Reasons for using lithium batteries (lithium iron phosphate batteries) instead of lead-acid batteries
1. Lithium iron phosphate batteries and lead-acid batteries: cycle times
The cycle times of the battery means that the battery is completely discharged, and then recharged to a fully charged state for a cycle, lithium iron phosphate batteries can reach up to 6,000 cycles, while the lead-acid batteries for 200 to 500 cycles, sealed lead-acid batteries for 1,000 to 1,200 cycles, which means that the lithium iron phosphate batteries can be used for 10 years or so, the ordinary lead-acid batteries for about 2 years only! Sealed lead-acid batteries have a lifespan of about 4 years, so lithium iron phosphate batteries instead of lead-acid batteries have a longer lifespan and can be used for a long time.
2. Lithium iron phosphate and lead-acid batteries: depth of discharge (DOD)
Depth of discharge refers to the percentage of the rated capacity from the battery using electricity, lithium iron phosphate battery depth of discharge is 100%, but in our use of the process is best to use the depth of discharge of 80% of the electricity, will not shrink the service life of the battery, so that the battery performance to maintain the best. Ordinary lead-acid batteries have a depth of discharge of about 40%, medium deep cycle lead-acid batteries have a depth of discharge of about 60%, and deep cycle lead-acid batteries have a depth of discharge of about 80%, which means that then under the same volume, lithium iron phosphate batteries have a greater capacity to store and release more electricity, and replacing the lead-acid batteries with lithium iron phosphate batteries can improve efficiency.
3. Lithium iron phosphate and lead-acid batteries: charging time
Lithium iron phosphate battery charging time is faster than lead-acid batteries, in general, the charging time of lithium iron phosphate batteries for about 1 hour, lead-acid battery charging time for about 8 minutes, and lithium iron phosphate batteries will not appear overcharging phenomenon, lithium iron phosphate battery charger is a special charger, which can protect the battery from overcharging, temperature anomalies and other situations, lead-acid batteries, if overcharging, will lead to electrolyte If lead-acid battery is overcharged, it will cause the electrolyte to decompose into hydrogen and oxygen, which will cause the electrolyte level to drop and lead to an increase in the concentration of sulfuric acid, which will damage the life of the battery. So it is necessary to replace lead-acid batteries with lithium iron phosphate batteries.
4. Lithium iron phosphate and lead-acid batteries: discharge rate
Discharge rate is a measure of the speed of discharge, such as 100Ah battery and then 1 hour to complete the discharge is called 1C rate, in 5 hours after the discharge is called C/5 rate. Lead-acid batteries perform best at a rate between C/8 and C/12, while lithium iron phosphate batteries can handle a rate of C/1, which means that lithium iron phosphate batteries can be quickly discharged in a short period of time, which is more efficient than lead-acid batteries. However, care should be taken to protect the batteries when using them, and they should be operated at the rate recommended by the manufacturer in order to maintain the battery’s lifespan.
5. Lithium iron phosphate batteries and lead-acid batteries: voltage drop
Batteries will be the case of voltage drop, for example, when running high power loads, the voltage will be reduced, which will cause damage to the power equipment or batteries, lithium iron phosphate batteries have a high output voltage, stable output voltage, capable of high-current discharging, can effectively cope with high power loads, there will not be a sudden drop in voltage to ensure that the equipment operates well, lead-acid batteries in the operation of high-power loads, there will be a drop in voltage, poor operation, so lead iron phosphate battery will be the case of high power loads. Lead-acid batteries in the operation of high-power loads, there will be a drop in voltage, poor operation, so lithium iron phosphate batteries instead of lead-acid batteries can run better work.
6. Lithium iron phosphate and lead-acid batteries: safety
Lithium iron phosphate batteries in use will not be overcharged, over-discharge and short-circuit and other improper operation caused by combustion or explosion and other phenomena, mainly because of the chemical stability of lithium iron phosphate batteries, battery management system inside the battery, can prevent a variety of battery anomalies. Lead-acid batteries will discharge hydrogen and oxygen, electrode damage, electrolyte split, battery sulfation, sulfuric acid overflow (gel batteries and sealed batteries will not overflow), etc., which seriously affects our daily life, so the use of lithium iron phosphate batteries can greatly improve the safety and prolong the use of the battery time.
7. Lithium iron phosphate and lead-acid batteries: environmental protection
Although lead-acid batteries can do 100% recycling, but in the lead-acid batteries are dismantled, the electrolyte still contains lead, in the smelting process, the lead residue will also be produced in large quantities, improper treatment will pollute water and soil. Lithium iron phosphate battery is non-toxic, no pollution to the environment, does not contain any heavy metals and rare metals. So the use of lithium iron phosphate batteries instead of lead-acid batteries is more environmentally friendly, reducing pollution of the environment, and contributing to the human home.
8. Lithium iron phosphate batteries and lead-acid batteries: size
The same size and capacity of the battery, the volume of lithium iron phosphate battery is 2/3 of the volume of lead-acid batteries, the weight is 1/3 of the lead-acid batteries, which means that lithium iron phosphate batteries can save space and improve the overall utilization of space. And in some high-performance equipment, the weight of the equipment have requirements, lithium iron phosphate batteries are light weight, can be very good to meet the demand, reduce the overall weight of high-performance equipment, improve the performance of the equipment.
9. Lithium iron phosphate batteries and lead-acid batteries: temperature
High-temperature performance of lithium iron phosphate batteries can reach 350 ° C to 500 ° C peak electric heat, lithium iron phosphate battery operating temperature of -20 ° C to 60 ° C between the working temperature of lead-acid batteries for 0 ° C to 40 ° C between the working temperature of lead-acid batteries in the temperature below 0 ° C, the range of capacity will also decline in the -20 ° C, the capacity of the battery is only about 50% of the working temperature of lithium iron phosphate battery More extensive, can be applied to a variety of places, with lithium iron phosphate batteries instead of lead-acid batteries can get more battery capacity, the service life of the battery will also rise.
10. Lithium iron phosphate batteries and lead-acid batteries: price
The price of lithium iron phosphate batteries is higher than lead-acid batteries, lead-acid batteries have a long history of development, technology development is mature, so the use of low-cost, lithium iron phosphate batteries for the new batteries, the price will be relatively high, but we still choose lithium iron phosphate batteries instead of lead-acid batteries, mainly lithium iron phosphate batteries are far greater than the advantages of lead-acid batteries.
How to use lithium iron phosphate batteries instead of lead-acid batteries
The process of using lithium iron phosphate batteries instead of lead-acid batteries may be simple or complex, depending on the different applications, such as solar energy storage lead-acid batteries instead of lithium iron phosphate batteries, you need to consider the voltage of the battery, the solar controller and the inverter is compatible with the battery, etc., in the family’s back-up power supply to replace the lithium iron phosphate batteries only need to disconnect the positive and negative poles, and then connect it can be.
