Battery chargers are basic and simple pieces of technology. For the most part they come equipped with vents, an LED display screen, indicator lights, charging bays, or slots, and positive and negative terminals.

While they are indeed simple to understand and use, we have decided to include this handy, brief buyers guide just in case you may have questions regarding their purchase. Please do not think you can safely charge your Lithium-ion 18650 battery using a conventional charger. Choose one specifically made to charger 18650 Lithium-ion batteries only.

What Type of Batteries Do You Need it For?

This might sound elementary, but you really do need to double check to see if the charger can handle the batteries you need to charge. For instance, if you notice in our review above, there are some that can handle AA, AAA, AAAA size batteries, while others cannot. If you require a charger for lithium ion 18650 batteries, consider if you or another member of your household could use a charger that also handles the other type. Remember there are 3 kinds of 18650 batteries: IMR18650 Lithium Manganese Rechargeable, INR18650 Lithium Manganese Nickel Rechargeable, and ICR18650 Li-Cobalt Rechargeable

Smartphones and Other Devices

What about the added benefit of charging up your smartphones and other devices, such as your iPad or MP3? Well, if this is a concern for you, take a look and make certain that your charger of choice comes with 1 or more USB output ports.

Bays

Bays, or slots are where you’ll insert your battery to charge it. Some battery chargers have 2 bays, while others have 4. It’s also a very good idea to make certain that your battery charger is made from durable, ABS plastic with the appropriate venting to help keep it cool.

Is it ‘Smart’?

Most definitely, you should choose onlyl choose a ‘smart’ battery charger for Lithium-ion 18650 batteries. A smart battery charger will be able to monitor the charging process which guards against over heating, over charging, and reverse polarity protection, preventing your 18650 battery from exploding due to being over charged. These types of chargers will sense the type of battery inserted, and automatically provide the proper current (CC, CV, dv/dt), without you so much as pressing a button. Even though smart battery chargers do their job on their own, it cannot hurt to know how to calculate charging time:

  • Capacity(mAh) / Current (mA) = Total Time Charging
  • So, if your 18650 battery has 3500mAh and the current is 500mA:
  • 3500mAh / 500mA = 7 hours Charging Time.

Conclusion

First and foremost, let us remind you that the Lithium-ion 18650 is most definitely not a AA battery. Even though they are cylindrical in form and just a bit larger and fatter than AA’s, they are an entirely different type of battery. You’ll usually find the 18650 battery nestled snuggly powering your laptop or fueling your laser pointer, or some digital cameras.

They are rechargeable, but must only used a battery charger which is built to handle the job, or an explosion may occur. It may seem daunting when you go and search for a charger, but really, its a simple affair.
