## Long description

The Sealed AGM VRLA rechargeable battery COSI 12V 7Ah with T1 (4.75 mm) terminals is a maintenance-free lead-acid battery designed for compact backup power. Its valve-regulated sealed construction uses absorbed glass mat (AGM) technology to immobilize the electrolyte, prevent leakage and allow installation in different orientations. The battery delivers nominal 12 V output with 7 Ah capacity for short-term standby, portable or cyclic use in small systems and devices.
Advantages
This COSI sealed AGM battery offers a stable 12 V output, low self-discharge and a sealed, non-spill design that removes the need for routine watering or electrolyte checks. The VRLA design reduces gas emissions under normal operation and the AGM plates provide improved vibration resistance compared with flooded lead-acid cells. T1 (4.75 mm) terminals simplify wiring and make the battery compatible with common clamps and connectors used in UPS, alarm and lighting equipment.
Suitable for
Uninterruptible power supplies (UPS) for domestic or small office equipment
Alarm systems and security panels
Emergency and exit lighting fixtures
Portable power packs and small renewable energy or off-grid devices

For standby use, keep the battery charged periodically and avoid deep discharges to prolong service life. Store the battery in a cool, dry place and follow safety instructions regarding short-circuit prevention, ventilation and recycling.
Usage recommendations
