## Long description

RTC backup battery Lenovo 01AW186 is a 3.0V 2200mAh rechargeable cell engineered to sustain a computer or embedded device realtime clock and to preserve BIOS/CMOS settings during power interruptions. The cell’s compact cylindrical form and low self-discharge chemistry make it suitable for long-term standby duty in systems that require continuous clock operation and retention of configuration data when main power is removed.
Advantages
The battery provides reliable voltage for RTC circuits and CMOS memory, offering extended backup time thanks to its 2200mAh capacity. Its rechargeable construction reduces the need for frequent replacements in serviceable devices. Small size and standardized electrical characteristics simplify installation into compatible Lenovo and other systems that accept the same cell format. Low self-discharge properties help maintain charge over long storage periods, ensuring the realtime clock remains accurate after prolonged downtime.
Suitable for
Maintaining system clock and BIOS/CMOS settings in Lenovo desktop and embedded systems
Replacement in motherboards and industrial controllers that use a 3.0V RTC cell
Service and maintenance of devices where long-term standby battery is required
Key specifications
Nominal voltage: 3.0 V
Capacity: 2200 mAh (rechargeable)
Chemistry: rechargeable cell optimized for low self-discharge
Physical format: compact cylindrical RTC backup cell suitable for CMOS/BIOS modules
Intended use: realtime clock and CMOS memory backup in computers and embedded devices
How to use
Before installation, power down the device and disconnect it from mains power. Access the motherboard or RTC module according to the device service manual and remove the depleted cell, taking electrostatic discharge precautions. Install the replacement cell in the correct polarity orientation and secure it in the holder or compartment.
