Power instability in Dhaka kills hardware. A working UPS is the difference between a clean shutdown and a corrupted drive. BAYAS UPS Repair Service keeps your offline, line-interactive and online UPS units alive across home and office sites in Dhaka.
We service every major brand in the Bangladesh market — APC by Schneider, Mercury, Power Guard, Power Tree, Long, Eaton, CyberPower and Vertiv. From a 650 VA desktop UPS to a 6 kVA online tower, the same disciplined diagnostic applies: load test, battery health check, inverter waveform check, and PCB inspection.
Sealed lead-acid batteries account for the majority of UPS faults. We use original capacity-rated replacement batteries from authorized Dhaka suppliers, never recycled cells masquerading as new.

UPS Repair Service — FAQ
How often should I replace UPS batteries?
Sealed lead-acid batteries in Dhaka heat last 18 to 30 months on average. We recommend an annual capacity test to catch decay early.
Can BAYAS service online UPS units?
Yes. We service 1 kVA to 6 kVA online UPS units on-site and larger units at the workshop with pickup and delivery.
Do you use genuine batteries?
Yes — we source original capacity-rated batteries from authorized Dhaka distributors with retail invoice in your name.
Why does my UPS beep constantly?
Continuous beeping usually means the battery is weak, the load is too high, or the unit is overheating. We diagnose all three in one visit.
Do you offer annual maintenance?
Yes. Annual maintenance contracts include preventive cleaning, capacity test, fan service and priority response.
