WhisperPower AGM Battery 12 V – 145 Ah

The WhisperPower AGM Battery 12 V – 145 Ah is the most economical, maintenance-free battery designed for long life. WhisperPower 12 V – 145 Ah AGM batteries are based on VRLA technology (Valve Regulated Lead Acid), meaning they require little ventilation, do not have to be positioned upright and do not require any maintenance.

• 145 Ah, 12 VDC
• Suitable for medium sized inverters
• Power supply for entire DC installation
• Powering pumps and winches
• Suitable for marine, mobile and solar energy systems- and as a starter battery.
