CMOS Battery for Dell Latitude E6500
This Cameron & Co lithium CMOS battery replaces Dell part 23.22207.041 and compatible equivalents across Latitude, Precision, Inspiron and select HP, Acer, Compaq, Fujitsu and Medion laptops. It supplies 3.0V and 0.2 Ah to maintain system time and BIOS settings when the main battery is removed. The cell is non-rechargeable and matches the original form factor for direct replacement.
Sustained Load Behaviour
The battery provides a steady 3.0V output over its rated 0.60 Wh capacity to keep the real-time clock and CMOS memory alive during long periods without main power. Voltage remains stable until the lithium chemistry is exhausted, at which point the system will lose date and BIOS configuration. No recharge cycle is supported, so the cell must be replaced once depleted.
Installation and Common Issues
The unit measures 30.10 x 20.12 x 4.12 mm and fits the standard CMOS holder on the listed motherboards. Installation requires opening the chassis, locating the coin-cell socket, and pressing the new cell in with correct polarity. Common problems include inserting the battery backwards, damaging the retaining clip, or failing to clear BIOS checksum errors after the swap. Buyers needing a rechargeable solution or a different voltage cannot use this part.

Questions about this item
How much power does the 3.0V 200mAh CMOS battery draw while the laptop runs all day?
The non-rechargeable lithium cell simply maintains the real-time clock and BIOS settings; it does not power the laptop and therefore draws no measurable current from the system.
What must I already have inside the Dell E6500 for this 30.10 x 20.12 x 4.12 mm battery to fit and connect?
You need the original CMOS battery socket on the motherboard; the replacement uses the same two-pin connector and physical footprint as the Dell 23.22207.041 part.
Will this 0.2 Ah lithium cell work reliably alongside the older original main battery in a Latitude E6500?
Yes, the CMOS battery operates independently of the main battery, so it keeps the clock and CMOS settings alive even when the primary pack is degraded or removed.
