How to charge lead-acid batteries and lithium iron phosphate batteries correctly?

Correct charging method for lead-acid batteries The most taboo of lead-acid batteries is to charge them when they are completely discharged. In this way, the battery life will be greatly reduced. 1. The lead-acid battery is charged when the power indicator shows the remaining one-third of the power. 2. The charging environment should be kept dry and tidy, and the charger should not be wrapped in plastic bags or plastic bottles, because the charger is easily burned when it is unable to breathe. 3. Try not to use fast charging for lead-acid batteries, if not necessary, do not use more than twice in a month. 4. Place the lead-acid battery charger in a fixed place, don't bump it, even if you carry it, you must fully consider the failure caused by bumps. 5. Use the standard charger to charge. 6. The most ideal charging time is when 60%~80% of the battery's power is consumed. 7. Prevent overcharging. Stop charging when the charger shows full charge. It can't be charged overnight or even a few days. Overcharging will cause the active material of the plate to harden and fall off, and cause water loss and battery deformation. Lead-acid batteries run in high-temperature seasons, and there is an important problem of overcharging. 8. It should be noted that the charger should be ventilated during the charging time, otherwise it will affect the life of the lead-acid battery charger and may also affect the charging state. Summary: Generally, the chargers for charging lead-acid batteries for electric vehicles use a three-stage charging mode. When 100% of the battery is used up, the charging time will be 8-10 hours, not more than 12 hours. The battery life will have an impact. It is best not to run out of electricity every time you use it. It is recommended to charge the electric vehicle when the electricity consumption is about 70%. The charging time is generally about 6 to 8 hours. If the mileage required for riding is relatively long, multiple chargers can be used, and the charger that is fully charged during the day uses an additional charger, and the original charger is used at night. Charging every day will make the battery in a cycle state, and the battery life will be prolonged. The memory benefit of lead-acid batteries is not so strong, and frequent discharge will have a great impact on battery life. The correct charging method of lithium iron phosphate battery 1. Constant current charging, that is, the current is constant, while the voltage of the lithium iron phosphate battery gradually increases with the charging process. According to the above specifications, it is generally charged with a current of 0.2C. When the battery voltage is close to the full voltage 4.2 At V, change the constant current charging to constant voltage charging. This process is about five hours. 2. Constant voltage charging, that is, the voltage is constant, and the current gradually decreases as the saturation of the cell deepens. According to the specification, when the current decreases to 0.01C or 10mA, the charging is considered to be terminated. After this process and the constant current charging time are added together, the total charging time should not exceed eight hours. 3. The temperature of the lithium iron phosphate battery during charging is preferably within 0-45°C. Such a temperature is more conducive to the activation of chemical properties in the lithium battery and makes the charging efficiency higher. 4. Regarding the charger of the lithium iron phosphate battery pack, it is best to use the special charger equipped by the manufacturer. Do not use other chargers of other models or unsuitable charging voltages at will. 5. After charging the lithium iron phosphate battery, try to prevent it from being placed on the charger for more than 10 hours. If it is not used for a long time, the mobile phone and the lithium battery should be separated. 6. The charger can only protect the terminal voltage of the entire battery pack. The balanced charging board ensures that each cell is overcharged and each cell is fully charged. The entire lithium iron phosphate battery cannot be stopped because one cell is fully charged. Pack charging. 7. When you get the lithium iron phosphate battery and want to use it formally, you must charge it, because the battery cannot be overfilled when the lithium battery is stored, and overfilling will cause severe capacity loss.
