What is the difference between lead-acid battery and lithium battery UPS

Lead-acid batteries are generally deep-charged and discharged within 300 times, have memory, and have a lifespan of about two years. And there is liquid in the lead-acid battery. After a period of consumption, if the battery is found to be hot or the charging time becomes short, it is necessary to replenish the liquid; UPS lithium battery has strong durability, slow consumption, more than 500 times of charging and discharging, and no memory. The general life span is 45 years. 2. In terms of volume and quality: the general UPS lead-acid battery weighs 1630 kg, which is relatively large; the lithium battery UPS is generally 2.53 kg, and the volume is relatively small, so it is light to ride and easy to carry. 3. Price and warranty period: At present, the mainstream battery on the market is 48 volts. If replaced, the lead-acid battery is about 450 yuan, and the warranty period is 1 year; the price of lithium batteries is relatively expensive, about 1,000 yuan, but the warranty period is Two years. 4. Driving kilometers: It is also a 48-volt battery. When fully charged, both lead-acid batteries and lithium battery electric vehicles can travel 3,040 kilometers. The speed depends on the size of the motor used. 5. Battery capacity: lead-acid battery capacity is about 20 amps; lithium battery UPS capacity is 810 amps. 6. Environmental protection: Lead-acid UPS batteries are polluted during the processing process, which may cause pollution if they are improperly recycled; UPS lithium batteries are relatively green and environmentally friendly, do not contain any heavy metals and rare metals, are non-toxic, and are non-toxic during processing and use. Pollution, in line with European RoHS regulations, is a green battery. 7. The nominal voltage is different: the nominal voltage of the lead-acid battery cell: 2.0V; the nominal voltage of the lithium battery cell: 3.6V. Advantages of UPS lithium battery: ●Lithium battery pack is smaller and lighter. The volume of a lithium battery is 2/3 of the volume of a lead-acid battery, and its weight is about 1/3 of the weight of a lead-acid battery. Lithium batteries of the same volume have a higher capacity than lead-acid batteries. ●Long life: Lithium iron phosphate battery pack has a longer service life under the same conditions, and the general service life is basically about 4 to 5 years. ●Excellent high temperature performance: The thermal peak of lithium iron phosphate battery can reach 350~500℃. ●Fast charging: high current 2C can be charged and discharged quickly, and the battery can be fully charged within 40 minutes under a dedicated charger at 1.5C. ●Safe and reliable: Lithium iron phosphate has passed strict safety tests and will not explode even in severe collisions. ●Environmental protection: In line with European RoHS regulations, it is a green battery. ●No memory effect: it can be used as soon as it is charged, no need to discharge completely and then charge. ●Good performance: strong power, quick charge and quick release. Advantages of lead-acid batteries: ●The price is cheap, and quite a few manufacturers choose to use lead-acid batteries in order to spend the cost on other structures of electric vehicles; ●The concept of repairable, battery repair can extend the service life has been recognized and accepted by the majority of customers, and If it is damaged within the scope of the warranty, the old can be replaced with a new one; ●High impact resistance, strong impact resistance, will not cause damage to the battery due to usual bumps; Disclaimer: Some pictures and content of articles published on this site are from the Internet , If there is any infringement, please contact to delete the previous article: Do you know whether to choose lithium batteries or lead-acid batteries for electric vehicles?
