    I'm just curious about the accuracy of the Battery Level indicator. My mouse batteries are at 5% and I'm wondering if they will last a few more days or if I should replace them now.

    They will last 5% more, how long that takes depends on your usage. Should you replace them now....well that's up to you.

    Replace them now. Even though they will probably last a bit longer, you don't want to be in the middle of something when they die. Best to just get it out of the way so you don't have to worry.

    Agreed, batteries are cheap, no need to drain every last watt out of them. If you are down to 5% I would just say replace them - it's not as though the battery indicator is overly generous i.e. you could actually keep using the device for months. It would suck for the batteries to go while you're in the middle of something important, so I'd say just get 'er done and swap in a nice new set.

    Have a new set ready so that you can swap them the moment the current batteries are empty.

    The battery indicator level also depends on the type of battery. With rechargeable batteries for example, my experience is that when they drop below 15-20% they will only last for a short time. T

    If your batteries are rechargeable, it is better not to drain all of their power, because the battery life will be reduced and you will must buy new batteries. When my batteries are between 10 - 15 % i change them with new fully recharged.

    You will need to replace them when it reaches 0%.

    I find I need to replace my batteries once they dip below 10%, else the trackpad will just switch off by itself and not my my comp detect. :p
