I have only come across lithium batteries from Apple. I've never used alkaline batteries in my mouse. Instead once the original lithium batteries are worn out, I use rechargable batteries. I'm currently using 2000mAh Ni-Mh, which seem to last at most a couple of weeks before the first warning comes on, then for a month or so. This means that it sits on the warning for significantly more time than without claiming I need to change them. Maybe the problem is that rechargeable batteries run on 1.2 volts instead of 1.5 volts.
