GEL Battery 2 V – 750 Ah
Additional information
Description
WhisperPower 2V – 750 Ah (OPzV valve regulated) batteries excel in applications demanding extensive deep charge and discharge cycles. These GEL batteries, which require no maintenance, feature tubular plate technology to encapsulate the electrolyte in the GEL. They are often used in emergency power systems, marine battery banks, and UPS installations.
- 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)
