18650 Battery Chargers: I am preparing this article to help you choose an 18650 battery charger, but I can’t stop myself from saying that these batteries are the soul of all DIY makers. These batteries are powerful, efficient, reliable and easy to use.
18650 is a lithium-ion rechargeable battery, that is popular in many DIY projects and is an excellent choice for powering a wide range of electronic devices. They are small, lightweight, and have a high energy storage capacity, making them ideal for powering small electronics.
These 18650-cell batteries are also highly efficient, which means they can last longer than other types of batteries. They are reasonably priced, making them an appealing option for do-it-yourself projects. However, the efficiency, durability, and long life of these cells can be achieved by properly charging and discharging them, and that’s why we prepared a list of the best 18650 Battery Chargers.
Best 18650 Battery Chargers on Amazon
Here are the 10 best 18650 Battery Chargers available on Amazon.in. You can buy them to charge these cells without any worry.
1. NITECORE New i4 Battery Charger
NiteCore’s new i4 Intellicharger is an improved multipurpose battery charger with a solid build and even claims to be made of fireproof materials. A wide range of Li-ion (Lithium-ion) types including IMR (Lithium-manganese) and LiFePO4 (lithium iron phosphate) cells can be charged in several voltages using the device, including NiCD (Ni-Cad) or NiMH (Nickel Metal Hydride) cells in sizes AAA, AA, C, and D.
In addition to 9–12VDC, this device can also be powered by your 110/120/240 wall outlet. With the i4, you can charge up to four batteries at once, and each cell can be charged independently. It is FCC, CEC, CE, and RoHS certified. Furthermore, you can charge a mix of D and smaller cells
NITECORE’s new i4 battery charger features four columns of four LEDs, one red and three green. If a cell is being charged or tested below it, a green LED will flash. Among the cells, one shows 30%, two shows 80%, and three shows 100%. If there are two greens on a steady means test, all three greens indicate that the battery is fully charged. However, four LEDs flashing at once indicate rejection of the cell.
Features
- 100% Charging Acceleration in comparison to i4
- Uses Active Current Distribution Technology
