CMOS Battery for Legacy ThinkPads

This replacement CMOS battery supplies the 0.2 Ah lithium cell needed to keep system time and BIOS settings alive on a long list of older ThinkPad models. It fits machines ranging from the 560X and 570 series through the A, R and T lines up to the R500 and T510. The part also covers several Medion, Gateway and Evesham notebooks that share the same coin-cell footprint. It is a direct swap for the original 02K6541, 02K6572, 02K7078 and 92P0986 batteries.

Installation Requirements

The cell slots into the existing motherboard holder and connects via the original two-pin lead, so no soldering or adapter cables are required. A small Phillips screwdriver is usually the only tool needed to reach the battery compartment on the supported laptops. Replacing the coin cell restores reliable boot-up without losing date, time or hardware configuration between sessions. The green-wrapped package matches the OEM form factor and ships ready to install.

Capacity and Service Life

The 0.2 Ah lithium chemistry provides enough reserve for years of standby time on the listed platforms. It comfortably maintains CMOS data during extended periods when the main battery is removed or the notebook is unplugged. The cell will eventually deplete after several years of continuous use, at which point the system will again lose its settings on power loss. Buyers needing a higher-capacity main battery or a rechargeable CMOS alternative will not find those functions in this single-use coin cell.

Questions about this item

How long will the 0.2 Ah capacity keep the CMOS settings alive when the laptop is off?

The 0.2 Ah lithium cell is sized to maintain the real-time clock and BIOS settings for years while the main battery is removed or depleted.

Does the battery generate any heat or noise during continuous operation?

A CMOS cell draws only microamps, so it produces no audible noise and no measurable heat inside the chassis.

Which connector or cable must already be present on the motherboard for this DS-CS-IBR500BU to fit?

The replacement uses the same two-pin JST-style header found on ThinkPad 560X, 570, R50, T20, T40, T41, T42, T43 and compatible Medion or Gateway models.
