Description
The Weida HX12-55 is a 12-volt sealed lead-acid (VRLA/AGM) battery with 55 Ah nominal capacity, engineered to deliver stable, maintenance-free power for a wide range of applications. It’s designed for use in UPS systems, solar/inverter backup, telecom/security equipment, emergency lighting, mobility devices (e.g. wheelchairs, scooters), and other 12 V DC systems — providing dependable energy storage with deep-cycle and standby capabilities. The sealed, non-spillable construction makes it safe for indoor or enclosed installations.
✅ Key Features
-
Sealed & Maintenance-Free Design (VRLA/AGM): No need to top up water or monitor electrolyte — the battery is sealed and ready to use.
-
High Capacity — 55 Ah: Provides a generous energy reserve for longer backup, solar storage, or sustained loads.
-
Low Self-Discharge: Retains charge well during storage or standby periods, making it ideal for backup systems or rarely-used equipment.
-
Good Deep-Discharge Recovery: Even after prolonged or deep discharges, the battery recovers reliably during recharge — suitable for cyclic use (solar, mobility devices, repeated discharge/charge cycles).
-
Strong Discharge & High Current Capability: Capable of delivering high short-term current (for surge loads, inverters, or motors) — enabling flexibility in equipment powered.
-
Wide Operating Temperature Range: Designed to operate under varied environmental conditions — discharge, charge, and storage temperature ranges enable use in different climates.
-
Durable & Reliable Construction: Built to resist vibration, shocks, over-charge / over-discharge, and other typical stresses — increasing longevity and consistency.
-
Versatile Applications: From UPS/backup power and solar energy storage to mobility devices, telecom equipment, and general 12 V DC systems — useful across many use-cases.
