One Battery Comes Out On Top After Comparison Test

Most of our battery powered devices use a major brand of rechargeable batteries, but there are certain devices that still require regular batteries (like our wireless alarm keypad, which drains rechargeables too quickly). But which battery provide the most bang for the buck? Based on the scientific research at Worcester Polytechnic Institute, you might be better off buying any of those cheaper priced batteries because there is no measurable difference in quality for premium brand batteries versus generics (99 Cents Only Store time!). Except for one battery, which outlasted the rest 4-1...

After 19 hours, the Energizer Advanced Lithium battery was still running at 1.5 volts — far higher than any of the other batteries. The WPI team said that it showed "remarkable stability" compared with the rest. The testers said there was no statistically significant difference between the other batteries.
