Yuasa NP2.3-12 VdS industrial battery 12 V 2.3 Ah
Description
Product information
The Yuasa NP2.3-12 is a maintenance-free VRLA industrial battery with VdS approval. It impresses with its compact dimensions, reliable power delivery and a service life of up to 5 years. Ideal if you need a stable 12-volt supply in a compact space for safety and emergency power applications.
Highlights at a glance
- Reliable capacity: 2.3 Ah at 20-hour discharge down to 10.5 V at 20 °C.
- Compact and lightweight: 178 x 34 x 64 mm at 0.95 kg.
- Flexible mounting: Operation in any position except permanently upside down.
- Low self-discharge: About 3 percent per month at 20 °C.
- Especially safe: Low pressure relief valves, UL recognised materials.
- Easy installation: FASTON plug-in connection 4.7 mm.
Maximum performance for compact applications
Despite its small size, the NP2.3-12 delivers high charging currents for short periods. Up to 69 A for 1 second and 23 A for 1 minute are possible. The measured internal resistance is 90 mΩ at 1 kHz. This makes the battery particularly suitable for fire and intruder alarm systems, emergency and safety lighting, controllers, measuring instruments as well as small UPS and buffer applications.
Efficiency meets long service life
The EUROBAT classification as Standard Commercial stands for a typical service life of 3 to 5 years at 20 °C. The low self-discharge supports long service times. The housing is made as standard from ABS to UL94 HB, with an optionally available flame-retardant FR version to UL94 V0. Valve-regulated recombination and low-maintenance operation ensure high operational safety.
Technology for flexible applications
The battery can be operated in almost any position except permanently upside down. The operating temperature range for charging and discharging is minus 20 °C to plus 60 °C. For float charging, 13.65 V ±1 percent is provided, with temperature compensation of minus 3 mV per cell and degree Celsius. For fast charging, 14.50 V ±3 percent applies, compensation minus 4 mV per cell and degree Celsius.
For float charging, no current limitation is required, for fast charging 0.575 A is recommended. Sufficient ventilation must be ensured, as hydrogen can be produced with VRLA batteries.
Electrical connection is via FASTON 4.7 mm plug-in connectors. The compact design facilitates installation in narrow housings and racks.

FAQs about the Yuasa NP lead battery
For which applications is the battery suitable?
Preferred areas of application are VdS-compliant fire and intruder alarm systems, emergency and safety lighting, control and signalling systems, measuring instruments, small UPS and buffer applications.
How is the battery installed?
Mounting is possible in any position except permanently upside down. Electrical connection is via FASTON blade terminals 4.7 mm. Please ensure correct polarity and sufficient ventilation.
What charging voltage is recommended?
- For float charging 13.65 V ±1 percent at 20 °C, temperature compensation minus 3 mV per cell per °C.
- For fast charging 14.50 V ±3 percent at 20 °C with compensation minus 4 mV per cell per °C.
- No current limitation required for float charging, for fast charging 0.575 A.
Are there any special safety instructions?
Each cell has a low pressure valve for controlled venting. Do not operate batteries in gas-tight housings. Dispose of at the end of service life according to local regulations.
Ask ChatGPT
Is the battery suitable for series and parallel connections?
Basically yes, provided installation is carried out according to Yuasa guidelines. Observe identical cable lengths per strand, suitable fuses, correct polarity and sufficient ventilation. For multiple strands, follow the instructions for multi-strand connection.
Which chargers are suitable?
Chargers with constant voltage for VRLA-AGM, set to the voltages specified in the data sheet and taking temperature compensation into account.
