CR2032 button cell batteries

　　What are the characteristics of CR2032 button cell batteries and how to maintain them?

　　CR2032 button cell batteries have excellent performance, very small self-discharge, long life, good economy, and excellent recovery ability after deep discharge. They should maintain a suitable ambient temperature, charge and discharge regularly, and replace waste/bad batteries in a timely manner. Here is a detailed introduction "Characteristics and maintenance methods of CR2032 button cell batteries".

　　1. Characteristics of CR2032 button cell batteries

　　1. Simple: The gas appearing inside the UPS battery during charging is basically absorbed and reduced to electrolyte, and there is basically no electrolyte.

　　2. The electrolyte with high liquid holding capacity is absorbed in the special separator and remains in a stagnant state, so it can be used even if it falls down.

　　3. Superior performance: excessive gas can be released due to extreme overcharging operation errors to prevent battery rupture.

　　4. Minimal self-discharge: special lead-calcium alloy is used to produce grids to control self-discharge to a minimum.

　　5. Long life and good economy: The UPS battery grid is made of special lead-calcium alloy with good corrosion resistance. At the same time, special partitions are used to protect the electrolyte, and at the same time, the positive plate is pressed to activate and prevent falling, so it is a kind of Long life, economical battery.

　　6. Small internal resistance: Due to the small internal resistance, the large current discharge characteristics are good.

　　7. Excellent recovery ability after deep discharge: In case of long-term discharge, as long as it is fully charged, the capacity will basically not appear and it can be restored quickly.

　　2. UPS battery maintenance methods

　　1. Maintain a suitable ambient temperature

　　In order to effectively charge the UPS battery, 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. Regular charging and discharging

　　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 UPS battery will not be over-discharged.

　　3. Replace waste/bad batteries promptly

　　In the continuous operation and use of CR2032 button cell batteries, due to differences in performance and quality, it is inevitable that the performance of individual batteries will decline, the storage capacity will not meet the requirements, and damage will be inevitable. 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.
