Lightwave 12V/12Ah UPS Battery – High Performance SMF Battery (LW 12AH)

The Lightwave LW 12AH is a high-performance 12V 12Ah sealed maintenance-free (SMF) battery designed to deliver reliable backup power for UPS systems, emergency lighting, security systems, and other standby applications. Built with valve-regulated lead-acid (VRLA) technology, it is maintenance-free, leak-proof, and engineered for long-lasting, stable performance. Compact yet powerful, the LW 12AH ensures consistent energy output under varying temperatures and load conditions, making it ideal for both cyclic and standby use.

Product Features

Maintenance-Free VRLA Design

Sealed VRLA construction eliminates the need for water or electrolyte top-ups, ensuring convenient, hassle-free operation.

Compact and Durable

Constructed with high-impact ABS plastic and lead-calcium grids, the battery measures approximately 151 × 99 × 101 mm (with terminals) and weighs 3.2 kg, combining robustness with space efficiency.

High Performance

Delivers stable energy with low internal resistance (~17 mΩ fully charged) for efficient power transfer and reliable backup.

Leak-Proof and Safe

Spill-proof design allows safe operation in multiple orientations without the risk of leakage.

Wide Operating Range

Maintains optimal capacity across temperature extremes: 102% at 40°C, 100% at 25°C, and 85% at 0°C. Operates reliably from –15°C to +50°C (charge: –15°C to 40°C; discharge: –20°C to 50°C).

Versatile Applications

Ideal for UPS systems, security devices, emergency lighting, telecom/networking equipment, small solar energy storage, and electric scooters.

Optimized Charging

Supports cycle/deep discharge use with 14.4–15.0 V charging, and standby/float mode at 13.5–13.8 V, with a typical recharge time of 6–8 hours to 90% capacity.
