I'm assuming there is no such thing as Quality Control when testing batteries, is there? Heck, I think it's also a safe assumption that testing batteries doesn't exist, right? After all, if you test a battery to see how long it's going to live, then you've effectively killed it and cannot sell it. Or so I would think.
In my quest for the perfect battery to power up all my varied electronic devices, I decided to take the Rayovac Power Challenge.
I'm a lifelong user of Duracell and Energizer batteries because those names have always implied durability and long life. So if Rayovac, a brand I've come to mentally associate with "one step above generic," is going to make such a bold claim and offer up wonderfully colorful and highly scientific charts such as the one at right, why not give it a go?
Oh yeah, the price point was pretty good, too. I got 24 batteries for the price of 12 Duracells.
Perhaps that should've been the first sign.
I don't care what they say, but the Rayovacs I've used so far in my digital camera have been for crap. I put two of them in my Sony DSC-P92 last Thursday and, by Friday, they were failing to open the shutter. They kept reading that they were dead. And this was my first shoot using them. That can be more than a bit annoying.
But to rub salt on the open wound, they showed full battery life when I put my camera on viewer mode to offload the pictures to my computer. What the???
So I flipped it back to camera mode and, just like magic, they were dead again.
On Saturday, I put in a new deuce of Rayovacs since I still had so many left, and, so far, they're working fine. But I haven't turned the camera on today at all. Wouldn't surprise me if they, too, died.
And I still have yet to mention the fact that a pair of them lasted a meager week in my bluetooth mouse. Most batteries last a minimum of a month. If you go for those E-squared batteries, those tend to last for three to four months. But those cost an arm and a leg.
I'm getting frustrated here. I don't know what to buy.
Is there such a thing as a "good" battery in this day and age?
I want to find the creator of this challenge and pelt him with dead Double As. Can you imagine the headlines? "Rayovac founder mortally assaulted by dead batteries." That would make this worthwhile.
