　　How to choose button battery cr1620 and how to maintain it?

　　When choosing an button battery cr1620, you should pay attention to issues such as the station, technical performance, reliability and self-protection function; you should usually pay attention to maintaining a suitable ambient temperature, charge and discharge regularly, and replace waste/bad batteries in a timely manner. The following is a detailed introduction. How to choose button battery cr1620 and maintenance method".

　　1. How to choose button battery cr1620

　　1. At the station, in the early stages of operation, one computer plus one printer requires little power and does not require high power accuracy, so the backup type is often used. Nowadays, the number of networked computers and other electrical equipment in each station has increased significantly, and the available power requirements are higher. It is recommended to use online UPS. Online UPS has voltage stabilization, frequency stabilization, zero switching time, and no interference to the load. It is especially suitable for stations far away from urban areas and with large power fluctuations.

　　2. In terms of technical performance,

　　First, we must consider the advancement of technology. For example, it is best to have DSP control technology; support economic mode (ECO mode); power distribution type with high power requirements (such as radar) requires three inputs and three outputs (three-phase five-wire); wide input voltage range, etc.

　　Second, the performance indicators must meet the requirements. Such as higher power factor, stronger load capacity; modular design and high reliability.

　　Third, the output voltage should have good stability and the ability to withstand instantaneous overload.

　　3. In view of the all-weather and uninterrupted working characteristics of weather stations, the selection of UPS should pay more attention to reliability and should be suitable for long-term uninterrupted work.

　　4. For long-lasting UPS, the external battery pack must be sufficient and have digital charging and discharging and self-protection functions.

　　5. If you do not consider configuring a large-capacity battery pack, when configuring a UPS, you need to consider that the UPS is allowed to be used with a generator. At the same time, the power ratio between the UPS and the generator must be determined according to the load conditions. Where it is convenient and timely to start the generator, you can consider appropriately reducing the button battery cr1620 configuration to reduce UPS procurement and update costs. On the contrary, increase the number of batteries configured and extend the battery power supply time.

　　6. If the additional battery pack is limited by the UPS’s local charging circuit, consider adding additional smart charging equipment.

　　7. Determine the working time of the battery. Under normal circumstances, when fully loaded, the battery power supply time = (battery pack operating voltage * battery pack capacity) / (host power * power factor).

　　8. The performance and price of UPS are directly proportional. The more performance and higher the indicators, the higher the price. For example, whether it is a metal shell, whether it has an input/output isolation transformer, whether it has power factor compensation, whether it has SP control, whether it has a large-screen LCD display, etc., each item has added value. When choosing UPS equipment for ordinary stations, it is recommended not to pursue too many performance indicators. It depends on the needs, as long as the performance is usable and the cost-effectiveness is high enough.

　　9. When selecting UPS equipment, consider the size of the space for placing the UPS power system equipment, the safety of use and maintenance, etc.

　　10. The brand, credibility and localization rate of UPS equipment are also factors to consider. At present, the performance and quality of UPS of domestic brands can meet the needs, and the after-sales service is perfect, which is worth considering when purchasing.

　　2. button battery cr1620 maintenance methods

　　1. Maintain a suitable ambient temperature

　　In order to effectively charge the button battery cr1620, the ambient temperature range should be between 5-30 degrees. Generally, the charging efficiency will increase with the increase of temperature. However, when the temperature rises above 45 degrees, the performance of the rechargeable battery materials will degrade at high temperatures. , the battery cycle life will also be greatly shortened.

　　2. Charge and discharge regularly

　　The float voltage and discharge voltage in the UPS power battery have been adjusted to the rated value when leaving the factory, and the discharge current increases with the increase of the load. The load should be reasonably adjusted during use, such as controlling electronics such as microcomputers. The number of devices used. Under normal circumstances, the load should not exceed 60% of the UPS rated load. Within this range, the discharge current of the button battery cr1620 will not be over-discharged.

　　3. Replace waste/bad batteries promptly

　　In the continuous operation and use of UPS batteries, due to differences in performance and quality, it is inevitable that the performance of individual batteries will decline and the storage capacity will not meet the requirements and be damaged. When certain batteries/batteries in the battery pack are damaged, maintenance personnel should inspect and test each battery to eliminate damaged batteries. When replacing a new UPS power battery, you should strive to purchase batteries of the same manufacturer and model. It is prohibited to mix acid-proof batteries, sealed batteries, and batteries of different specifications.
