Watch Battery Cross Reference
Every battery manufacturer is at complete liberty to use their own convention or naming system for batteries. There are a few standard systems, such as by the I.E.C., but these aren't universally adopted. Minor variations in battery specification lead to additional confusion because the same battery can go by a number of different designations, and one designation can refer to different incompatible batteries.
To identify the correct battery, the best method is to rely on more than one designation, and to verify battery dimensions. The table below should be of help in getting the battery codes right.
