WhisperPower 2V – 1500 Ah (OPzV valve regulated) batteries are ideally suited for applications requiring extended deep charge and discharge cycles. These GEL batteries, which are maintenance-free, utilize tubular plate technology to hold the electrolyte in the GEL. They are widely used 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)
