Yuasa Lead-acid battery with 12V and 24Ah - NP24-12I VdS
Description
Product information
The Yuasa NP24-12I VdS is an industrial, valve-regulated lead-acid battery (VRLA) with 12 V nominal voltage and 24 Ah capacity. With leak-proof AGM technology, high current carrying capacity, and VdS approval, this maintenance-free battery is the reliable energy source for safety-critical applications such as fire alarm systems, UPS systems, or telecommunications installations.
Highlights at a glance
- Reliable capacity: 24 Ah (20h) / 22.3 Ah (10h) at 12 V for constant power supply
- Certified: VdS approval for safety-relevant systems
- High peak load: Maximum discharge current up to 500 A for 1 second
- Maintenance-free: AGM technology with > 99 % gas recombination
- Flexible installation: Female thread or bolt connections (M5) with 2.45 Nm tightening torque
Powerful solution for critical systems
With a nominal capacity of 24 Ah (20h discharge to 1.75 V/cell) and 22.3 Ah (10h discharge to 1.8 V/cell), the NP24-12I ensures reliable and stable power supply – even during sudden load peaks up to 500 A. Ideally suited for emergency power supplies, security technology and communication systems where reliability is the highest priority.
Robust technology with high operational reliability
The maintenance-free AGM technology (Absorbent Glass Mat) completely contains the electrolyte in the separator, so no free electrolyte is present. With gas recombination of over 99 % and self-closing safety valves, the battery is safe in operation and does not need topping up. The low self-discharge of about 3 % per month makes it particularly stable in storage.
The robust ABS plastic housing complies with UL94:HB, and a flame-retardant version in accordance with UL94:V0 is available on request.

FAQs about the Yuasa lead-acid battery with 12V and 24Ah
For which applications is the NP24-12I suitable?
It is ideal for fire detection systems, UPS systems, emergency lighting, telecommunications, security technology and PV backup systems.
What is the typical service life in standby mode?
The NP24-12I offers a service life of up to 5 years at 20 °C and is classified as "Standard Commercial" according to EUROBAT.
What type of connection is used?
Female thread or bolt connections (M5) with a tightening torque of 2.45 Nm ensure a secure and vibration-resistant connection.
Is the battery really maintenance-free and leak-proof?
Yes. VRLA technology with gas recombination and valve-regulated design. Each cell has a low-pressure valve. yuasa.de
In which position may the NP24-12I be installed?
Installation and operation possible up to 90 degrees from the upright position. Permanent overhead installation is not intended.
Which charging voltages must be observed and how high may the charging current be?
- Float charge at 20 °C 13.65 V per block.
- Cyclic charge at 20 °C 14.5 V per block.
- Temperature compensation Float about −3 mV per cell and °C, cyclic about −4 mV per cell and °C. Cyclic charging current up to 6 A.
Can the battery be operated in a closed housing?
No, VRLA batteries can emit hydrogen gas. Installation in hermetically sealed enclosures is not permitted and adequate ventilation must always be ensured.
