Since my household is often necessary to use a flashlight, you occasionally have to buy batteries. This time the choice fell on the batteries energizer. Since the headband lights usually eat AAA batteries, I just bought this battery in this format, and not trying to get a flashlight to move to other types 
As we know from advertising, Energizer batteries last a long time, longer than usual, then why the desire to try them. Well, in general the result is quite normal. Lantern quite a long time, although the exact timing I was not spotted. However, the world, they obviously longer than ordinary batteries. I do not know how other batteries, no pacing, but these initial stress was 1,56-1,57 V, which prompted the idea that due to increased stress and can achieve a more prolonged use of a battery. Unfortunately, the manufacturer has no website in Russian, so all information can be found on the European site .
