What the pack contains

This pack supplies five CR2032 coin cells each fitted with a two-wire connector for direct attachment to a laptop motherboard. The cells are new and intended for technicians or owners who maintain several machines and want a ready stock of replacements.

Sustained behaviour

Each cell is rated to maintain the real-time clock and CMOS settings for up to eight years under normal standby current draw. The chemistry delivers a stable voltage throughout that period so the system clock does not drift and BIOS configuration is preserved without frequent swaps.

Installation notes

Replacement requires only opening the chassis, unplugging the old connector and pressing the new one into the same header; no soldering or special tools are needed. The main risk is inserting the plug with reversed polarity or forcing it into a keyed socket that uses a different pin pitch, which can damage the motherboard.

Questions about this item

Does the CR2032 cell generate any heat or noise while the laptop runs all day?

The CR2032 CMOS battery is a passive coin cell; it produces no heat and makes no noise during continuous laptop operation.

What connector must the motherboard already have for this 2-wire battery to plug in?

The motherboard needs a 2-pin JST-style header that matches the battery's 2-wire plug.

Will this 2-wire CR2032 work in an older ThinkPad T430 that originally used a different CMOS battery?

The listed compatibility starts at T440P and T440S; the T430 is not included, so fitment is not confirmed for that model.
