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.
