## Long description

RTC Battery Lenovo FRU00HN615 is a rechargeable replacement real-time clock battery intended for compatible Lenovo laptops. Designed to maintain the system clock and BIOS configuration when the main battery or power source is disconnected, this unit supports system stability during maintenance and prolonged periods without external power. The rechargeable design allows the module to retain settings over multiple discharge/charge cycles, ensuring date, time and BIOS parameters remain intact after component replacements or service operations.
Advantages
The battery preserves BIOS settings and system time reliably while the laptop is powered down or the primary battery is removed. Its rechargeable nature reduces the need for frequent replacements and supports repeated service cycles. The compact form factor fits into designated RTC compartments on supported Lenovo models and allows for straightforward installation during repairs. Using a manufacturer-compatible replacement helps maintain system compatibility and reduces the risk of configuration loss.
