Yuasa REC22-12I Cyclic industrial battery 12 V 22 Ah
Product information
The Yuasa REC22-12I is a cycle-resistant VRLA industrial battery. It supplies 12 volts and 22 Ah (at 20 hours) and features a high cycle life, low impedance and stable power output in a compact design. It is ideally suited for a wide range of applications, including mobile devices, cleaning machines, rehabilitation and medical technology, photovoltaic buffering, measurement and control technology, as well as UPS systems in cyclic operation.
Highlights at a glance
- Cycle-resistant: Up to 1400 cycles at 25 percent DOD
- Reliable capacity: 22 Ah at 20-hour discharge to 10.5 V, 19.7 Ah at 10-hour discharge to 10.8 V.
- Flexible installation: Operation possible in any position, except permanently upside down.
- Low self-discharge: About 3 percent per month at 20 °C.
- Case material: ABS to UL94 HB.
Maximum performance for demanding cycle applications
The REC22-12I is designed for repeated charging and discharging operations. AGM technology and valve-regulated oxygen recombination ensure efficient gas retention and low maintenance requirements. Low impedance supports high peak currents, so sensitive loads are reliably supplied even with dynamic load profiles.
Efficiency meets long service life
In standby operation, a float charge voltage of 13.65 V ±1 percent per block is applied, which is adjusted by a temperature compensation of minus 3 mV per cell and degree Celsius. For cyclic or boost charging, 14.52 V ±3 percent per block is provided, with compensation of minus 4 mV per cell and degree Celsius. The recommended current limit is 5.5 A in both float and cyclic operation. The service life in use is confirmed by the EUROBAT classification General Purpose 6 to 9 years and a Yuasa Design Life specification of 7 years at 20 °C.
Technology for flexible applications
The operating temperature range includes discharge from -15 °C to +40 °C, charging from 0 °C to +40 °C and storage from -15 °C to +50 °C. Each cell is equipped with a low pressure relief valve. As VRLA batteries release hydrogen, it is important not to operate them in gas-tight enclosures and to ensure adequate ventilation.
