Yuasa 12V 24Ah VRLA Battery, Flame Retardant ABS Case NP24-12IFR
About this product
The Yuasa NP24-12IFR is a 12V 24Ah valve regulated lead acid (VRLA) battery with a flame retardant ABS housing. It suits installers and maintainers where a flame retardant 12V battery is asked for, on standby or cycle use. It measures 166 x 175 x 125 mm and weighs 8.65 kg.
Key features
- Flame retardant housing – ABS UL94-VO for the case and lid
- 12V power in a compact block – 12 V nominal and 24.00 Ah in 20h
- Standby life to plan around – 5 years design life at 20°C on standby use
- Cycle counts stated – 100 cycles at 100% depth of discharge and 700 cycles at 30%
- Designed not to leak – can be operated, charged or stored in any position without leakage, but not charged with the terminals downward
- Slow loss in storage – charge retention of 3% per month at 20°C
For installers
- Power: 13.65 V floating with no current limit needed, and 14.82 V cyclic with maximum current limited to 0.25C, both at 20°C.
- Mounting: 166.0 x 175.0 mm, 125.0 mm overall height, 8.65 kg. Any position, but not charged with the terminals downward.
- Cabling: tightening torque 2.5 Nm (max: 6 Nm).
- Compatibility: check the equipment's own battery and charging figures against this one, and choose a suitable charger.
- Standards: housing material ABS UL94-VO.
Frequently asked questions
What size is the NP24-12IFR?
166.0 mm long, 175.0 mm wide and 125.0 mm in overall height. It weighs 8.65 kg.
What does FR mean on a battery?
FR stands for flame retardant. Here the case and lid are ABS rated UL94-VO.
What charge voltage does it need?
13.65 V for floating and 14.82 V for cyclic use, both at 20°C. Cyclic charging has its maximum current limited to 0.25C.
Can it be fitted on its side?
Yes. It can be operated, charged or stored in any position without leakage, as long as it is not charged with the terminals downward.
How long does it last?
The design life is 5 years on standby use at 20°C. On cycle use it depends on depth of discharge, from 100 cycles at 100% to 700 cycles at 30%.
Does it need topping up with water?
No. It has sealed construction with a pressure relief system, so there is nothing to top up.
