Alkaline batteries are the basic power source for numerous devices, but battery power does not last forever. When you have to change alkaline batteries, the batteries can, over time, become stuck in the devices they service. If you need to remove a stuck alkaline battery, the key is to pop the battery back into alignment against its spring.
Open the battery compartment of the device from which you want to remove a stuck alkaline battery.
Wedge a butter knife between the stuck alkaline battery and the side of the device.
Press left or right with the knife while also pushing downward a bit to cause the battery to align against the spring and spring forth from the device.
