DBTLAP CR2032 CMOS Battery for IBM 08K8216 08K8050 02K6541 92P0986

SKU CH-2BED-N0DMG

CR2032 lithium CMOS battery replaces IBM part numbers 08K8216, 08K8050, 02K6541 and 92P0986 to maintain BIOS settings

  • Battery typeLithium
  • CR2032 lithium chemistry keeps BIOS settings alive during power loss
  • Replaces IBM part numbers 08K8216, 08K8050, 02K6541 and 92P0986
  • Tested before shipping so the RTC circuit works on first boot
  • Single-cell design fits standard motherboard holders without adapters
  • New condition guarantees full rated capacity from day one

What this product is

This is a CR2032 lithium CMOS battery manufactured by DBTLAP for IBM laptop motherboards. It replaces the original BIOS RTC cell when the system clock loses time or the BIOS settings reset. The battery is new and tested before shipping. It is not a main laptop power pack and cannot run the computer.

How it fits into a build

The cell slots into the motherboard holder that previously held IBM part numbers 08K8216, 08K8050, 02K6541 or 92P0986. No soldering or additional cables are required for installation. It frees the board from a dead backup source so the real-time clock and CMOS memory retain data while the laptop is off. Builders who need a rechargeable main battery or a different form factor cannot use this item.

Behaviour under sustained load

The lithium chemistry delivers a steady low current to the real-time clock circuit over years rather than high bursts. Voltage remains stable during the long intervals between mains-powered sessions. The cell is not designed for heavy discharge cycles and will not support components that draw significant power.

Questions about this item

How long does the CR2032 CMOS battery last before the system clock drifts?

The lithium CR2032 cell typically maintains BIOS settings for 2 to 5 years under normal use before voltage drops enough to lose the real-time clock.

Does the battery generate noticeable heat or noise during continuous operation?

No, the CR2032 is a passive lithium coin cell with no moving parts; it produces zero noise and negligible heat while powering the RTC circuit.

Which IBM laptop models use the 08K8216, 08K8050, 02K6541 or 92P0986 part numbers?

This battery replaces IBM FRUs 08K8216, 08K8050, 02K6541 and 92P0986; verify your service manual to confirm the exact model match.
