Description

The Starmax High-Temperature GEL Deep Cycle AGM Battery is a high-performance deep cycle GEL AGM battery designed for solar power systems, off-grid energy storage, wind power applications, sweepers, golf carts, and light industrial electric vehicles. Built for extreme temperatures (-15°C to 60°C), it features low self-discharge (2–3% per month at 25°C), a 50% DOD cycle life of over 3,000 cycles, and a float service life of 12–15 years. Supports fast charging and comes with CE, UL, ISO, and IEC certifications. Available in a grey body with black cover, it offers 1–3 years warranty depending on application, providing reliable, long-lasting power for industrial and renewable energy applications.
