Once you have made the decision to save money and use rechargeable batteries, you will need to pick and efficient and reliable charger, if the batteries do not come with one already. Choosing the batteries is often about saving money and about the convenience, so the charger should fit the same bill too.

Follow this guide to help you buy the best 18650 battery charger and you will enjoy perfectly effective batteries without issue for longer.

What to Look for in 18650 Battery Chargers

One of the biggest factors in determining which charger would be best is to consider the amount of time it takes for the battery to be fully charged. There are chargers on the market that can recharge a battery in less than an hour. While this seems like a good feature to have, these more powerful chargers need to be carefully watched as the battery cannot be left to charge for any longer or there will be damage done. A faster charging time is certainly convenient but it can wear the battery and reduce the number of charges that it will take overall and thus reduce its life.

It is not uncommon for even the best 18650 battery charger to take several hours to completely recharge the battery from dead. These slower options will not damage the battery and are often less expensive. Determining whether value or convenience is more important will determine the charge time that best suits your needs.

Deciding Between the 18650 Battery Charger Options

  • Charging Slots. The number of batteries that you can charge at once depends on how you use the batteries. If you simply rotate a few pairs through constant use then you only need enough space to charge a few, but if you have multiple uses then one with 4 or 6 spaces would be best.
  • Universal. There are universal battery chargers and ones that have been specifically made to only suit the 18650 batteries. If you have more than one kind of rechargeable battery than a universal option would be better but the more specific charger is healthier for the battery that it has been made for.
  • Smart or Simple. A simple charger completes the charging of the battery and will only be turned off or adjusted when you manipulate the systems. A smart charger will monitor the battery itself and will often have a screen to indicate the state of the battery being charged. The simple chargers are less expensive and get the job done while the smart ones cost more but may help you get the most out of the batteries.
