UPS battery Sealed Lead Acid Yuasa NP12-12

The Yuasa NP12-12 is a sealed lead acid (VRLA) battery with a nominal voltage of 12 V and a compact design for specialty power applications and UPS systems. The battery uses valve-regulated construction and oxygen recombination technology to minimise maintenance and enable safe, reliable operation. Its sealed casing prevents electrolyte leakage and allows use in most orientations, making it suitable for standby and cyclic power roles.

Advantages

Valve-regulated sealed construction ensures maintenance-free operation and prevents electrolyte leakage. The oxygen recombination and electrolyte suspension systems improve recovery after deep discharge and reduce gas emissions. A pressure venting system releases excess gas if necessary, while lead-calcium grids and superior energy density contribute to extended service life and consistent performance in float or cyclic use.

Suitable for

• Uninterruptible Power Supplies (UPS)
• Standby and emergency power systems
• Telecommunications backup
• Security and alarm systems
• Portable and specialty power applications requiring a 12 V VRLA battery

Key specifications

• Nominal voltage: 12 V
• Battery type: Sealed lead acid (VRLA), valve-regulated
• Weight: 4.05 kg
• Construction: sealed casing, usable in any orientation except continuous inverted
• Features: oxygen recombination, electrolyte suspension system, pressure venting
• Use modes: float (standby) or cyclic operation

How to use

Install the battery according to the equipment manufacturer’s instructions, observing correct polarity and secure mounting. Use a compatible charger or UPS charging circuit configured for sealed lead acid batteries and follow recommended charging voltages for float and cyclic modes. Do not operate continuously in an inverted position. Periodically inspect the battery and installed connections for corrosion or loose terminals, and ensure the venting area is not obstructed.

Recommendations

Store the battery in a cool, dry place and, if stored for extended periods, perform periodic charging every few months to maintain capacity. Use this battery in applications that match its 12 V VRLA characteristics and follow the device and charger manufacturer guidelines for best life and performance.
