BP-22i : 8.4 volt 350mAh NiCd replacement insert - goes inside ICOM BP-22

The BP-22i insert is an 8.4 volt 350mAh assembly that goes inside the ICOM BP-22 battery pack (for the old Micro 2 series).  These inserts are now made with premium-quality SANYO 350mAh NiCd cells.  Some disassembly, re-assembly & soldering is required.  The original BP-22 battery pack unscrews open, which makes installation of this insert fairly easy.  Some soldering is required.
