The terminal corrosion of the battery is divided into chemical corrosion. It is simply that it is acid corrosion; there is electrochemical corrosion, due to the difference in potential difference due to the differential column contact materials. The battery joint is corroded, rust, and dirt, will increase the contact resistance, resulting in difficulties in this state, and the power generation will increase the power consumption in this state! The root cause of battery terminal corrosion: 1, terminal leakage; 2.
Terminal contact to acidic rain; 3, battery often use in wet environment; 4, there is a contact resistance between terminal line cards. Battery terminal corrosion effective treatment: Connection line card is applied to the best butter. Explanation: Oil and butter do not affect the conductive capacity, the new battery is installed, it is recommended to drop two droplets on the terminal, it can prevent corrosion.
Below is important, the charging current is too large, the single battery charging voltage exceeds 2.4V, there is a short circuit or the lead-acid battery short circuit caused by short circuit or local discharge, temperature rise, and the valve failure phenomenon is analyzed. Approach.
1, reduce the charging current, reduce the charging voltage, check if the safety valve body is blocked. Regular charging discharge. The lead-acid battery floating voltage and discharge voltage in the UPS power system, many of which have been commissioned to the rated value during the factory, and the size of the discharge current increases with the increase of the load, and the load should be reasonably adjusted.
For example, the number of applications of electronic devices such as computers. Under normal circumstances, the load should not exceed 60% of the UPS rated load. Within this range, the battery does not excessive discharge.
The lead-acid battery storage will lose part capacity due to self-discharge, and therefore, before the lead-acid battery is put into use, the residual capacity of the battery should be determined according to the battery's open circuit, and then supplement the battery to supplement the battery. Battery for standby shelves, supplementary charging should be performed every 3 months. You can determine the battery's good or bad by measuring the puffy battery open circuit.
2, as an example of 12V battery, if the open circuit voltage is higher than 12.5V, it means that the battery energy is more than 80%, if the open circuit voltage is below 12.5V, it should be replenished immediately.
If the open circuit voltage is less than 12V, it means that the battery storage electrical can be less than 20%, the battery is unable. When the battery is short-circuited, the short circuit current can reach hundreds of amps. The shorter contact is related, the larger the short circuit current, so all connecting parts will have a lot of heat, and the heat of the weak link is greater, the connection is blown, short-circuit phenomenon.
