Yuasa Lead-acid battery with 12V and 24Ah - NPC24-12I

The Yuasa NPC24-12I is a cyclic, valve-regulated lead-acid battery (VRLA) with 12 V nominal voltage and 24 Ah capacity. Thanks to its optimised AGM technology, high cycle stability and robust design, this maintenance-free battery is ideal for applications with frequent charging and discharging processes such as electric vehicles, cleaning machines or mobile energy supply systems.

Highlights at a glance

• High capacity: 24 Ah (20h) / 22.2 Ah (10h) for reliable power supply
• Long service life in cyclic operation: Up to 1,400 charge/discharge cycles (at 25 % DOD)
• High peak load: Maximum discharge current up to 500 A (1 second)
• Maintenance-free: VRLA-AGM technology with > 99 % gas recombination
• Flexible mounting: Female thread or bolt connections (M5) with 2.5 Nm tightening torque

Cycle-proof energy source for demanding applications

The NPC24-12I is designed for frequent charging and discharging cycles and achieves, depending on the depth of discharge:

• 1,400 cycles at 25 % DOD
• 600 cycles at 50 % DOD
• 500 cycles at 75 % DOD
• 300 cycles at 100 % DOD

With a peak current output of up to 500 A (1 second) and 240 A (1 minute), the battery offers stable performance even during short-term load peaks.

Robust technology with safe operation

The leak-proof AGM (Absorbent Glass Mat) design binds the electrolyte completely in the separator, prevents liquid from escaping and ensures a gas-tight seal with self-closing safety valves. Self-discharge is only approx. 3 % per month, making the battery suitable for longer standby phases.

The robust ABS housing fulfils the UL94:HB standard and is optionally available in a flame-retardant version in accordance with UL94:V0.

Battery features

FAQs about the Yuasa lead-acid battery with 12V and 24Ah

For which applications is the NPC24-12I suitable?

This battery is specially designed for cyclic applications such as electric vehicles, cleaning machines, mobile power supplies, leisure and marine applications and renewable energy systems.

How many charge cycles does the battery achieve?

The typical service life in cycles up to 80 % remaining capacity: 300 cycles at 100 % DoD, 500 at 75 % DoD, 600 at 50 % DoD, 1400 at 25 % DoD.

How safe is the operation?

The battery is valve-regulated, gas-tight sealed, maintenance-free and equipped with self-closing drain valves. Operation is possible in any position – except permanently upside down.

Which connection type is used?

Internal thread or bolt connections (M5) with 2.5 Nm tightening torque ensure a secure and vibration-resistant connection.

What charging voltages and currents must be observed?

• Trickle charge at 20°C: 13.65 V per block, temperature compensation −3 mV per cell and °C.
• Cyclic charging at 20°C: 14.5 V per block, temperature compensation −4 mV per cell and °C.
• Current limitation for cyclic charging: 6 A. No current limitation is required for trickle charging, provided voltage-limited charging is used.

What operating temperatures apply?

Charging −15 to +50 °C, discharging −20 to +60 °C, storage −20 to +60 °C.
