Professional Guide to UPS Industrial Battery Maintenance | MHB Battery

Uninterruptible Power Supply (UPS) systems are essential for ensuring continuous power in critical applications—from data centers and hospitals to factories and telecom systems. At the core of these systems are industrial batteries, typically Vrla (Valve Regulated Lead Acid) or AGM (Absorbent Glass Mat) types. Proper maintenance of these batteries is crucial to maximize lifespan and prevent costly downtime.

As a trusted UPS battery manufacturer, MHB Battery shares expert insights to help operators and engineers ensure optimal battery performance and reliability.

?? 1. Why UPS Battery Maintenance Matters

UPS batteries are often the weakest link in backup power systems. Even high-quality batteries can fail prematurely if not properly maintained. Common issues include:

• Capacity loss due to sulfation.

• Terminal corrosion.

• Overcharging or undercharging.

• Environmental temperature fluctuations.

Regular maintenance prevents unexpected failures, extends battery life, and reduces operational costs.

?? 2. Routine Maintenance Checklist

To maintain UPS batteries effectively, follow these key practices:

? Visual Inspection (Monthly or Quarterly)

• Check for swelling, cracks, or leakage.

• Inspect terminals for corrosion or discoloration.

• Ensure tight and clean electrical connections.

? Voltage & Internal Resistance Testing (Quarterly)

• Measure individual battery voltage and compare it to the nominal value (typically 12V).

• Use a battery tester to check internal resistance (IR); increasing IR can signal deterioration.

? Float Voltage Check (Monthly)

• Verify that charging voltage remains within manufacturer-recommended range (e.g., 13.5–13.8V for AGM batteries).

• Avoid overcharging, which accelerates plate corrosion and water loss.

? Ambient Temperature Control

• Maintain room temperature at 20–25°C (68–77°F). Every 10°C increase cuts battery life by nearly 50%.

? Cleaning & Record Keeping

• Clean battery surfaces to avoid dust buildup.

• Keep detailed logs of inspection, voltage readings, and replacement dates.

?? 3. Signs of Battery Degradation

Replace batteries if you notice:

• Decrease in backup time

• Uneven voltages among units

• Alarming temperature increase during operation

• Audible UPS alarms or error codes related to battery
