Product Details: This 1.5 V battery is a replacement for the batteries SUM/UM 1, 2, 3, 4 and SUM-5. It is the wider of the two N batteries (11/32″ wide) and has a tiny “nipple” on the end. When replacing your N battery, make sure this is the correct one as the wrong N battery will not fit in the battery case.
