Cuisinart EvolutionX Cordless Rechargeable Hand Blender

The battery on this unit failed after less than six months. I found out that it is a proprietary lithium battery. I was directed to Batteries Plus to replace it, but they told me that they would have to receive the replacement battery through Cuisinart, and it could take up to two months to get it. Though I purchased this less than six months ago, it had been manufactured three years ago and had been sitting on the shelf all that time. The Batteries Plus expert explained that a lithium battery just sitting around will "eat itself." So the unit was worthless after less than six months. When it worked, it was a good unit, but the battery failure made it worthless. Also it will not operate when plugged in, so I now have a doorstop. Replacement will take up to a month. I am extremely disappointed.
