Mine looks pretty much the same, still about half charged after almost two days of use.. Thanks for posting. FYI the link i left for the battery, a little cheaper and it's 300ma instead of 260 i think yours has. Better deal, but then again it's probably a little smaller so easier to get in..
I personally don't care so much about the mAh; I'm more particular over having a working battery, haha. My old PD3032 only ran battery for ~20 minutes and when the watch drew high amounts of power, it didn't last a minute.
The extra ~80mAh are only a benefit, plus the new battery was cheaper.
I like it, thanks for posting.. My old battery lasted mabye 5 minutes.. Now it's three days later on a single charge..
For the record, if anyone needs the info, i did get the case on. It's a tight fit, but works fine, make sure you insulate the exposed battery contacts from the case, i used two layers of electrical tape. If you short it out, you should be able to revive it by plugging in a powered usb cable, a soft reset might do it too.
