Some CMOS batteries may be held down by a metal clip or bar. The battery can be removed by sliding it out from under the clip. Do not bend this clip to get the battery out, as a bent clip can result in the new battery not staying in the socket. If you cannot locate the CMOS battery, refer to the motherboard documentation or contact the computer manufacturer. If you no longer have the documentation for the motherboard, it's likely you can find it online. With some computers, you may need to disconnect cables, remove drives, or remove other parts of the computer to get full access to the CMOS battery.

Unfortunately, most manufacturers do not list the exact type and model of the CMOS battery. Once you have located the battery, we recommend you write down its specifications voltage, chemistry, wiring.

If possible, remove the battery and take it to a retail location. If your computer uses a coin cell battery, removing the battery is relatively simple. Use your fingers to grab the edge of the battery and pull it up and out of the socket holding it in place. Some motherboards have a clip holding the battery down.

If your computer's motherboard has this clip, you may need to use one hand to move the clip up and the other hand to pull the battery out.
