We use batteries for our electronic devices and even toys. If there are kids in the house, there may be a lot of toys using batteries like the duracell procell aa. If not toys, we use the batteries for our remote controls for use with our TVs, recorders and even airconditioners. Some companies have their own stock of batteries also for use with their remote controls that may be used for their projectors, airconditioners and players. Having some batteries in stock assures us of continual use of these devices. We wouldn’t want to find ourselves trying to find batteries when an important presentation is to be made.
