- Long-term operation: EUROBAT class “Long Life” with up to 12 years service life
- Fast discharge possible: 500 A discharge current for 1 second
- Reliable technology: VRLA technology with integrated safety valves
- Fire protection included: Flame-retardant ABS housing according to UL94:V0
Compact, powerful and maintenance-free
With a capacity of 25 Ah (20h rate), the SWL750FR delivers up to 767 W at a 10-minute constant discharge, perfect for applications with a high short-term power requirement. The maintenance-free VRLA technology allows safe and gas-tight operation for many years. Thanks to its robust construction and low weight of only 9.8 kg, the battery can be easily integrated into compact systems.
Efficient energy supply with long service life
The battery belongs to the EUROBAT “Long Life” category with an operating life of 10 to 12 years at 20 °C ambient temperature. Self-discharge is only about 3% per month, ensuring operational readiness even after long storage periods. With a maximum discharge capacity of 500 A (1 second) and 150 A (1 minute), the SWL750FR is ideally suited for peak loads in safety-critical applications.
Flexible installation and certified safety
The battery can be installed in any position except for permanent overhead mounting. Connection is via M5 female thread or bolt connections. The flame-retardant housing material (UL94:V0) as well as the integrated low-pressure valve, which enables safe overpressure compensation in case of gas formation, provide additional safety. The SWL750FR is certified according to ISO 9001, ISO 14001, EN 18001 and by UL.
