Sealed Lead-Acid VRLA AGM Battery CARSPA MS4.5-12 12V 4.5Ah for UPS and Backup Power

Sealed Lead-Acid VRLA AGM Battery CARSPA MS4.5-12 provides 12 V nominal voltage and 4.5 Ah capacity in a compact 90×70×101 mm case weighing 1.5 kg. The battery uses VRLA AGM (Valve Regulated Lead Acid, Absorbed Glass Mat) technology, is hermetically sealed and maintenance-free. Its low internal resistance and robust construction make it suitable for high-discharge applications such as starters, inverters and UPS or for standby power in emergency lighting and solar systems.

Advantages

The CARSPA MS4.5-12 offers extended service life compared with many conventional designs, greater shock resistance due to a stronger container construction, and a higher power-to-size ratio that widens its range of applications. The VRLA valve regulates internal pressure and acts as a safety overpressure relief; the sealed AGM design prevents electrolyte leakage when tilted or inverted.

Suitable for

• Uninterruptible power supplies (UPS)
• Emergency lighting systems
• Alarm and security panels
• Small inverters and power converters
• Standby power in solar/renewable systems
