Plate can be reversed sulphation | 1. Reduced battery capacity. 2. Electrolyte density lower than normal. 3. Start charging and the battery when the charging is completed the Terminal voltage is too high. 4.Charging early bubble or charge so that they have a bubble. 5.When charging,the electrolyte temperature rises too quickly. | 1.Insufficient charging at the beginning. 2. Has been discharged or placed half a discharge status for too long. 3. Insufficient long-term charge. 4. Often excessive discharge. 5. Electrolyte density exceeds the specified value. 6. Electrolyte fluid is too low, cause plates were exposed on liquid surface. 7. do not be balanced charged in time. 8. The discharge current is too large or too small. 9. The electrolyte not pure. 10. Internal short circuit of local effects or leakage. | 1. the Light to adopt a balanced charge approach. 2. serious to use of "water therapy". 3. can't over discharge 4. The electrolyte density can't exceed the specified value. 5. The electrolyte liquid surface height and impurity content should be within the prescribed scope. |
short circuit Inside the battery | 1. When charging the battery, the terminal voltage is very low, even closer to zero. 2. End of charging ,the bubbles fewer or no bubbles. 3. When charging, the electrolyte temperature rise faster and the density rise slowly not even rising. 4. open circuit voltage of Battery is low,Discharge prematurely to cause the voltage terminated 5. Self-discharge serious. | 1. Plate bending, swelling or loss of active substances, leading to partition damage, causing a short circuit 2. Sediment too much, resulting in short-circuit. 3. the conductive material Fall into the battery,resulting in short-circuit. | 1.Replacement clapboard. 2. To remove sediment and conductive material. 3. Replace plate. |
| 1. Reduced battery capacity. 2. Electrolyte turbidity. 3. Too much sediment. | 1. Electrolyte does not meet the quality standards. 2. Charging and discharging too frequently or over charge, over discharge. 3. When charging, the electrolyte temperature is too high. 4. When discharging,the external circuit happen short circuit. | The light to remove sediment,The serious to Scrap |
