Hello Guys,

Please help me how to properly remove this CMOS battery as sample attached picture.

I removed others with easy clip while this one seems quite hard to remove.

Thank You.Its a standard coin cell. These are held in by the white PLASTIC holder. You have to carefully apply pressure to coin cell opposite of the side you will apply outer pressure to the white plastic to allow for the coin cell to tip up in the corner that the white plastic is pushed carefully out away from coin cell.

If you apply too much pressure you can break the plastic holder and be in trouble though so only apply the bare MINIMUM pressure to get the coin cell top pop up out of the holder.

Putting replacement battery back in you need to put the new coin cell (probably a 2032) battery in the same POLARITY orientation. I use a toothpick to press the tension clip.Good Eye Patio...    in picture I didn't see that.

There are some battery holders out there that the plastic acts like jaws that hold the coin cell center to itself. Looked back after you MENTIONED toothpick to the tension clip and now I see it on the right. Thanks for the replies guys.

Tho I tried to be extra careful not to break the plastic jaws, I did break the other small 2 claws and left the center claw and the other 3 claws from other side intact.
