Battery bulging, premature aging and frequent replacement usually stem from defective UPS charging boards that trigger continuous abnormal overcharging. Poor charging board design is a common hidden flaw on low-cost UPS units and brings huge extra maintenance costs for users.

✅ Faulty voltage sampling circuit

Damaged sampling components fail to read actual battery voltage, the charger keeps feeding power nonstop and overcharges batteries severely.

✅ Broken PWM master control chip

Invalid chip logic loses automatic charge cutoff after full battery, resulting in long-duration overcharge.

✅ Inferior PCB layout & thin copper

Cheap boards use thin copper traces, high-load heating drifts component parameters and ruins charging closed-loop control.

✅ Invalid temperature compensation circuit

No ambient temperature adjustment for charging voltage; high room temperature easily causes thermal runaway overcharge.

Why Daopulse UPS effectively avoids overcharge risks?

All Daopulse finished UPS equip self-developed high-grade charging boards as core standard configuration:

1. Main power circuit PCB ≥2oz thick copper with standardized routing, restrict heating drift effectively;

2. Independent precise voltage sampling circuit + dual temperature compensation design;

3. Multi-protection hardware: overcharge cutoff, overheat lock, reverse connection prevention built-in.

Thanks to premium built-in charging boards, Daopulse whole machine UPS greatly reduces battery damage rate, extends overall battery service life and improves long-term UPS running stability for industrial, data center and commercial projects.
