Battery2Batteries.com supplies replacement batteries for Dual-Lite emergency lights, exit signs, combination fixtures and commercial life-safety lighting systems. Find the correct replacement by Dual-Lite battery number, fixture model, voltage, capacity or battery configuration.
Dual-Lite emergency-lighting systems use different rechargeable batteries depending on the fixture family and model. Depending on the application, Dual-Lite products may use sealed lead-acid or nickel-cadmium battery systems. Match the original Dual-Lite battery number or fixture documentation whenever possible.
Start with the exact Dual-Lite battery number printed on the original battery pack. Many Dual-Lite batteries are identified by both a six- or seven-digit part number and a shorter 12-series number, such as 0120803 / 12-803. Match the complete battery or fixture information before ordering.
Dual-Lite identifies 0120803, also referenced as 12-803, as a 12V sealed lead-acid emergency-lighting battery. Dual-Lite documentation specifies it as a 7.2Ah approved battery for supported emergency-lighting applications. :contentReference[oaicite:3]{index=3}
