When to Replace Your UPS Battery

• UPS shows frequent alarms or fault lights.
• Backup runtime is significantly reduced.
• Battery is near or past its rated life (typically 3–5 years for lead-acid UPS batteries).
• Visible damage, swelling, leaking, or corrosion.

Safety Precautions

Always follow basic safety: wear gloves and eye protection, work in a well-ventilated area, and avoid sparks or open flames. If in doubt, contact a qualified technician or TIANDONG support.

Tools and Parts Needed

• Compatible replacement UPS battery (check voltage, capacity, terminal type).
• Insulated screwdriver set, wrench, and terminal cleaner.
• Multimeter for voltage checks.
• Protective gloves and safety glasses.
• Battery recycling container or local disposal guidance.

Step-by-Step Replacement Process

1. Prepare: Verify replacement battery model and condition. Confirm UPS is on utility power and fully charged if possible.
2. Shutdown or Bypass: If your UPS supports hot-swap, follow the manufacturer’s bypass procedure. Otherwise, safely shut down connected equipment and the UPS according to its manual.
3. Disconnect Power: Unplug the UPS from mains and switch off output breakers to remove any load.
4. Open Battery Compartment: Locate the battery pack. Note wire positions and take a photo to ensure correct reconnection.
5. Remove Old Battery: Disconnect terminals (negative first), remove hold-downs, and carefully extract the battery. Handle leaking batteries with caution and place them in a safe container for transport.
6. Install New Battery: Place the new UPS battery into the compartment, secure with hold-downs, and reconnect terminals (positive first). Ensure tight, clean connections without over-tightening.
7. Initial Charge and Test: Power the UPS and allow the battery to charge fully. Run a self-test or controlled power failover to confirm backup runtime and proper operation.
8. Dispose Properly: Recycle the old battery per local hazardous waste rules. TIANDONG supports responsible disposal and can advise on recycling options.
