This is a new high quality Lithium ion polymer battery for the Palm Z22.  The battery has a one year warranty and requires it to be soldered directly to the motherboard - the solder pads are fairly large and do require a good soldering iron to complete the task.  If you prefer not to install the battery yourself please see our Palm Z22 Repair Service.   A case opening tool kit is provided as an option below.

Rating 3.7 VDC, 750 mAh
