Re: 2465B battery

The battery is part of a Dallas chip part number DS1225Y and this is a non volatile SRAM chip.

It’s a 28 pin dip part that is soldered into the board. To replace you need to unsolder the part, use a suitable programmer to read out the contents and copy the data into the new part. It’s also a good idea to add a socket to the board for future replacements.
