Small 43 KB RAR archive for Apple board 820-1819, described as the backup battery charger board. This is a secondary daughterboard, not the main logic board, so expect only a few pages or a compact layout file. Such material helps trace the charging circuit, test the connector pins and check for shorts on a small board that often gets overlooked during repair. Unpack it with WinRAR or 7-Zip and compare the 820 number printed on the PCB before working from it.
