Description
The WhisperPower AGM Battery 12 V – 80 Ah is the most economical, maintenance-free battery designed for long life. WhisperPower 12 V – 80 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.
