    • Most laptops use a CR2032 or 2025 cell. The CR2016 cell is uncommon.

    • Take the battery apart and check out what cell you need. This may be difficult depending on the wrap used.

    • If you break the leads, a new battery will need to be purchased.

    • After purchasing a battery, disassemble the CMOS battery. Use caution not to heavily bend the tabs. Too much damage may make them unusable.

    • Break the tabs off of the old battery. Dispose of based on your local laws.

    • ONLY USE ENOUGH TAPE FOR A FIRM HOLD. Using too much may short out the cell! In addition to using as little tape as possible, the cell must be tested before installation with a multimeter!

    • After the polarity has been matched, tape the positive lead to the new cell. To remove the risk of a failed rebuild, start on the + side and cut the tape to fit comfortably.

    • To place tape on the negative tab safely, try and keep the tape you cut as close as possible to the example image.

    • OFFSET the tape and terminal placement from the positive tab as much as possible.

    • After confirming the tape is not causing a short, add tape to the negative tab and tape down the negative terminal onto the new battery.

    • Perfect coverage is not required. Focus on covering the major parts of the battery.

    • After verifying both leads are securely held onto the new cell, apply liquid electrical tape to the battery. 2-3 medium thickness coats are recommended.

결론

After building the replacement cell, install it in the notebook. Verify the battery works by setting the BIOS, powering it off and then removing the battery/AC adapter. If the CMOS memory is retained, your battery works.
