Description

WhisperPower 2V – 1650 Ah (OPzV valve regulated) batteries are perfect for applications needing prolonged deep charge and discharge cycles. Fully maintenance-free, these GEL batteries use tubular plate technology to keep the electrolyte contained in the GEL. They are commonly employed in emergency power supplies, marine and mobile battery banks, and UPS systems.

  • Designed to last for over 10 years
  • Suitable for high charge current (50% of nominal capacity)
  • Ideal battery for large battery banks (600 to 8000 Ah)
  • Best option for intensively used heavy duty inverter(s)
  • Suitable for a large number of charge cycles (1200 to 3000 depending on dis- charge level)
  • 7 year warranty (Restricted to cycles)
