AGM Battery Voltage 12V 33Ah VE12-33 (Lifespan 6-9 years)

The Voltage VE12-33 is a high-quality VRLA AGM (Valve-Regulated Lead-Acid, Absorbent Glass Mat) battery designed for reliable backup power and cyclic applications. With a nominal voltage of 12V and a capacity of 33Ah (20-hour rate), it delivers consistent performance for UPS systems, solar installations, alarm systems, emergency lighting, and telecommunications. Its maintenance-free, spill-proof construction ensures safe operation in any orientation.

Advantages

Sealed AGM technology eliminates the need for water refilling and prevents acid leakage. The battery offers a long float life of 6-9 years (Eurobat Commercial standard) and low self-discharge of less than 3% per month at 25°C, making it ideal for standby applications. High discharge capability (330A for 5 seconds) supports demanding loads.

Suitable for

• UPS (Uninterruptible Power Supplies)
• Solar energy storage systems
• Alarm and security systems
• Emergency lighting
• Telecommunications equipment
