Targeted replacement for Sony VAIO VGN-AR71S

This DBTLAP CMOS battery is built specifically for the Sony VAIO VGN-AR71S motherboard. It restores the real-time clock and BIOS settings when the original cell fails. The lithium chemistry provides stable voltage for firmware retention. It is not a main laptop battery and will not power the system itself.

Simple two-wire installation with polarity care

The unit arrives pre-tested and ready to fit into the motherboard header. Installation requires only disconnecting the old cell and plugging in the new connector. The main risk is reversing the polarity, which can damage the CMOS circuitry. No soldering or special tools are needed for the swap.

Limited to CMOS backup duty only

This cell supplies the low current needed for the real-time clock and configuration memory. It cannot support any system load or peripheral power. Capacity is fixed by the lithium chemistry and form factor. Builders needing extended main-system runtime must look elsewhere.
