Rayovac electronic batteries provide high performance at a great price, keeping your specialty devices going strong. For use in devices such as watches, calculators, remote controls and medical devices. There are multiple types of testing before a Rayovac battery reaches the time to be packaged. The three strong areas that are crucial for passing are : The capacity test to see how long it lasts; An accelerated test to see how long the battery can hold up to extreme temperatures ; An electronic test to see if the battery is working correctly ; If you can replace your own watch battery then you can make a huge saving. Jewellers and Watch Centres usually charge a flat rate for watch battery replacements. This means if you have a simple removable back you are subsidising the cost of more difficult and/or more expensive watches.
