Product Features

Reliable General-Purpose Power

This 12V 7Ah battery delivers consistent, maintenance-free power for a wide range of standby and cyclic applications. Its sealed lead-acid (SLA) design ensures safe operation without the need for watering, making it ideal for use in UPS systems, alarms, and other electronic devices requiring backup power.

Optimized Capacity and Discharge Performance

Rated at 7.0Ah over a 20-hour discharge rate, the battery provides reliable runtime. Performance data across multiple discharge rates (from 20-hour to 15-minute) is clearly specified, allowing for accurate runtime calculations based on the specific load profile of your application.

Robust Construction and Standard Terminals

Built with a durable case, the battery features industry-standard F1/F2 style terminals, ensuring compatibility with a wide array of connectors and wiring harnesses commonly used in backup power systems. This design facilitates straightforward installation and replacement.

Stable Temperature Performance

The battery maintains operational capacity across a range of temperatures, with specified performance at 40°C (102% of rated capacity), 25°C (100%), 0°C (85%), and -15°C (65%). For optimal lifespan, it is recommended to avoid prolonged operation above 40°C.

Low Self-Discharge for Extended Shelf Life

Exhibiting a low self-discharge rate, the battery retains approximately 91% of its capacity after 3 months of storage at 20°C. This characteristic is beneficial for standby applications and ensures the battery remains ready for use after periods of inactivity.

Clear Charging Guidelines

The specifications provide precise charging parameters for both cyclic (14.4V–14.7V) and float (13.5V–13.8V) applications at 25°C. Following these voltage guidelines with a current limit under 2.1A is essential for maximizing the battery’s cycle life and maintaining its health.
