Resolution
Schneider Electric no longer sells replacement batteries for the ION 7550 and ION 7650 because the batteries are now soldered to the board. For older versions of the meter, the battery can be replaced with a "Tadiran Model: TL-5276/W or equivalent". Please follow the attached document for battery replacement instructions.
