  • \$\begingroup\$ The specifications printed on the drill are of the battery pack - note for example that the units are Ampere Hours not Amperes. They do not indicate how to charge it. It's unclear if the charge controller must be external, or if DC power should be applied to an internal charge controller. Without knowing this, there is nothing you can safely do other than cease using it or obtain a matching charger or charging power supply from Ikea. This is an off topic question about the usage of consumer electronics, not an on-topic question about their design supported by necessary details. \$\endgroup\$ – Chris Stratton Nov 15 '18 at 18:29

The risks are fire and explosion, and these are pretty likely to occur if you connect a 12V charger to a 7.2V LiIon battery.

Use a charger that is designed specifically for the battery you have.

  • \$\begingroup\$ OP doesn't even have a charger, just a 12v power supply which will just pour current into the battery until it catches fire. \$\endgroup\$ – John U Nov 15 '18 at 15:03
  • \$\begingroup\$ Just to be abundantly clear, what Elliot is saying here is DO NOT DO THIS. \$\endgroup\$ – Hearth Nov 16 '18 at 1:40
