Bateria de chumbo-ácido selada Yuasa RE7-12 12V 7Ah AGM para sistemas de backup e alimentação

Yuasa RE7-12 is a sealed lead acid (SLA) battery with absorbent glass mat (AGM) technology, providing a nominal voltage of 12V and a rated capacity of 7Ah. The valve-regulated, maintenance-free construction ensures spill-proof operation and extended shelf life, making it suitable for small backup power applications. Its compact dimensions allow easy installation in UPS units, emergency lighting assemblies, alarm systems and other enclosed power systems where reliable standby energy is required.

Advantages

The Yuasa RE7-12 combines AGM technology with a valve-regulated design to deliver maintenance-free performance and reduced risk of leakage. Its sealed construction permits upright or horizontal installation in many enclosures while minimizing electrolyte loss and gas emissions under normal use. The battery offers stable voltage delivery during standby and cyclic use, low self-discharge for extended storage, and consistent performance across a wide range of ambient temperatures.

Suitable for

• Uninterruptible Power Supplies (UPS) for small office and home systems
• Emergency and exit lighting systems
• Intrusion and fire alarm panels
• Telecommunications and network backup modules
• Portable and compact power packs for small devices

How to use

Install the battery in a dry, well-ventilated enclosure according to the equipment manufacturer’s instructions, ensuring correct polarity and secure terminal connections. Use an appropriate charger or charger-controller designed for sealed lead acid (AGM) batteries and follow recommended charging voltage and current limits to avoid overcharging. For standby use, connect the battery to the backup input of the UPS, alarm panel or lighting system; for cyclic applications, follow the device manufacturer’s guidance on depth of discharge and recharge cycles.

Recommendations

Store and operate the battery within the manufacturer-recommended temperature range and avoid prolonged exposure to high temperatures. Periodically inspect terminals and connections for corrosion or looseness and ensure charging systems are configured for sealed AGM chemistry. Replace the battery at the end of its service life or when capacity decreases noticeably to maintain reliable backup performance.
