The battery is a proprietary design with both positive and negative being at the same end,

But why do they still put the (+) marking on one end and (-) on the opposite end? This is confusing.

It is a protected battery, with the same polarity contacts as a normal battery. But, it also has an exposed negative contact area around the positive button contact, isolated by a plastic collar ring, to allow single end charging. Typically this area is covered by the wrapper and a flat paper ring to hide the negative portion by the positive button.

I see. Thanks.
