A battery can look healthy and show normal float voltage while having lost much of its capacity. Health testing reveals that hidden risk before a real outage exposes it.
What health testing measures
- Voltage: identifies blocks that are out of balance
- Internal resistance or conductance: tracks ageing and weak cells
- Capacity or discharge testing: confirms actual backup time
- Temperature and visual inspection: detects swelling, leakage and loose connections
Benefits
- Find weak blocks before they cause a string failure
- Plan replacements and budgets in advance
- Support warranty claims with documented test data
- Maintain uptime for critical loads
How often to test
Critical UPS, telecom and industrial banks benefit from periodic testing, typically quarterly or half-yearly, with trend analysis over time. Frequency should reflect load criticality, battery age and site conditions.
Battery Ghar offers health audits with a report and recommendations for your battery banks.
