There are specialized battery testing instruments available to assess the condition of a battery, but these tools are not commonly found among regular users. Most people only have a multimeter at their disposal. Based on practical maintenance experience, here are some methods to evaluate the quality of a battery for reference.
1. **Visual Inspection**: Check the battery’s appearance for any signs of deformation, bulging, leakage, cracks, or burn marks. Also, ensure there is no oxidation at the terminal connections. Any of these issues may indicate a faulty or aging battery.
2. **Load Testing**: If the battery looks fine, place it under a load while the UPS is operating in battery mode. If the discharge time is significantly shorter than usual and even after 8 hours of charging, the backup time doesn’t return to normal, this could be a sign of battery aging.
3. **Multimeter Testing**:
- **Discharge Mode Measurement**: Measure the voltage of each individual battery in the pack. If one or more batteries show a voltage that is much higher or lower than the nominal value (e.g., 12V per cell), the battery may be deteriorating.
- **Charging Mode Measurement**: While the battery is being charged, check the voltage of each cell. If one or more cells show a significantly different voltage compared to others, it might be an indication of aging.
- **Total Voltage Check**: Measure the total voltage of the entire battery pack. If it's much lower than the expected nominal value (for example, 36V for a C1K system) and even after 8 hours of charging it cannot return to normal, or if it does return but the discharge time is still inadequate, the battery is likely aged.
- **Startup Test**: When the UPS is not connected to the mains, first measure the total battery voltage using a multimeter. For a C1K system, the voltage should be between 36V and 40V, which is normal. Press the power button. If the voltage drops below 30V or even to single digits, and the UPS shuts down immediately, with the voltage returning to its original level after shutdown, this is a strong indicator of a failing battery.
