12 Volt 5.1 Ah Sealed Lead Acid Battery
This 12 Volt sealed lead acid battery delivers 5.1 amp hours and 21 watts of power using advanced AGM technology. The recessed polarized terminals ensure a secure connection for compatible devices. It is built for maintenance-free operation in any position and carries a non-spillable classification for safe transport. Expected service life ranges from four to seven years depending on application.
100 Percent OEM Replacement for UPS and Backup Units
This unit serves as a direct OEM replacement for existing sealed lead acid batteries in uninterruptible power supplies and backup devices. The jump is worth it when the original battery no longer holds sufficient charge or shows reduced runtime. Gas recombination technology handles over 90 percent of generated gas during normal use to extend operational life. A three-year warranty covers UPS and backup applications while other devices receive two years.
5.1 Amp Hour Capacity for Standby Power Loads
The 5.1 Ah capacity comfortably handles typical standby loads for home alarm systems emergency lighting and small UPS units. It runs out quickly under sustained high-current draw or deep-cycle demands beyond its rated specification. The sealed construction prevents electrolyte leakage from terminals or case in any orientation. No watering or specific gravity checks are required during the expected floating service life.
