RS PRO Sealed Lead Acid Battery 18 Ah, AGM, T12 Terminal, 12V, 5.4 kg, 150-1557

The RS PRO 150-1557 Sealed Lead Acid Battery is engineered for reliable and robust standby and backup power in demanding environments. Featuring an 18 Ah capacity and 12V nominal voltage, this battery suits uninterruptible power supplies, emergency lighting, and a wide range of industrial and security systems. Its advanced AGM (Absorbent Glass Mat) construction captures electrolytes in glass fiber mats, eliminating spillage risk and ensuring maintenance-free operation throughout its lifecycle.

The T12 terminal configuration offers easy, secure connections, while the battery's rugged, flame-resistant housing provides enhanced safety, even in challenging environments. With a gross weight of 5.4 kg and compact dimensions, it is suitable for equipment where space and reliability are both crucial. The RS PRO maintenance-free design means that no water topping is needed, and the valve-regulated system prevents gas escape unless severely overcharged.

Operating efficiently within a broad temperature range from -20°C to 50°C, this battery maintains performance in cold and hot climates. Lead-calcium alloy grids, free of antimony, protect against corrosion and enhance discharge recovery attributes. The low-gassing design supports vertical or horizontal installation, making the battery suitable for a variety of orientations and mounting conditions.

Typical applications include emergency lighting, auto control systems, railway and aircraft signaling, security alarms, electronic equipment, DC and communication power supplies. The high discharge capability and long shelf life (Eurobat classification: 3 to 5 years) provide reliable service in critical power support roles. Deep discharge protection ensures a longer lifespan and robust cycling performance. Flame resistance is certified, and valve operation delivers non-spillable, safe usage even in sensitive industrial settings.

The battery casing is engineered to resist impact and vibration, meeting the operational needs of industrial, commercial, and transport sectors. Trusted worldwide, RS PRO batteries are ideal for systems that require premium backup and peak discharge characteristics with minimal maintenance requirements.
