magic mouse disconnecting

Do you have more than ONE bluetooth item going at once? If you turn your mouse over, does the green light stay constant. Is there a forum site for Macs on Twitter to check out if others have a similar problem. I don't use it?

Which browser are you using and what version?

Just to clarify the reason for the fix, what brand of batteries are you using?

In order to be sure you have solved your problem, buy a pair of 2400 Duracell batteries. They are probably the best for your mouse. Until you put the right batteries in, you cannot really help yourself. Please do this.

Battery sizes are not consistent from one brand to another. The difference may be slight but the effect is one of unreliable performance and frequent disconnections. You can often test by shaking the mouse to see if it rattles.

I cannot say yea or nay to any particular battery but within these forums the following batteries appear to be the most reliable. Duracell, Energiser and Eneloop. Apple batteries used to be in this group but my experience of them of late has not been good.

Then you have to consider regular batteries and rechargeable. Regular give between 25 and 35 days usage. Rechargeable (after the first few charges) tend to last between 12 and 18 days ... and quickly deteriorate from then onwards.

I found that cleaning all four battery contacts in the mouse worked great for me. There are many ways you can clean them. What I did was take a small piece of sand paper and use the tip of a small screw driver to rub the sand paper all around the surface of the "+" terminal side. I then used my finger with the sand paper to rub it around the "-" terminal side. Working great for me now.

Another method to clean the contacts is to use rubbing alcohol with a cue tip and rub hard on the contacts.

Here's another possible fix: leave the cover plate off.

I was having frequent disconnects, tried other solutions including the bit of paper, but when I simply did not replace the bottom cover of the battery compartment, it just worked without disconnecting. I suspect my rechargeable batteries have the sizing problem mentioned above, although I had used them for at least a year before the problem started. If you do this, I suggest also being diligent about cleaning the terminals each time you replace batteries.
