Summary: The headlamp is worn on the head and is very practical for outdoor use. Headlamps commonly used today are generally rechargeable. The specific charging time depends on the battery capacity of the headlamp and the charging current of the charger. the size, it will take about 6 hours to charge normally. If it fails to charge, you can check the charging hole, charging ejector pin, charging cable and internal wires to find out the cause of the fault and repair it. Let's learn how to fix a headlight that won't charge. 1. It is best to charge the headlamp for a few hours.
The headlamp is a lamp worn on the head. As a lighting tool, its main function is to free your hands and is suitable for walking outdoors. night and camping when used.
Generally used headlamps can berecharged again. Charging takes several hours. It mainly depends on the battery capacity of the headlamp and the charging current of the charger. Generally, the battery capacity of 18650 lithium headlamp. The battery is 2400 mAh. If the charging current of the charger is 500-600mA, it can be fully charged in 4-6 hours.
2. How to fix the headlight not charging issue
When charging the headlight, sometimes the headlight cannot be charged. The reasons why the lighthouse cannot be charged are: It exists. several. You can first check the cause of the fault and then repair it:
1. Check if there is thick flying dust or debris in the charging hole, or the charging eject pin is not in the center and cannot make normal contact. Just clean it.
2. If it is not the problem above, check if it isproblem with the charging cable and use another charging cable to charge.
3. If the charging cable still cannot be charged after changing the charging cable, it may be a battery problem. Remove the charging tail cover and check if the internal wires have fallen out.
If none of the above methods can solve the problem, you can only go to the dealership to report it for repair or replace it with a new headlight.
3. What type of battery is used in headlights
There are generally three types of batteries used in headlights:
1. most commonly used battery. Its electrical energy is higher than that of lead-acid batteries, but it cannot be recharged and only has 10-20% power when at low temperatures. The voltage will be significantly reduced when used.
2. Battery nickel-cadmium: A headlamp using this battery can be charged thousands of times. It cannot be compared to the electrical energy stored in alkaline batteries. charged at low temperature. With 70% power, it is best to carry a high energy battery while climbing.
3. Lithium battery: It has 2 times the energy of ordinary batteries. It can still be used normally at low temperatures. Its voltage can be kept constant at high altitude, but its price is high. is relatively high.
