Some sites, listed in post #5, including HRO. have the same small battery picture.
It does not means one way or the other, I think it makes the scanner looks neat so they stick with it. But I also aware some good reputation sites (based on this site's consesus) use the old picture and then phrase it by saying "now ship with extra large battery" to make it sound as if it is an extra bonus from retailer.
The 3rd party sellers on Amazon frequently jack up price when Amazon is not selling a product or is out of stock, the 3rd party seller may fall back to match Amazon or few cents below when Amazon is back in stock with regular or lower price. This is 3rd party seller's problem .
Make no mistake I'm not here to endorse Amazon, indeed I am not a prime member.
