Why MANLY Lithium Iron Phosphate Batteries can replace Lead-acid Batteries
Lead-acid batteries have many similarities with lithium iron phosphate batteries, and, some of the characteristics and application fields of the batteries themselves are almost the same. Next, let’s analyze the advantages and disadvantages of the similarities and differences between the two different batteries in detail.
MANLY LiFePO4 battery VS lead-acid battery
Comparing with the same voltage, same capacity, same size and same field of use
Environmental Protection
Lead-acid batteries contain high levels of lead, acid, and antimony, and are easily leaked during use and maintenance, causing pollution to humans and the surrounding environment
Lithium iron phosphate battery is a kind of green environmental protection material battery, harmless material, no pollution and harm to humans and the surrounding environment
Security
Lead-acid battery technology is quite mature and high safety, but it will cause fire and explosion under violent impact
Lithium iron phosphate batteries are inert material, due to the characteristics of the material itself, No explosion under intense impact, low damage to people and the surrounding environment, and high safety
Energy Density Ratio
The lithium iron phosphate battery is 3-4 times that of the lead-acid battery
Volume
Lithium iron phosphate battery is 3-4 times that of the lead-acid battery.
Service Life
Lead-acid batteries have a memory effect and cannot be charged and discharged at any time. The service life is 300-500 times, about 2 to 3 years.
Lithium iron phosphate battery has no memory effect and can be charged and discharged at any time. After the service life of 2000 times, the battery storage capacity is still more than 80%, up to 5000 times and above, and can be used for 10 to 15 years
Working Temperature
Lead-acid battery is suitable for use in the range of -20°C to -55°C due to the freezing of the electrolyte at low temperatures, , especially in winter when the temperature is low and cannot be used normally.
Lithium iron phosphate battery is suitable for -20℃-75℃, or even higher, and can still release 100% of the energy. The thermal peak of a lithium iron phosphate battery can reach 350℃-500℃. Lead-acid batteries are only 200°C
Self-discharge
Lead-acid battery self-discharges 15-30%, and the self-discharge is large. If it is not used for a long time, it will cause damage to the internal materials of the battery. The battery cannot be charged and discharged normally and cannot be used normally.
LiFePO4 battery self-discharge less than 3%
Price
Comparing the capacity with the same voltage, the price of lithium iron phosphate is much higher than that of lead-acid batteries. The price of lead-acid batteries is much higher than the price of lithium iron phosphate batteries in a comprehensive comparison of the same capacity and service life
Use and Maintenance
Lead-acid batteries require costs in both use and maintenance, and their costs increase accordingly
Lithium iron phosphate batteries do not require maintenance and can be used with normal charging, with high stability.
Charge and Discharge
Lead-acid battery has a small discharge rate and cannot be used for high current charging.
Lithium iron phosphate battery has strong power and can be quickly charged and discharged. It can be fully charged by more than 80% in 20 minutes and can be fully discharged in 15 minutes.
