I glued some magnets onto my power drill battery to use for storing drill bits on - but will the magnets affect the battery life?

For one, the magnetic field generated by the magnets are going to be small potatoes compared to the magnetic fields generated by the motor while in use. Two, battery chemistry is essentially unaffected by ferromagnetic fields of the magnitudes you'll encounter in everyday life. Thirdly, there exist specialty tools that have a big magnet on them out of the factory, designed for drilling holes in large pieces of sheet metal, and those of course have no problems.

Unless the magnet is strong enough to lift several 747s off the ground, it's not going to have any impact on your battery.

An 18V (Ni-Cd) drill I personally own has a rather strong magnet mounted directly over the battery. I rather doubt they're do that unless they were reasonably sure the magnet wouldn't cause battery problems.

Doubt it. I've carried several magnets right on top of my blackberry and all is well. I consider the drill heavier duty than a blackberry so I think the drill will be fine.

Do you have any data to support your claim? Are you sure the OP's drill battery is the same type as your BlackBerry, or whether or not there is any type of shielding in either device? –  Tester101 Dec 23 '12 at 13:46
    
The only part of a modern drill battery likely to be attracted to a magnet is a steel casing. The chemistry inside doesn't care about weak magnetic fields. –  Wayfaring Stranger Dec 23 '12 at 14:47
