Duracell vs Energizer 9 volt battery. Are all 9V batteries the same?
No, unfortunately there are very small differences in size of 9 volt batteries, even in brand name 9v batteries such as Energizer (or Energizer Industrial) and Duracell (or Duracell Procell). This plays a significant role in 9v batteries fitting properly into a device. Most people do not realize there may be a difference in 9 volt battery size. It is difficult to tell just by looking at the 9v battery. For example, the Energizer 9 volt battery is approximately 1/16” taller than the Duracell Procell 9 Volt battery.
There are indeed ‘battery standards’ for battery manufacturers to follow. The dimensions for 9 volt batteries are H 48 mm × L 25 mm × W 15 mm (1.9 in × 1 in × 0.6 in). However these standards still allow for varying in size for a 9 volt battery. The maximum size permitted, for example, is 48.5 mm × 26.5 mm × 17.5 mm. The result - electronic devices are not always designed with excess space in the battery cavity, resulting in cavity design that will not accept 9 volt batteries of all manufacturers. Many of the cheaper, no brand name 9 Volt batteries, for example, are too wide for electronic devices. Cheaper batteries are almost always too wide because it allows manufacturers to get away with using less expensive materials.
