DBTLAP CMOS Battery for Dell Precision M4700

SKU CH-C8VN-GE5DA

A lithium CMOS battery that keeps the system clock and BIOS settings on a Dell Precision M4700

  • Battery TypeLithium
  • Keeps system time accurate with dedicated CMOS lithium cell
  • Direct replacement for Dell Precision M4700 motherboard battery
  • Restores BIOS settings retention after original cell fails
  • Pre-tested unit ensures reliable operation on installation
  • Single battery packaged for immediate motherboard fit

Compatible Dell Precision M4700 CMOS Battery

The DBTLAP lithium CMOS battery is a direct replacement for the Dell Precision M4700 motherboard RTC clock. It restores BIOS settings retention and accurate system time when the original cell fails. This component is for laptop motherboards only and is not a main laptop power battery. Buyers needing a primary system battery will not find it here.

New Lithium Cell Tested Before Shipping

Each unit is new and verified by the supplier before dispatch to ensure reliable voltage delivery. The lithium chemistry provides stable low-current output for the real-time clock circuit during normal standby and daily operation. No active cooling or power management is involved because the draw is minimal. There are no noise or thermal concerns associated with this passive component.

Sustained RTC Power Retention

Under continuous load the cell maintains the CMOS memory and clock without interruption for the duration of its rated lifespan. It is designed to hold charge across extended powered-off periods typical of laptop storage. The battery supports the motherboard firmware reliably until its natural end of life. Builders requiring a higher-capacity or rechargeable main system pack should look elsewhere.

Questions about this item

How do I install the CMOS battery in a Dell Precision M4700 and which step is often missed?

Remove the old cell from its holder on the motherboard, insert the new lithium battery with the positive side facing up, then enter BIOS to reset the date and time — the step most users forget.

What maintenance will this CMOS battery need later?

The lithium cell requires no routine maintenance; when the system clock drifts or BIOS settings stop saving, simply replace the battery with an identical type.

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

The cell's chemical life is the limiting factor; after several years of continuous power to the real-time clock, voltage drops and the motherboard can no longer retain BIOS settings.
