The types of batteries are:
1. Lead-acid batteries
Commonly used lead-acid batteries are mainly divided into three categories: ordinary batteries and dry charge batteries. and maintenance-free batteries, the plates of ordinary batteries are composed of lead and lead oxides, and the electrolyte is an aqueous solution of sulfuric acid. The main characteristic of dry charge batteries is that the negative plate has high energy storage capacity. Maintenance-free batteries have structural defects. Advantages: Electrolyte consumption is very low and there is virtually no need to replenish the distilled water during the shelf life.
Lead-acid batteries are widely used in electric power, energy storage, electric vehicles and other fields. Particularly, its advantages such as mature technology and low cost make itdifficult to replace it with other battery products in the short term.
2. UPS Battery
The UPS is called uninterruptible power supply because in the event of a power outage, it can quickly switch to the "inverter" state, preventing the use of the battery. . The computer loses important files due to a sudden power outage before it has time to store them.
3. Lithium iron phosphate battery
Lithium iron phosphate battery is the safest specific energy battery in the lithium-ion battery family. The discharge voltage is very stable, generally 3.2V. When discharged to The voltage changes rapidly when 10% remaining capacity is reached and the cut-off voltage is typically 2.5V.
4. Great battery
Great battery. It is also an engine starting power supply. This is a device that can provide starting power to the wordinternal combustion engine through rapid energy storage when the traditional battery equipped with the internal combustion engine fails and cannot start.
The battery is a widely used chemical “energy source” around the world. It has the advantages of stable voltage, safety and reliability, low price, wide application range, abundant raw materials and high recycling rate. the most produced and used battery among batteries.
Detailed information
Some issues that need to be paid attention to when using and maintaining batteries:
1. the battery is not used for a long time, it will discharge slowly until it is discarded. Therefore, the car must be started at regular intervals to charge the battery.
2. When the ammeter pointer indicates that the headingBattery capacity is insufficient, charge it in time. Battery capacity can be reflected on the dashboard.
3. The density of the electrolyte should be adjusted accordingly according to the standards of different regions and seasons.
4. If electrolyte loss occurs, distilled water or a special rehydration solution should be added. Do not use plain water instead. Since pure water contains various trace elements, it will have adverse effects on batteries.
5. When starting the car, continued use of the starter motor may damage the battery due to over-discharge.
6. When driving daily, you should always check whether the small hole on the battery cover is ventilated. If the small hole in the battery cover is blocked, the hydrogen and oxygen generated cannot be discharged. When the electrolyte expands, it will burst the battery shell and affectra its lifespan.
7. Check the power supply. Check for signs of oxidation on the positive and negative floors of the pool. You can frequently pour hot water over the battery wire connections, clean them with a copper wire brush, and apply butter.
8. Check for aging or short circuits in all parts of the circuit. Prevents the battery from prematurely discharging due to over-discharge.

In what areas are batteries useful UPS uninterruptible power supplies? How many volts? Is it a combination?
It will be launched on February 8, 2023.
The Jispace U2600 uninterruptible power supply UPS computer will be officially launched on February 8, 2023. This product has one thenMaximum output power of 120W and 60W uninterruptible power supply. With lithium battery and built-in intelligent processor, it can automatically warn to shut down when power failure and automatically warn to turn on when a call comes in. For equipment requiring protection, such as NAS equipment, this intelligent uninterruptible power supply is valuable protective equipment.
Are lithium batteries toxic?
There are several types of internal batteries in regular UPSs. Most 300VA UPSs are 6V, and a few are 12V. Unnamed 500VA UPSs use 6V, and most good quality ones are 12V. 1KVA UPSs have 12V and 24V Yes, those above 3KVA are basically external batteries. A battery bank is made up of N batteries connected in series. The biggest UPS I've seen uses 16 batteries in secondsseries with a voltage of 192V.
UPS (Uninterruptible Power System), i.e. uninterruptible power supply, is a constant voltage and constant frequency uninterrupted power supply that contains an energy storage device and uses a inverter as the main component. It is mainly used to provide uninterrupted power supply to a single computer, computer network system or other power electronic equipment. When the mains input is normal, the inverter stabilizes the mains voltage and supplies it to the load. At this time, the inverter is an AC mains voltage stabilizer and also charges the internal battery when the mains power is interrupted (accidental power supply). fault) When the inverter is working, the inverter will immediately continue to supply 220V AC power to the load via the inverter conversion method from the inverter battery powerdull, so that the load can maintain normal operation and protect the software and hardware of the load. Shame. UPS equipment typically provides overvoltage and undervoltage protection.
Lithium batteries do not contain or produce lead, mercury, cadmium and other toxic and harmful heavy metal elements and substances, whether used or discarded, and are relatively less polluting. And its electrolyte is organic solvent and lithium salt, most of which are non-toxic or low toxicity.
Compared to traditional batteries such as lead-acid, nickel-chromium and nickel-metal hydride batteries, lithium batteries contain very few toxic elements.
However, it should be noted that although lithium batteries themselves are non-toxic, the decomposition or hydrolysis products are hydrofluoric acid and other co-compounds.containing fluorine, which are corrosive and toxic. So treat yourselfIt must be treated according to reasonable procedures.
Detailed information:
Lithium batteries are widely used in hydropower, thermal energy and wind energy. electricity and solar energy Energy storage power supply systems such as power stations, uninterruptible power supplies for posts and telecommunications, as well as power tools, electric bicycles, electric motorcycles, electric vehicles, military equipment, aerospace and other fields.
Lithium-ion batteries have been widely used in portable devices such as laptops, cameras and mobile communications due to their unique performance advantages. The developed large-capacity lithium-ion battery was tested in electric vehiclesics and is expected to become one of the main sources of energy for electric vehicles in the 21st century and will be used in satellites, aerospace and energy storage.
With the shortage of energy and the pressure of environmental protection in the world. Lithium batteries are widely used in the electric vehicle industry, especially the emergence of lithium iron phosphate batteries, which has promoted the development and application of lithium battery industry.
