I needed a CMOS clock battery for an old IBM THinkPad 600E laptop that was forgetting time and date. The battery is easy to get at under a bottom cover by removing one screw. I purchased a single CR2025 3V lithium battery and tried soldering the wires (with connector) from the old battery to the new battery, but could not get solder to stick to the metal of the new CR2025 battery (the original wires were spot welded). So I purchased this ready made battery with wires and connector. When starting to plug this new battery into the laptop, I noticed the red and black wires were reversed on the connector. Fortunately I was able to carefully removed the contacts from the connector housing and correct the reversed polarity. (It takes sharp tweezers, a pin and magnifier to do this as the connector is quite small.) After fixing the reversed plus (red wire) and minus (black wire), the battery plugged into the IBM ThinkPad 600E laptop and worked fine. So I suggest that you compare the red and black wires of your old battery to this new battery to make sure it is correct before plugging it into your computer.

The original error from the laptop would not let it boot
I had my doubts that replacing a cmos battery was the
real problem. Imagine my surprize after replacing the
cmos battery and the IBM laptop booted perfectly!
Very Happy!
