Magic Mouse Batteries
Fact: The Duracell Batteries in my Apple Mouse last 28 days business days.
I put in new batteries on November 20, 2015, so that means I should plan on the needing to put new batteries in around the 4th of January. This is taking into account various holidays and upcoming PTO time.
A few weeks ago Apple announced the Magic Mouse 2, which is the next generation of their wireless mouse. The really cool thing is that you no longer need to buy batteries as the mouse can now be recharged via the lightning port. The downside is that this new mouse cost $79. I don't know if it's really worth that much to install batteries every once in a while.
Amazon Basic has 16 AA rechargeable batteries for $26.69, and that will last for a couple of years. Seems like a much better investment than getting a new mouse. I am thinking that they might even be cheaper over the next month or so.
