Sealed AGM Battery Voltage VEL12-7.0 12V 7Ah Long Life (15 years)

The Sealed AGM Battery Voltage VEL12-7.0 12V 7Ah Long Life is a valve-regulated, sealed lead‑acid battery designed for maintenance-free operation and extended service life. Built with absorbed glass mat (AGM) technology, this 12V 7Ah unit delivers stable voltage and reliable performance for applications that require dependable standby power and periodic deep cycling. The battery is suitable for installations where low self-discharge, leak-free operation and long storage life are important.

Advantages

This sealed AGM battery provides maintenance-free use due to its valve-regulated design and absorbed glass mat separator, which prevents electrolyte leakage and reduces water loss. The construction supports good deep-cycle capacity and consistent output under typical discharge and recharge cycles. Rated for a long service life, the battery offers low self-discharge for extended shelf life and stable performance in a range of ambient conditions. Its compact, rugged casing simplifies mounting in confined equipment compartments.

How to use

Install the battery in a well-ventilated, dry location away from heat sources and direct sunlight. Connect using appropriate polarity-aware connectors and ensure terminals are clean and secure. For standby applications, follow the recommended float charge voltage range provided by the system manufacturer; for cyclic use, apply the correct charge algorithm for sealed AGM batteries. Observe safety precautions for lead‑acid batteries: avoid short circuits, do not disassemble the sealed casing, and handle with protective equipment if servicing is required. Dispose of the battery in accordance with local regulations for lead‑acid battery recycling.

Usage recommendations

To maximise service life, keep the battery on a proper float charge for standby applications and avoid prolonged deep discharges. Store the battery at a partial state of charge in a cool, dry place and perform periodic recharge during long storage intervals. Use a charger or charger setting compatible with sealed AGM batteries to ensure correct charge voltage and to prevent overcharging.
