Should You Buy Generic or Brand-name Batteries For Your Gadgets?

Have you ever stood at the store, looked at the rack of batteries, and tried to decide whether you should fork over extra cash for the brand-name batteries? If you have pondered this, one site purports to have the answer: buy the cheapest batteries that you can, as they all perform similarly (with one exception).

Worcester Polytechnic Institute, at the request of DealNews, performed a test of different AA batteries to determine whether there’s any real difference between generic and brand-name batteries. A professor and a group of students conducted the test over several months, buying the batteries at retail.

The Institute determined that there was no measurable difference in quality among the batteries, with one exception. The Energizer Advanced Lithium battery outlasted the others. The problem is that the Energizer Advanced Lithium battery costs about four times as much as the cheapest battery.

One MAJOR caveat with this study: the people who conducted the study warned that the testing only included the pressures of constant demand, and not everyday usage, where our devices are constantly turned off and on.
