Yuasa Lead-acid battery with 12V and 12Ah – NP12-12 VDS
Product information
The Yuasa NP12-12 VDS is a high-quality, valve-regulated lead-acid (VRLA) battery with a nominal voltage of 12 volts and a capacity of 12 Ah. Featuring maintenance-free AGM technology and VdS certification, this battery provides a reliable and long-lasting power supply for safety-critical and industrial applications. Whether in standby mode or in cyclic use, the NP12-12 meets the highest quality and safety standards.
Highlights at a glance
- High capacity: 12 Ah at 12 V for a long-lasting power supply.
- VdS approved: G 189170 for safety-related applications
- Maintenance-free: Leak-proof AGM technology with > 99% gas recombination.
- High current-carrying capacity: Up to 360 A discharge current for 1 second.
- Flexible installation: Operation in all positions (except permanently upside down).
- Long-lasting: EUROBAT class “Standard Commercial” with a service life of up to 5 years.
High performance for safety-critical applications
The NP12-12 delivers 12 Ah during a 20-hour discharge (down to 1.75 V/cell) and 11.1 Ah during a 10-hour discharge (down to 1.8 V/cell). With a maximum discharge current of 360 A for 1 second and 75 A for 1 minute, this battery is also ideally suited to short-term power peaks.
Robust technology for demanding environments
Thanks to VRLA (Valve Regulated Lead Acid) technology with an AGM (Absorbent Glass Mat) system, the NP12-12 is completely maintenance-free and leak-proof. The battery features self-closing low-pressure relief valves for safe pressure equalisation within the cells. The internal resistance is 44.39 mΩ in accordance with EN IEC 60896-21, and the short-circuit current is 320 A.
The low self-discharge rate of approx. 3% per month allows for long-term storage whilst maintaining a high state of readiness. The robust ABS housing can also be supplied in a flame-retardant version (UL94:V0) on request.
