Reversal Protection
Reversal Protection

• When a battery without reversal protection is installed in reverse in a device (e.g. boom box) with 3 or more other batteries and the device is turned on, the device will likely still run (e.g. play music). 

• While the device is running, the incorrectly-installed battery will be charged by the remaining batteries.

• Alkaline batteries are not designed to be charged and could potentially vent under these conditions to minimize internal pressures.  When a battery vents, there is a strong possibility for leakage.


1. Include plastic ribs in device battery compartment to prevent incorrect
installation and electrical contact.

2. Energizer Max C and D size alkaline products have a non conductive coated ring on the negative contact. The coating
can be seen under a UV light.
