DBTLAP CMOS Battery for A505 SP6910 SP6986 SP6988 SP6996

SKU CH-JWDF-JT4JP

Replacement lithium CMOS battery for A505 series laptop motherboards, tested before shipping

  • Battery TypeLithium
  • Maintains system time and BIOS settings with lithium CMOS battery
  • Direct replacement for A505 models SP6910 SP6986 SP6988 SP6996
  • Tested before shipping to ensure reliable motherboard operation
  • Fixes faulty or broken CMOS battery to restore boot stability
  • Single lithium cell designed for laptop motherboard RTC function

Compatible Laptop Models

This DBTLAP CMOS battery replaces the RTC BIOS cell in Toshiba Satellite A505 series laptops. It fits models SP6910, SP6986, SP6988 and SP6996 variants. The lithium coin cell restores date, time and BIOS settings when the original battery fails.

Who This Suits

Owners of the listed Satellite A505 models needing a direct replacement for a depleted CMOS battery will find the correct fit. Builders working on other laptop series or desktop motherboards should look elsewhere because the connector and form factor are specific to these part numbers.

Critical Specification

Battery type is lithium, matching the original chemistry required by the motherboard RTC circuit. Using a different chemistry would prevent the real-time clock from keeping accurate time when the main power is removed.

Questions about this item

When will the lithium cell in this CMOS battery need replacing on an A505-SP6986 motherboard?

The lithium CMOS battery maintains RTC and BIOS settings; typical service life spans several years before voltage drops enough to require replacement.

What is the first limit reached when this CMOS battery powers the RTC continuously on an A505-SP6996 system?

The limiting factor is gradual cell depletion; once voltage falls below the threshold needed to retain CMOS data, BIOS settings will be lost on power-off.

Does this CMOS battery generate any noticeable heat or noise during all-day operation in an A505-SP6988 laptop?

No, a lithium CMOS coin cell operates passively with negligible self-discharge current, producing no audible noise and no measurable heat under normal use.
