    • Disconnect the connector circled in red.

    • Remove the battery.

    When sourcing a replacement battery note which connector pin has the red wire. This is shown most clearly in the middle photo for step 12. Be careful, as similar batteries have the reverse polarity.

    I bought a ten-pack of batteries for less than some suppliers were selling a single battery. EEMB CR2032-Molex51021-RP (CR2032-MX51021-RP). The connecting wires were longer than the original, but were easy to fit into the battery space.

    Very many thanks for this great guide - it saved me a lot of unnecessary work.
