I guess just heat shrink plastic label is other way round, not the polarity , still funny though.

They're marked for electron current instead of conventional current.

A complementary pair! Are they well matched?

It's a bipolar version of the battery.

It's simply physics! If there's a battery, then there's also an anti-battery. ;)

It's rechargeable, so current reverses. But looks like one battery to discharge, and one that is charge only. Sort of like a write-only memory, (no read :))

There's a Lithium joke in there somewhere. :)

I have about 50 of these EBL batteries (for batch function testing).......I just checked them all and they are ok....:-)

I'm betting it just got flipped around before it went into the machine that applies the label. If the actual polarity is wrong for the terminal gender then that's an issue. In this case I'd just use a permanent marker to cover the markings.

the li-ion is the big inovation here, maybe tesla launched one?
