Most do, several have replacement battery packs (using standard batteries rather than the original (and now inoperable) rechargeables). I think only two on those bars didn't have batteries when I photographed it. Now one of my miNewt's battery has died. I'm thinking it's getting close to the time I pick up a NR Lumina 650.

As to Duracell?... Lemme Say this: Thank Goodness for DollarTree.
