DBTLAP CMOS RTC Battery for Sony VAIO PCG-C1VN

SKU CH-ZEF4-FEDXE

Lithium CMOS RTC battery replaces the motherboard clock cell on Sony VAIO PCG-C1VN laptops

  • Battery TypeLithium
  • Direct motherboard compatibility for Sony VAIO PCG-C1VN
  • Lithium chemistry provides stable CMOS power retention
  • Pre-tested unit ensures reliable BIOS clock function
  • Single replacement battery restores system time accuracy
  • New condition guarantees full rated service life

Product Identity

This DBTLAP CMOS RTC battery is a direct replacement for the Sony VAIO PCG-C1VN laptop. It restores the system clock and BIOS settings when the original coin cell is exhausted. The lithium chemistry provides stable voltage for real-time clock circuitry. It is intended for technicians or owners servicing this specific model.

Build Integration

The cell slots onto the motherboard header without cables or adapters. No soldering is required, freeing the builder from rework risk. Each unit is tested before shipping to reduce dead-on-arrival incidents. It addresses only the CMOS function and does not power the main laptop battery.

Sustained Behaviour

Lithium chemistry delivers a flat discharge curve over years of continuous trickle draw. The voltage remains within specification throughout the service life, preventing CMOS checksum errors on cold boots. Leakage resistance protects the motherboard from electrolyte damage during extended storage periods.

Highlights

  • Direct motherboard compatibility for Sony VAIO PCG-C1VN
  • Lithium chemistry provides stable CMOS power retention
  • Pre-tested unit ensures reliable BIOS clock function
  • Single replacement battery restores system time accuracy
  • New condition guarantees full rated service life

Questions about this item

What limits the battery life under continuous motherboard standby?

The lithium cell chemistry and self-discharge rate determine how long the CMOS settings are retained when the laptop is unplugged.

Does the battery produce any audible noise or measurable heat while installed?

No. The cell is passive and draws only micro-amps, so it runs silently and at ambient temperature.

Must the laptop already have a two-pin CMOS header and the original battery connector?

Yes. The replacement plugs directly into the existing motherboard header; no extra cables or adapters are required.
