What are the correct charging methods for lead-acid batteries and lithium iron phosphate batteries?

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, and do not use more than twice within a month if it is not necessary. 4. The lead-acid battery charger should be placed in a fixed place, do not bump, even if you carry it, you must fully consider the failure caused by bumps. 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 is reduced 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 the 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. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
