The batteries just do NOT accept or keep a charge. I just recharged the new rechargeable batteries and put them in my Microsoft ARC mouse and they show up at 4% charge remaining! I paid more to buy duracell and they are worthless! I contacted duracell and they did NOTHING! I will NEVER buy a duracell product. (these were made in china) We will not buy things made in china and if there is no alternative we will just go without. Enough of companies selling junk and NOT standing behind their product.
