Correct charging method for lead-acid batteries
The worst thing you can do with lead-acid batteries is to completely discharge them before recharging them, as this will significantly reduce their lifespan.
1. Charge the lead-acid battery when the power indicator shows one-third of the power remaining.
2. Keep the charging environment dry and clean. Do not wrap the charger in plastic bags or plastic bottles, as it is very easy to burn out when the charger cannot breathe.
3. Avoid using fast charging for lead-acid batteries as much as possible; if not necessary, do not use it more than twice a month.
4. Keep lead-acid battery chargers in a fixed location and avoid bumps or knocks. Even when carrying them, take full account of the potential for malfunctions caused by jolting.
5. Use the included charger to charge.
6. The ideal time to charge is when the battery has consumed 60% to 80% of its charge.
7. Prevent overcharging. Stop charging when the charger indicates a full charge; do not leave it charging overnight or for several days. Overcharging will cause the active material on the plates to harden and detach, leading to water loss and battery deformation. Overcharging is a significant concern for lead-acid batteries operating in high-temperature seasons.
8. It is important to ensure that the charger is well-ventilated during charging, otherwise it will affect the lifespan of the lead-acid battery charger and may also affect the charging status.
In summary, most electric vehicle lead-acid battery chargers use a three-stage charging mode. When the battery is 100% depleted, the charging time will be around 8 to 10 hours. Do not exceed 12 hours, as this will affect the battery's lifespan. It is best not to use up all the battery every time you use it. It is recommended to charge the electric vehicle when the battery level is around 70%, and the charging time is generally around 6 to 8 hours.
If you need to cycle for a long distance, you can use multiple chargers. Use a supplementary charger for daytime top-ups and the original charger for nighttime charging. Daily charging keeps the battery in a cycle state, extending its lifespan. Lead-acid batteries don't have a strong memory effect, and frequent discharges will significantly impact their lifespan.
Correct charging method for lithium iron phosphate batteries
1. Constant current charging: The current is constant, while the voltage of the lithium iron phosphate battery gradually increases during the charging process. According to the specifications, it is generally charged at a current of 0.2C. When the battery voltage approaches the full charge voltage of 4.2V, the constant current charging is switched to constant voltage charging. This process takes about five hours.
2. Constant voltage charging: The voltage is constant, while the current gradually decreases as the cell saturation level increases. According to the specification, charging is considered to terminate when the current decreases to 0.01C (10mA). The total charging time, including this process and the constant current charging time, should not exceed eight hours.
3. The optimal charging temperature for lithium iron phosphate batteries is between 0-45℃. This temperature range is more conducive to the activation of the chemical properties within the lithium-ion battery, resulting in higher charging efficiency.
4. Regarding chargers for lithium iron phosphate battery packs, it is best to use the dedicated charger provided by the manufacturer. Do not use other models or chargers with incompatible charging voltages.
5. After the lithium iron phosphate battery is fully charged, try to avoid leaving it on the charger for more than 10 hours. If the phone will not be used for a long time, it should be separated from the lithium-ion battery.
6. The charger can only protect the terminal voltage of the entire battery pack. The balance charging board ensures that each cell is not overcharged and that each cell is fully charged. The charging of the entire lithium iron phosphate battery pack should not be stopped because one cell is fully charged.
