Lithium 3-volt battery, with solder tabs. This battery must be soldered to a circuit board, and unless you are experienced with a soldering iron, you may not want to tackle this job. If you do, beware that overheating the battery can cause it to explode; make quick solder joints and use a heatsink (instructions are included). Battery replacement is a fairly simple task for a qualified technician; any service center should be able to do the job fairly quickly. Just be sure you save any program data first, as the unit may default to its factory settings when the battery is removed.

Installation of this part requires soldering.
