Sealed Lead-Acid Battery PULSAR HPB7-12N 12V 7Ah, maintenance-free VRLA

PULSAR HPB7-12N is a sealed lead-acid (VRLA) battery with a nominal voltage of 12V and a capacity of 7Ah. It is designed as a rechargeable, maintenance-free source of standby and portable power. The battery's leak-proof, valve-regulated construction enables safe use in enclosed spaces and in either upright or side mounting orientations. Typical applications include backup power for alarm systems, UPS units, emergency lighting and portable devices that require stable 12V DC supply.

Advantages

The PULSAR HPB7-12N provides maintenance-free operation thanks to its sealed VRLA design, eliminating the need for regular electrolyte checks. Its compact dimensions and robust casing offer flexible installation options in confined or enclosed equipment housings. The valve regulation ensures controlled gas recombination and reduces the risk of leakage, while the rechargeable chemistry supports repeated charge/discharge cycles for reliable standby performance.

Suitable for

• Backup power for alarm and security systems
• Uninterruptible Power Supply (UPS) modules
• Emergency and exit lighting
• Portable electronic equipment and measurement devices
• Access control panels and small telecom devices

How to use

Before installation, verify that the device requiring power matches the battery's voltage and capacity requirements. Connect the battery using the correct polarity and secure terminals to avoid loose contacts. Charge the battery with a compatible lead-acid battery charger or a charger designed for VRLA chemistry, following the charger manufacturer's settings for 12V lead-acid batteries. For standby applications, keep the battery on float charge to ensure readiness; for cyclic use, follow recommended charge/discharge cycles and avoid deep discharges where possible to extend service life.

Usage recommendations

Store and operate the battery within manufacturer-recommended temperature ranges, avoid exposure to extreme heat or freezing conditions, and ensure adequate ventilation in enclosed installations. Inspect terminal connections periodically and replace the battery when capacity drops below operational requirements.
