What is the difference between the XTAR charger L4 and BC4?
L4 lacks USB output, a transparent cover, and lights. But it features a hollow design, making it easier to remove the battery.
Can the XTAR L4 charge 3.6V lithium batteries?
The L4 charger cannot charge 3.2/3.6/3.7V lithium batteries. If such batteries are mistakenly inserted, the L4 charger will quickly flash a red light and will not charge them.
When using the L4 or L8 charger for 1.5V lithium batteries with LED indicator, how are the charger's LEDs and battery indicator lights coordinated during charging?
In charging, the LED light of the charger L4 or L8 will be in solid red, and the LED light of the battery will flashing. After fully charged, the LED light of the battery will turn off, and the LED light of the charger L4 or L8 will be in solid green.
What are the meanings of the different states of the LED indicator lights on the L4 charger?
After powering on, all channel red lights will be on for 1 second, then switch to steady green light (standby mode). Inserting battery shows slow flashing red light (0V activation/identification). Steady red light indicates normal charging. Rapid flashing red light indicates charging abnormalities. Steady green light indicates charging complete.
Which brands of batteries can be charged with L4?
XTAR L4 is compatible with AA/AAA NiMH batteries and the majority of 1.5V lithium batteries from various brands.
