Description

WhisperPower 2V – 1250 Ah (OPzV valve regulated) batteries are best suited for applications requiring extensive deep charge and discharge cycles. Completely maintenance-free, these GEL batteries are built using tubular plate technology to contain the electrolyte. They are widely utilized 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)
