking the Best 18650 Charger

There are hundreds of different battery chargers on the market that say they are the best 18650 battery charger. How are you supposed to determine which of these chargers is actually the one that you need?

You have to look at your battery consumption and usage and then compare the features of the chargers to determine which of them will supply you with fully charged batteries all of the time.

18650 NOT AA

You need to make certain that the battery charger you are purchasing is designed to charge the 18650 battery and not made to charge the standard AA battery. The 18650 battery is significantly different from the voltage found in the normal AA battery. There are smart chargers who are capable of determining the amount of voltage each battery placed in its charging ports needs and you can often charge both the typical AA and the 18650 batteries in these intelligent charging systems.

Check you Devices

You should check all of your devices that use batteries and determine whether they use AA, AAA, AAAA, C, D, 18650 or one of the other battery types. If you are uncertain whether the device you have needs a 18650 or an AA remember that both of these batteries are shaped alike but the 18650 is larger and measures 18mm x 65 mm where the typical AA measures 14mm x 50 mm.

Compare the Features of the Device

One way to make sure that you get the best charger for your battery needs is to compare the features on the charger. You may not ever need a charger that is DC capable, but another family may travel a great deal and a DC connector could be very useful to them.

Common Features found on 18650 Battery Chargers are:

  • Multiple charging ports
  • The ability to sense the voltage of batteries so the charger can charge more than one type of battery
  • Reverse polarity protection that stops you from connecting the battery incorrectly and causing damage to the battery
  • Automatic so the charger can stop the charging of a battery that has reached a full charge. This prevents damages that are caused when you overcharge a battery.
  • The LCD display screen that alerts you to how much of a charge each battery in each charging port has and the approximate amount of time it will take for a battery to reach a full charge
  • USB output ports so the device can be used to charge smartphones, tablets, and other electronic devices. This feature is very handy because the majority of people now carry some type of device that needs to be connected to a charger via a USB port.
  • Connection cables that allow you to hook the charger up in your vehicle so you can keep your batteries charged when you are traveling
  • Fire resistant materials that stop the charger from getting hot to the touch and prevents accidental fires. Older chargers often got very warm to the touch while they were in use and people often feared that they would start a fire in their homes. The fire retardant materials used to craft these items now assure you that they are safe to have in your home.
  • Bright LED lights that indicate whether a battery has a partial or a full charge. Some of the chargers have a three light system like a red light does with red meaning no charge, yellow meaning the battery is half of the way charged and green meaning the battery is fully charged and ready to use.
  • The ability to work properly in low heat situations or in high heat situations. The air temperature has an effect on devices like battery chargers. Many of these devices must be kept inside a home so the air temperature is regulated or they cannot do their job efficiently. If a charger is designed to withstand high or low temperatures they can be used in the garage or in the cellar of homes and they will still function properly.
