It is always best when implementing alkaline batteries testing of your own battery brand, always utilize the ANSI standard tests for consist ant relevant product results. It is always recommended that you utilize a highly qualified battery testing house. Rayovac will recommend or utilize the Rayovac standard battery testing facility upon request.

Device product testing is highly inaccurate if not done correctly and very very expensive to do correctly. The most common real life alkaline battery flashlight test is a continuous drain test that doesn't always properly demonstrate consumer usage. Most batteries are usually not manufactured to perform this way for this particular reason.

FAQ 

1. Who determines the American National Standards Institute (ANSI) alkaline battery test standard.

Standard ANSI Battery performance standards are set by of five official committees with major participation from battery manufacturers, product user groups, and battery interested organizations. The constant participation of these different groups ensures that the tests created are always accurate and dependable for consumers of batteries.

2.       What are the ANSI alkaline battery test application tests?

Product battery tests are intended to simulate commonly used consumer for battery powered product devices to always ensure high consumer satisfaction. Both AA and AAA alkaline batteries tests are used in with many product devices ( such as flashlights, radios, cameras) and therefore have many more common resistance drain tests than C, D, and 9V size batteries.  The product service tests are mainly to provide a basis to evenly compare batteries and test different battery types, sizes and brands on common tests that are highly relevant to products used by consumers. They also assist battery operated product manufacturers and designers on how batteries are internally designed. All these alkaline battery tests are regularly updated to ad hear to ANSI standards. This includes D size, C size, AA size, AAA size and 9volt batteries.

3. What is the best way to test alkaline batteries?

Valid results are best obtained from a recognized battery test provider or laboratory. We can recommend several test houses. Experienced test labs will perform the ANSI tests as specified, providing independent, indisputable data for marketing and product improvement confirmation. This can be expensive and take a long time. Full ANSI regime can cost thousands of dollars and take 12 weeks to complete all sizes. This includes D size C size AA size AAA size and 9volt batteries.

4. Can Rayovac test batteries?

Yes, with our Rayovac extensively battery testing lab expertise, Rayovac can accurately perform ANSI tests, including competitor testing and detailed reporting. The major battery tests are conducted and then reported by some of the best computerized battery test equipment available. Currently, Rayovac has conducted over 16,000 battery test with little room for any error. Rayovac’s battery test results mostly agree well with the major oust side independent recognized professional battery testing laboratories.

Yes there are , but they are not as accurate and produce highly irregular results. If you choose to do your own testing at home, they must be controlled by running several different devices and many many test repetitions in order to make positive statistical battery comparisons. This can be very time consuming and expensive. These tests should also be done with intermittent use cycles to be valid such as turning the device on for one hour per day, like the ANSI tests. Without sufficient testing, the data is usually misleading.

We recommend that you always use target devices such as toys, cameras, and flashlights and use multiple devices of the same model (at least 3). Battery powered products can vary as much as 25% among devices of the same make and model, more than the common variance among battery brands.  A key issue with testing batteries in this fashion, is that across different brands and models of devices. This type of testing also requires several repetitions of tests of each battery brand in each battery operated device.

Best option to test batteries: ANSI testing done by recognized test providers.

6. What are the continuous use alkaline battery test ?

The continuous use alkaline battery test ( continuous drain test or constant battery burn test) is when you switch on a device and leave it on to compete exhaustion. Batteries should never be tested in devices under continuous power drain. This is not a way that a majority of consumers use batteries. As recognized in all of the regulated ANSI tests, the battery power is drained intermittently, such as 1 1/2 hour per day, to more accurately reflect the way people use the product. Most alkaline batteries are not designed for continuous high power drain use, such as a high wattage LED light. Most batteries are formulated for pulsed power and many daily use periods which is most consistent with regular consumer usage. So, product device testing should always include intermittent drain test schedules in cycles.
