About this product
The Yuasa NP24-12I is a 12V 24Ah valve regulated lead acid (VRLA) battery for general purpose use. It suits installers and maintainers who need a larger 12V battery on float or cyclic charge. It measures 166 x 175 x 125 mm, weighs 9 kg and has M5 female threaded terminals.
Key features
- 12V power in a standard block – 12 V nominal and 24 Ah at the 20-hr rate
- No free acid inside – Absorbed Glass Mat construction
- Comes back after heavy use – good recovery from deep discharge
- Fits awkward spaces – can be installed and operated in any orientation except permanently inverted
- Planned service life – EUROBAT Standard Commercial 3 to 5 years, Yuasa design life up to 5 years at 20°C
- Slow loss in storage – capacity loss of about 3% per month at 20°C
For installers
- Power: float charge 13.65 (±1%) V at 20°C with no current limit. Cyclic or boost charge 14.5 (±3%) V at 20°C, limited to 6 A.
- Mounting: 166 (±1) x 175 (±1) mm, 125 (±2) mm high, 9 kg. Any orientation except permanently inverted.
- Cabling: Threaded terminal, M5 (F), female. Torque 2.45 Nm.
- Compatibility: check the equipment's own battery and charging figures against this one, and use a charger that matches them.
- Standards: EUROBAT Standard Commercial 3 to 5 years, with ISO9001, ISO14001 and ISO45001 certifications.
Frequently asked questions
What size is the NP24-12I?
166 (±1) mm long, 175 (±1) mm wide and 125 (±2) mm high. It has a mass of 9 kg.
What charge voltage does it need?
13.65 (±1%) V on float and 14.5 (±3%) V for cyclic or boost charging, both at 20°C. Use a charger set for lead acid batteries.
Can it be mounted on its side?
Yes. It can be installed and operated in any orientation except permanently inverted.
Can it go in a sealed box?
No. VRLA batteries release hydrogen gas which can form explosive mixtures in the air, so it must not be placed inside a sealed container.
How long does it last?
Yuasa gives a design life of up to 5 years at 20°C, and EUROBAT classes it Standard Commercial, 3 to 5 years. Heat and repeated deep discharge usually shorten real service life.
What terminals does it have?
M5 female threaded terminals, with a torque of 2.45 Nm. Your leads need ring terminals or bolted fittings to suit, not push-on tabs.
