GEL Battery 2 V – 210 Ah
Additional information
Description
WhisperPower 2 V – 210 Ah (OPzV valve regulated) batteries are ideally suited for applications with extended deep charge / discharge cycles. They are fully maintenance free. These 2 V – 210 Ah GEL batteries are constructed using tubular plate technology, wherein the electrolyte is contained in the GEL. They are widely used in emergency / back-up power supplies, marine and mobile 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)
