DBTLAP CMOS Battery Compatible for Dell Precision M65

SKU CH-R7V7-CPB99

Lithium CMOS battery replaces the faulty RTC cell on Dell Precision M65 motherboards

  • Battery TypeLithium
  • Compatible replacement for Dell Precision M65
  • Lithium coin cell maintains BIOS settings
  • Tested before shipping for reliability
  • High-quality construction resists leakage
  • Single unit ready for motherboard installation

Direct Dell Precision M65 CMOS replacement

This lithium coin cell restores the real-time clock and BIOS settings on a Dell Precision M65 motherboard. It is a dedicated CMOS battery, not a main laptop battery, and arrives new and tested. Install it when the system loses time or shows CMOS checksum errors.

Low self-discharge lithium chemistry

The cell holds its voltage for years inside the chassis with negligible current draw. No active cooling or power management is involved because the battery only powers the RTC when the laptop is off. Operation is silent and adds no measurable heat.

Fits Dell Precision M65 only

Compatibility is limited to the Precision M65 model; the connector and form factor will not suit other Dell laptops or desktop boards. Buyers needing a CMOS cell for a different Precision series or for a non-Dell machine must source the correct part number.

Highlights

Questions about this item

How do I install this CMOS battery on the Dell Precision M65 motherboard?

Locate the coin-cell socket on the motherboard, remove the old cell, insert the new lithium battery with the correct polarity, then reset the BIOS date and time.

What maintenance or replacement will this CMOS battery need later?

The lithium CMOS battery typically lasts several years; replace it when the system loses BIOS settings or shows a real-time clock error on boot.

What limit appears first under sustained use of this CMOS battery?

The lithium chemistry gradually depletes, so the battery will eventually fail to maintain the real-time clock and CMOS settings during power-off periods.
