As with any new battery, you should charge it and drain it 3 times to "wake it up" upon receipt. This, and keeping it in a charged state, will prevent premature failure.
Now to tell if you bought a genuine product - the packaging is very distinct - clear plastic box folded from thin sheet plastic and meant to be hung on a rack. The box is much larger than the battery, and includes a small instruction card. Finally, both the box and battery carry the VholdR logo. Any other cheap packaging indicates a cheap battery. I bought mine from amazon and got the real thing which works fine with their system.
Technical specs: 1050 mAH Li-Ion, with 3 terminal sensor for charging properly.
Finally I don't want to stereotype that all non-OEM accessories are sub-par but as far as batteries go for cellphones, I have a motorola that will run 4-5 days while so called "super-aftermarket" batteries can barely keep it alive 30 hours without any use. Given these are the same size batteries I'd expect the real product to be essential here. I have designed products with Li-Ion batteries and met with the companies in China who make them - they are not ashamed to inform you that statistically one in 100,000 cells will fail explosively. That's 10 parts per million fail rate. But put 10 cells in a laptop and now it's a 100 part per million fail rate on laptop batteries since they have so many cells. So far this li-ion problem has only been improved, not eliminated, so stick with products designed for your system. As for other batteries, my GM car has an interstate battery that I replaced, and my honda has the factory battery which lasted 6 years.
Enough of that. I was nervous about the battery I was going to receive based on the reviews. With my experience with Amazon being great I decided to order it. It turns our that the battery is the real deal, genuine Contour in a seal container with an SKU # 2350 that is a 3.7V and rated 1050mAh, which is identical to the one provided with my camera. Since I just opened it up and it's currently on the charger I cannot testify to the quality/duration of the battery.
That being said, I want to let you know that I'm a nutcase when it comes to batteries. I have over a decade of research into batteries, including talking directly to three major manufacturers (Duracell, Eveready & Rayovac) in regards to the truth behind each chemical make up and their pros and cons. In the early 90's I wrote a 3 page guide on battery use and care. One piece of advice I will pass along is that the battery life ratings are always deduced when tested under optimal conditions. In other words, 1) a fresh battery, 2) properly charged, 3) ideal conditions when loaded (being tested), 4) usually minimal drain is applied (in the days of VCRs this meant no; RW/FF; Stop; Start; Eject; Pause, etc. just straight "Record" in ~70 degrees F.) What this comes down to is do not expect the full 3 hours that the battery is rated at in the real world. This is due to multiple factors such as after the first 1/2 year your battery is no longer "new". You most likely will be using your device hours or even days after charging and batteries, which by their nature lose a fraction of their charge every day.Read more ›
