How Do I Choose the Best Camcorder Battery Charger?

The charging time is the time required to fully charge the capacitor. The charging time of electric vehicles and other vehicles commonly used in homes is often a concern of users. The correct charging method and reasonable charging time can help extend the service life of electric vehicles.

Through the analysis of the above example, we can see that under the condition that the battery capacity of device A is determined, the factors that affect the long charging time of the device mainly come from three aspects:

(1) The design of the motherboard itself, including the settings of the power management chip, the current limiting settings of the motherboard, etc. By reading the information of the power management chip, it is necessary to achieve reasonable control. It cannot be set too large or too small.

(2) The charging circuit problem. The charging circuit mentioned here is the path from the charger to the charging chip, including the physical connection line, PCB traces and various devices on the line. This impedance setting, device selection It must be reasonable. According to the demand current, a mismatch will cause the current to decrease.

(3) Charger problem, which refers to various charging interfaces, including the charger and the U-port of the host computer. The load capacity of different devices varies greatly. The theoretical calculation combined with the actual test, what is to be done is to ensure the rationality of various components on the charging path, thereby ensuring the charging time. ^[1]

1. Normal charging time is approximately equal to: battery capacity mAh ÷ charging current (600mA for this charger) × factor 1.2 = charging hours.

2. The charging time of each battery is different. After the charger's CHARGE indicator turns green, it indicates that the normal charging is completed.

3. The charger can micro-charge the battery for 1 hour after the normal charging is completed, so that the battery is fully charged. Full charging can allow you to use the battery for a longer time than under normal charging. (Even if the battery has not been fully charged, you can remove the battery from the charger at any time to use the battery)

Instructions for use:

A: According to the polarity direction of the battery to be charged and the charging polarity on the charger. Load the battery into the charger correctly.

B: Insert the power plug of the charger with the battery to be charged into the mains power supply.

C: When the power indicator (red light) on the charger is on, it means that the charger is charging the battery. When the battery is fully charged, the power indicator is green (or flashing). Please keep charging for 60 minutes. The charging effect is better.

D: Remove the charger and battery from the power socket. At this time, the battery can be used normally.

Note: When you use a new battery, keep the charging time for more than 10 hours in the first few times (don't care about the "battery is full" prompt when charging for 1-2 hours), and try to drain the battery as much as possible (showing "battery low "The next time you charge it again, the battery will be activated to the best state after several repetitions, and the camera / camcorder will also reach the longest standby time. In the future use, there is no such limitation, but it is best to Charge it for 2-4 hours to fully charge the battery. ^[2]

Pay attention to the following points when charging electric vehicles:

1. The battery cannot be recharged empty. If it is recharged after empty, the battery capacity will decrease by 2%.

2. If convenient, it can be recharged when 70% is used.

3. Charging must be sufficient, it is advisable to charge for 2 hours after changing the lamp. But never recharge for more than 12 hours

4. Normal charging can be based on the actual power consumption according to the power consumption. For example, when charging in the future, use the same power to exceed the normal charging time for too long. Power off in time and send the battery and charger to prevent the battery from being charged.

5. If it is not used for a long time, it is best to have it once in about 20 days. Do not store it at low voltage.

6. Don't use other people's charger to charge at will. For example, the voltage and the positive and negative poles of the interface are not the same, which will cause damage to the battery. How long is the best time to charge the battery of the electric car? The battery for electric vehicles is used up, not used up. You can see the importance of matching the charger with the battery and grasping the charging time. Here are the best ways to charge an electric vehicle battery.

The correct use of the charger only affects the feasibility and service life of the charger itself, and it also affects the battery life. When using the charger to charge the battery, please plug in the charger's output plug first, and then the input plug.

The charger needs to be protected from moisture and humidity during use, and placed in a well-ventilated place. There is a certain temperature rise when the charger is working. Please pay attention to heat dissipation. The charging time is usually 7-8 hours, depending on the battery usage status (for example: using an electric vehicle to discharge the battery by 30%, the charging time cannot be 7-8 Hours, you should stop charging after the charging indicator turns green for 1 hour. If you continue to charge, it will cause overcharging). When charging, the power indicator of the charger is red, and the charging indicator is also red. When fully charged, the charging indicator is green. Stop charging after 1-2 hours after the indicator light changes from red to green. When stopping charging, please unplug the charger's input plug first, and then unplug the charger's output plug. Under normal conditions, over-discharging and over-charging the battery is harmful. Therefore, it is necessary to charge frequently and not overcharge.

The life of a battery has a lot to do with its depth of discharge. Lead-acid batteries are particularly afraid of losing power. Charge the dead battery as soon as possible after use. For batteries that have not been used for a long time, the batteries should be recharged every 1 month to compensate for the loss of self-discharge power when the batteries are stored.

The charger is a relatively sophisticated electronic device, so care must be taken to prevent vibration during use. Try not to carry it with the vehicle. If you really want to carry it, pack the charger with vibration-damping materials and place it in the tool box on the car. Pay attention to rain and moisture. The electric vehicle battery network here reminds consumers to grasp the time to charge the electric vehicle battery in the daily use process, to develop good charging habits, will greatly extend the service life of the electric vehicle battery, and to purchase a charger for the battery, Don't overcharge the battery because it's cheap, but you'll lose more. ^[2]
