Red Indicator --- Charging
Green Indicator --- Full charged
(The blue light at the positive pole of the battery is up when charging, and goes off when the battery is full)
Red flashing --- Error
----The charger adopts a high-precision IC control system with battery identification and data reading capabilities. If other types of batteries are mistakenly charged, the charger will issue a flashing red light warning message.
Constant voltage output 1.5V Lithium-ion battery is a new generation of battery, so this Kratax charger is only suitable for this new type of battery, not for the traditional 3V-3.7V Li-ion battery and NiMh battery.
Q: Lithium-ion batteries and disposable batteries, which lasts longer in the flashlight?
A: The disposable battery has a long working time, but the lithium-ion battery can be recycled, the overall use time is longer, and the cost performance is higher.
The disposable battery can maintain high brightness due to the relatively high voltage during early operation. Then as the voltage decreases, the brightness will become lower and lower until the user replaces the battery.
The Lithium-ion battery voltage is constant, so the flashlight can maintain the highest brightness in the setting until the battery stops outputting, so the working time of a single lithium-ion battery will be about half less than that of a disposable battery.
Q: Why does it feel like a disposable battery discharges more power than a Li-ion battery?
A: Because the disposable battery does not need to be charged, it can use up all the power. Lithium-ion batteries require a secondary charge of the battery, so some of the power needs to be retained to maintain the battery's activity, So it will feel like the disposable battery releases more power.
Q: Why do lithium-ion batteries feel a little bigger than alkaline batteries?
A: The size of our battery is 44.5mm*10.5mm, because the lithium-ion battery is equipped with a protective plate, it may be 0.1~0.2mm larger than the length and diameter of a few alkaline batteries, mainly depends on What product to compare with.
