The battery charger is almost as important in most homes as your phones. Most of the things we use at home and in the office use a battery to provide some of its energy. From laptops, toys, can openers, laptops, speakers, etc., we can rely on the battery power to make your life easy and more enjoyable.
After we get a suitable battery charger, how do you charger your battery properly? Proper charging methods can prolong battery life, and you can click here for further reading: How long does it take to charge 18650 battery, How to charge 18650 battery.
How to charge 18650 battery?
Purchasing a rechargeable battery and a charger for 18650 battery would save us money, a lot of tension and tears when the power is not available. Due to their high capacity, high voltage, long service life, good temperature performance and many other features and are accepted widely by the customers. Good chargers are needed for a 18650 rechargeable battery. Unless otherwise noted, most of the chargers have charge LEDs.
The charge LEDs work as follows: The green LED appears when the battery is not inserted in the charger, the red LED is displayed when charging, it lights to indicate that the green LED is does not turn on when the battery is inserted in the wrong direction. The charging time depends on the input voltage and battery capacity and can take between 2 and 5 hours to complete the charge. The 18650 battery charger has an AC input voltage of 110V to 240V, from 50Hz to 60Hz.
The 18650 battery charger protection features include: reverse battery polarity protection, overcurrent protection, and overvoltage protection, identify rechargeable battery automatically and short circuit protection. The charge of the rechargeable battery automatically begins and automatically switches to the protected state when you insert a non-rechargeable battery.
Can we charge 18650 battery without charger?
We are dependent on battery chargers for everything to work properly. But the question is what happens can we charge 18650 battery without charger. Yes, you can charge 18650 battery without charger. Using trickle charge will recharge most types of batteries. When you use a trickle charge, it provides a very weak electric current that the cells of the battery can absorb. Trickle charging takes a lot of time to recharge an exhausted battery, but it can be done safely and will not damage the battery you normally charge.
You need a regulator to apply a minimal charge, and fortunately, small incandescent lamps in light bulbs and decorative lamps are the perfect regulators for this task. You must connect a cable to the lamp you are using and the other end of the cable will be connected to a hot battery, such as the car's battery. The battery sends energy to the bulbs, the beam inside the lamps is heated and, when the temperature increases, it creates a resistance. The built-in resistor reduces or reduces the amount of current flowing through the lamp.
You can safely use the current coming out of the lamp to charge your battery. You will need to connect the equivalent of three small bulbs for Christmas at the same time to create a stream measuring half of the amplifier. You will need small alligator clips at the ends of the cables allowing you to connect to the positive and negative terminals of the battery you are charging. Remember this if you reverse the polarity of the battery while charging. (If you connect the negative terminal of the battery to a positive charge or the positive end of the battery to a negative charge), it will damage the battery and could cause injury.
If you do not have an alligator clip, you can simply remove the cables from the cables you are using, and then connect the cable end directly to the end of the battery. The battery terminals will contain a plus sign indicating the positive connection and a minus sign to indicate the negative connection. When using this method to charge the battery, you should stay with it even if you have alligator clips attached, and you must disconnect the battery after a few minutes. This sort of charging can be somewhat dangerous, so we must include some safety warnings.
Things to consider while charging 18650 battery
Car batteries, lawn mowers, transport vehicles, etc. may ignite with a small spark as they often make a mixture of hydrogen and highly flammable oxygen. A single spark can cause an explosion that sprays the sulfuric acid into your vehicle hood and causes mechanical damage to your engine, injury to your vehicle, and personal injury.
· Do not try to do this unless you wear goggles to protect your eyes from fumes and gases.
· If you charge the battery, you will not be able to charge it completely in this way without irreversibly damaging the battery.
· Do not leave the battery being charged in this way unattended for a period of time. There is a risk of fire and damage to the battery associated with sending this way, so do not walk away from the battery charged in this way.
· Instead of connecting your battery and headlights to your car's battery, you can plug it into cigarette lighter in your car, preventing the sulfuric acid from exploding or any damages to your car or your battery.
It is possible that if you try to charge a rechargeable battery without the proper charger, the battery will be damaged and you will have to buy a spare one.
18650 battery first charge
The capacity of the 18650 lithium battery is typically 1200 mAh to 3400 mAh, while the total battery capacity is only 800 mAh. 18650 can charge Li-ion packaging with any battery charger with the Li-ion battery charge function, in other words, the charge should end at 4.2V. You can charge individual cells with a fixed 4.2 volt power supply if you cannot get a charger. But lithium batteries require special chargers.
Charging lithium-ion batteries is simpler than nickel-based systems. The charging circuit is simple: it is easier to understand the current and voltage limits than the complex analysis of voltage signatures, which varies with the life of the battery. The charging procedure can be somewhat intermittent, the ions not needing saturation as in lead acid. This offers a great advantage for the storage of renewable energies, such as solar panels and wind turbines, which cannot always fully charge the battery. The lack of the trickle charge simplifies the process of charger.
Dongguan Large Electronics Co., Ltd (Large Power for short) has 17 years' expertise in customizing lithium ion battery pack and always adheres to the policy of maximum reliability and maximum safety. You can use Large Power products to power up and you will not be disappointed.
