## Long description

Sealed Lead-Acid Battery BrightSign 12V 20Ah T12(M5) Pb AGM is a maintenance-free rechargeable battery with a nominal voltage of 12 V and a capacity of 20 Ah. The battery uses absorbent glass mat (AGM) technology, which immobilizes the electrolyte to reduce leakage risk and allow installation in multiple orientations. T12(M5) terminal connectors provide secure mechanical and electrical contact for applications that require stable power delivery over long standby periods.
Advantages
The BrightSign 12V 20Ah battery is maintenance-free and sealed, eliminating the need to add water and minimizing routine service. AGM construction offers low internal resistance, consistent discharge characteristics and improved vibration resistance compared with flooded lead–acid cells. T12(M5) terminals ensure reliable connection compatibility with common UPS, alarm and portable power housings. The design supports long shelf life and stable self-discharge rates, making it suitable for periodic use and standby power systems.
Suitable for
 Uninterruptible Power Supplies (UPS) for consumer and small business equipment

How to use
Install the battery in a well-ventilated enclosure compatible with sealed lead–acid batteries and ensure correct polarity when connecting to the system. Tighten the T12(M5) terminals to the torque recommended by the equipment manufacturer, avoiding over-tightening that can damage the faston connections. Charge the battery with a charger or power supply designed for lead–acid AGM batteries, following recommended charge voltages and temperature compensation if applicable. For long-term storage, store the battery in a cool, dry place and apply periodic float or equalization charging as specified by the system integrator to maintain capacity.
Usage recommendations
To maximize service life, avoid deep discharges where possible and use a charger with AGM-compatible charge profiles. Replace batteries in matched sets when used in parallel or series configurations, and follow local regulations for disposal or recycling of lead–acid batteries.
