Battery life is almost the same. Regarding the personal use of lithium batteries, lithium batteries are light in weight and have a long charge and discharge cycle life (600 times of ternary charge and discharge, 2,000 times of iron-lithium ). , and 400 times that of lead). The lithium battery has 4812 specifications. It weighs 9 kilograms, and the 4812 lead-acid battery weighs 27 kilograms. The car is light, a little faster and the range is about the same (. the speed is faster and the energy consumption is greater). The lithium battery is easy to disassemble and take away for charging (note that it is prohibited to bring it into high-rise residential buildings. Lithium batteries are charged upstairs).
When lithium batteries are used, their lifespan slowly decreases as they age. A normal battery can maintain 90% ofthe life of the new battery after one year, but the performance of the internal cells of many lithium batteries is unbalanced. (the difference between the capacity and the internal resistance (large), resulting in a considerable reduction in the life of the lithium battery after being charged and discharged 400 times after two years of use. 35 to 40 kilometers with a new battery, it can only run ten kilometers after two years, it even loses power when accelerating, making it impossible to drive The battery needs to be repaired and replaced The battery life may be. extended up to 30 kilometers, but the overall battery life is aging and individual lithium battery failures will occur soon and the battery life will decrease again
After. have used a new lead-acid battery, the battery life decreases quickly after a period of time.year it can only travel more than 20 kilometers, and in two years it will reach almost a dozen kilometers (my last). the car had a 4820 battery, and the new one has a range of 65 kilometers, the range after seven years can still be 25),

Energy
Performance
1. Lead-acid batteries (lead-acid gel batteries) are cheap and have high stable performance, most electric vehicles on the market use this type of battery.
2. Lithium-ion batteries (often called lithium batteries) are more expensive, but they have high specific energy, power shigh specificity, low self-discharge, no memory effect, good cycle characteristics and wide operating temperature range, no environmental pollution and other advantages.
3. Crystal gel batteries have high cost and stable performance. There are very few electric vehicles using this type of battery on the market. Only a few companies equip them with this high-performance battery. highest safety factor. The advantage of much longer service life than the first two types of batteries and the advantage of self-healing function also constitutes the leading position in the industry. The advantage is that lead acid batteries do not have them, and the disadvantages. Delamination of lead-acid batteries can be avoided.
Types
Primary batteries: Disposable batteries that are discarded after use and cannot be reused, such as carbon-zinc batteries, pialkaline, mercury and lithium batteries.
Secondary batteries: rechargeable and reusable, such as: nickel-cadmium rechargeable batteries, nickel-metal hydride rechargeable batteries, lithium rechargeable batteries, lead-acid batteries, solar cells, crystalline gel and lithium batteries iron phosphate. batteries.
Divided according to use
Industrial use
Example: used in factories for integrated products, which have a specific appearance or are composed of several particles , such as: electriciansTools, communication batteries, etc.
Use by the general public
Example: For general public use, replacement batteries can be purchased from the market. The most commonly used cylindrical protruding head batteries.
