Frequently Asked Questions
Can I charge multiple battery types with a Nitecore charger?
Yes. Most Nitecore chargers support a wide range of battery sizes, including 18650, 20700, 21700, and other Li-ion cells. The charger can automatically identify the battery type and apply the correct charging mode.
Is it safe to leave my batteries in the charger overnight?
Yes, it is totally safe, because Nitecore chargers have overcharge protection. However, you should still avoid leaving batteries unattended for long periods. For your own safety, disconnect the charger once the batteries reach full capacity.
How long does it take to charge an 18650 battery on a Nitecore charger?
Charging time depends on the model and the battery’s capacity. On average, a 18650 battery can take about 2 to 4 hours using a standard Nitecore charger.
Why is my Nitecore charger showing an error or blinking light?
A blinking or error light means that the battery is inserted incorrectly, has low voltage, or is damaged. You need to remove the battery and reinsert it correctly to make it start working. If the issue continues, you should avoid using that battery.
Do Nitecore chargers stop charging automatically?
Yes. All modern Nitecore chargers stop charging your battery automatically once it is fully charged. This protects the cell and helps extend its lifespan.
