SKU CH-JV64-5ZGBX

Lithium CMOS battery replaces the BIOS RTC cell in Sony Vaio VGN-AR730 laptops

  • Battery TypeLithium
  • Designed for Sony Vaio VGN-AR730 motherboard compatibility
  • Lithium chemistry delivers reliable CMOS power retention
  • Replaces faulty or cracked BIOS RTC batteries
  • Each unit tested before dispatch for quality assurance
  • Package includes one ready-to-install CMOS battery

Compatible Sony Vaio VGN-AR730

This DBTLAP CMOS battery is a direct replacement for the Sony Vaio VGN-AR730 laptop motherboard. It restores the real-time clock and BIOS settings when the original cell fails. The lithium cell arrives new and tested, ready for installation. It is not a main laptop power battery.

Sustained timekeeping reliability

Under continuous low-drain operation the lithium chemistry maintains a stable voltage for the CMOS circuit. The cell keeps the system clock accurate and preserves BIOS configuration during long periods when the laptop is unplugged or powered off. It is tested before shipping to verify correct output.

Replaces a dead or leaking CMOS cell

This part upgrades a faulty, cracked or exhausted original battery that causes date resets or BIOS errors. The jump is worth it when the laptop loses time settings after shutdown or displays CMOS checksum warnings. Buyers needing a main rechargeable laptop battery should look elsewhere.

Questions about this item

Will the CMOS battery on my VGN-AR730 run hot or draw extra power if left on continuously?

The lithium CMOS cell only powers the real-time clock and BIOS memory when the laptop is off, so it generates no noticeable heat and consumes negligible power during all-day use.

Does the DBTLAP CMOS battery for the VGN-AR730 need any extra cables or connectors to install?

The battery ships as a direct replacement with its original connector attached, so no additional cables or adapters are required for installation.

Can I keep my older Sony Vaio motherboard and just swap in this CMOS battery?

Yes, the cell is built to match the VGN-AR730 motherboard specifications, letting you retain the existing board while restoring BIOS settings and clock accuracy.
