Comments:
This small battery is commonly used in many IBM THINKPAD SERIES laptop computers. Our battery is a geniune replacement for the CMOS battery mentioned. This battery can be used in many IBM ThinkPad T20 Series, IBM ThinkPad T21 Series, IBM ThinkPad T22, Series IBM ThinkPad T23 Series, IBM ThinkPad T30 Series etc laptop computers which use a 3.0 Volt clock battery. See here for a fuller list........

Our Panasonic CR2032-WR replacement CMOS battery comprises:

Panasonic CR2032 lithium cell.
a 2 pin connector.
3.8 cm cable.
shrink wrap marked "Type, Panasonic CR2032, LITHIUM BATTERY, IBM P/N 02K6572, FRU P/N 02K6541".

CMOS & Clock Backup batteries perform an important function when the power is turned off; the CMOS battery maintains the time and date, thus insuring their accuracy when the system is once again restarted. Also important, the battery saves the computers BIOS set-up configuration, so the system can be efficiently rebooted once it is switched on again. For example, the computer knows what type of hard drive it is booting from etc. These batteries are variously known as CMOS batteries, Real Time Clock (RTC) batteries, PRAM batteries or simply internal batteries.

In most cases, replacement of the CMOS battery is an easy task. It is simply a matter of locating the battery on the computer's motherboard, removing it and plugging in a new one.

This CR2032-WR should not be confused with the CR2032-3P (P/N 02K7063) which has a 3 pin connector and is compatible with many other IBM Thinkpad laptop computers such as the IBM Thinkpad R32 series and the IBM Thinkpad R30 series. For other CMOS RTC Batteries look here........
