Yuasa Lead-acid battery with 12V and 17Ah - NP17-12I VDS
Description
Product information
The Yuasa NP17-12I VDS is an industrial, valve-regulated lead-acid battery (VRLA) with 12 V nominal voltage and 17 Ah capacity (20h). Thanks to leak-proof AGM technology, high current carrying capacity and VdS certification, this maintenance-free battery is particularly suitable for safety-critical applications such as fire alarm systems, UPS systems or telecommunications.
Highlights at a glance
- High capacity: 17 Ah (20h) / 15.7 Ah (10h) at 12 V for continuous power supply.
- Certified: VdS approval for safety-relevant systems such as fire alarm systems.
- Highly resilient: Up to 500 A discharge current for 1 second.
- Maintenance-free: VRLA-AGM technology with > 99 % gas recombination.
- Robust design: Internal thread or bolt connection (M5) for secure installation.
- Durable: EUROBAT class “Standard Commercial” up to 5 years operating life.
Powerful solution for critical systems
With a capacity of 17 Ah (20h discharge to 1.75 V/cell) or 15.7 Ah (10h discharge to 1.8 V/cell), the NP17-12I supplies reliable power even during sudden loads up to 500 A for 1 second. Ideal for use in safety-critical areas where constant performance and operational safety are decisive.
Robust technology with long service life
The maintenance-free AGM technology (Absorbent Glass Mat) ensures a gas-tight seal with > 99 % gas recombination. The battery does not require electrolyte refilling and features self-closing low-pressure vent valves for safe pressure regulation. Self-discharge is only approx. 3 % per month, ideal for long-term readiness.
The housing is made from durable ABS plastic (UL94:HB), with a flame-retardant version to UL94:V0 available as an option. The M5 internal thread or bolt connections enable stable and secure assembly with a tightening torque of 2.45 Nm.
