Please do not think you can safely charge your Lithium-ion 18650 battery using a conventional charger. Choose one specifically made to charge 18650 Lithium-ion batteries only.
Choose Compatible Type to Your Batteries

For instance, if you notice in our review above, there are some that can handle AA, AAA, AAAA size batteries, while others cannot.

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

The 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’?

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:
