Lead-acid batteries mostly operate in float-charging mode within backup power systems. When mains power is normal, UPS or power cabinets supply constant low voltage to compensate for self-discharge loss and keep batteries fully charged for standby. Float voltage must be precisely controlled: excessive voltage accelerates water loss and aging, while insufficient voltage causes undercharging. VRLA lead-acid batteries feature low self-discharge rate, ideal for long-term float standby. Once grid power fails, batteries instantly release electricity to support loads until power recovery. Mastering float maintenance rules and regular status inspection can effectively extend service life and ensure emergency power systems ready for use anytime.
