Gemrod - Got my calipers back in January. While I MIGHT need one spare battery before they all go bad, there's no way I'll use both. The one I keep at home will have the battery replaced on my dime. The one I keep at work will have the battery replaced by my employer. We keep batteries on hand for this, so it's no big deal.
Soooo........as I see it, unless you want me to just waste a battery, you need to PM me with your name/address so I can send it out Monday morning. You'll just be doing your part to save the local landfill here.;)
There's absolutely NO WAY you're going to pay me for this. I'll wrap the battery (still sealed in its wrapper, BTW) in a copy of the instructions. Mine is the 6" caliper, model#47257.
