EnerRocket ESH 12-400W FR SMF VRLA Battery
The EnerRocket ESH 12-400W FR is a 12V high rate SMF VRLA battery rated at 400W per cell for 15 minutes, engineered for applications that demand strong short-duration power delivery such as UPS systems, telecommunication networks, fire alarm and security installations, and medical equipment. Its thin plate pure lead grid construction and very low internal resistance of 4.4 mΩ deliver high discharge current with fast recharge capability, while the flame-retardant FR-V0 grade ABS container adds an extra layer of installation safety. With a 12-year design life as per EUROBAT standards, non-spillable sealed construction and completely maintenance-free operation, the ESH 12-400W FR is built for long-term reliability in critical backup applications.
