TIP: The negative (-) side of a the battery goes on the spring side of the device and the positive (+) side of the battery goes on the flat side of the device. If the device has no spring, look for the + and – imprints on the device and the battery to correctly replace the battery or batteries.
All batteries have a + or – sign on each end. Batteries have two terminals: positive (+) and negative (-). This tells you which end of the battery is either positive or negative. Look at the ends of an AA battery, it will show a positive (+) on one end and a negative (-) on the other. The flat end is the negative – side and the part with the nub is the positive + side. See images below…

On most battery operated devices that use round cylindrical type batteries such as double AA, triple AAA, C, and D batteries, the negative end (flat end) of the battery goes on the spring and the positive end (side with a nub) goes to the positive end. The spring is there on the negative side to apply pressure on the battery to keep it in place so that it stays secure.

Note that some toys or other battery operated devices may have the batteries installed in a different manner then described. So always check to see if the toy or device has an illustration on the back cover of the battery compartment. If there is no illustration, look for a plus sign where the batteries go in the device and most will show a positive (+) or negative (-) as to which way the batteries need to be installed.
Does the negative side of a battery always go on the spring?
On most battery operated devices, yes. The spring is the negative end for the AA or AAA battery to connect to. The spring keeps the battery in place.
