I ordered these batteries 3 months ago, now-2 battery has leaked, and have ruined me two units, including a Magic Mouse from Apple, which is not cheap. Therefore I can only recommend: Stay away! That can not be a genuine batteries, they are not delivered in original packaging ... Here is something rotten and Amazon should investigate the! Apparently other buyers have had the same experience, unfortunately, I did not read before buying. Now I have two broken equipment, which cost me about together 100.- damage ....
