The MK Battery ES7-12 is a sealed, maintenance-free 12V lead-acid battery delivering 7.2Ah designed for reliable standby and cyclic use.

The ES7-12 is part of MK Battery’s VRLA (Valve Regulated Lead Acid) range, engineered to provide dependable power in a variety of devices where leak-free, low-maintenance energy is essential. Built to ISO 9001 and ISO 14001 standards and UL certified, this battery is suitable for both everyday backup tasks and repeated discharge/charge cycles commonly found in mobility equipment, security systems, and emergency lighting.

What performance can I expect from the ES7-12 in everyday use?

The ES7-12 is rated at 7.2 amp-hours at the 20-hour rate, giving predictable run times in low-to-moderate power draw applications. Its VRLA design controls internal gas recombination so the battery remains sealed and maintenance-free, reducing the need for regular inspections or water additions. Expect consistent voltage delivery for standby systems and good cycle life when used as recommended.

• Capacity: 7.2Ah at 20-hour rate for steady runtimes
• Voltage: 12 volts suitable for many small systems
• Sealed VRLA construction prevents leakage and spills
• UL safety certification and ISO-managed manufacturing

How easy is installation and what fittings does it use?

Installation is straightforward: the ES7-12 comes with F1 (Faston Tab 187) terminals that fit common quick-disconnect connectors used in consumer and industrial equipment. Its compact, rectangular case is designed for tight compartments, making it easy to replace older batteries or add to modular systems. No special tools are required beyond basic terminal connectors and a secure mounting surface.

• Terminals: F1 faston tab 187 for quick connections
• Compact form factor for space-limited installations
• Sealed case eliminates acid handling during replacement

Which applications are best suited for this MK Battery model?
