MK Battery 12V 7Ah Sealed Lead-Acid Backup Battery ES7-12SA — Maintenance-Free VRLA, Faston F1

The MK Battery ES7-12SA is a sealed, maintenance-free 12V lead-acid battery delivering 7Ah of reliable standby power for security, alarm, and other backup systems.

Designed as part of MK Battery’s VRLA (valve-regulated lead-acid) lineup, the ES7-12SA offers a no-maintenance energy source that resists leaks and delivers consistent voltage for standby and light cyclic duties. Built to meet industry safety and quality standards, this compact battery fits many alarm panels, emergency lights, and small standby power devices where dependable, sealed power is required.

How does the ES7-12SA perform in standby applications?

The ES7-12SA is optimized for standby use, supplying stable current when primary power fails and then remaining ready for repeated cycles. Its valve-regulated design minimizes water loss and prevents leakage, which makes installation safe in upright and enclosed systems.

• Nominal voltage: 12 volts for common backup systems
• Rated capacity: 7 Ah at the 20-hour rate for predictable run times
• Sealed VRLA construction for spill-free operation
• UL-tested and manufactured under ISO 9001 and ISO 14001 processes

Can I use the ES7-12SA in cyclic (frequent discharge) situations?

While the ES7-12SA can support occasional discharges, MK recommends the ES7-12 model specifically for heavier cyclic use. Using this SRLA for frequent deep cycling may reduce its effective service life compared with batteries designed for that purpose.

• Best suited for standby/standby-alarm roles rather than heavy daily cycling
• For repeated deep discharges, choose MK’s cyclic-design equivalents
• Faston F1 terminals enable quick connection and replacement

What are the key specs and physical details I should know?

The ES7-12SA packs its electrical performance into a compact, service-free housing that’s easy to fit into common enclosures. Terminals use the F1 (187) faston tab for simple wiring, and the battery’s sealed body removes the need for periodic watering or maintenance.

• Capacity: 7 AH (20-hour rate) — consistent runtime for small systems
• Voltage: 12 V — compatible with most alarm panels and standby devices
• Terminals: F1 (Faston tab 187) for standard quick-connect hookups
• Sealed, maintenance-free VRLA design for safe indoor use

Who is this for? The MK Battery ES7-12SA is ideal for technicians, facility managers, and homeowners who need a compact, sealed backup battery for security systems, emergency lighting, UPS standby, and similar low-to-moderate draw applications. If you require a maintenance-free, leak-proof power source with recognized manufacturing and safety certifications, the ES7-12SA is a dependable choice; for regular deep-cycle demands, consider MK’s cycle-specific models instead.
