If you re-read my posts, you'll see I never claimed otherwise. What I did say was that if the battery fails with a battery from a brand-name, you have a warranty to fall back on (and a pretty good chance of getting your camera itself replaced, if it's damaged by a battery failure).
Originally posted by creampuff I have had an original Sony Vaio laptop battery fail within a month of purchase. If not for the warranty, I would have been US$300 poorer. My Macbook had a battery recall, and the batteries were made by Sony.
Which rather proves my point. With no-name third party batteries, you'd have had no recourse -- either for the battery itself, or for the product it was used with. For a name-brand battery, you have a warranty and recourse.
Originally posted by creampuff My wife's original Blackberry battery also failed within 6 months. The 3rd party battery bundled free with it at the time of purchase still works fine.
And it could just as easily have gone the other way around. I'm not familiar with Blackberry's warranty terms, but chances are you were still covered again in that instance. The chances of you having been covered by a warranty with a no-name battery are about zip.
Originally posted by creampuff The 3500 mAh rating allows me to shoot a little over 1000 shots per charge. Again no issues.
3500mAh printed on a battery that's supposedly identical in design to an original battery that's 1860mAh makes me raise my eyebrow, to say the least. Third parties can't magically fit more powerful cells in the same housing than the original manufacturer can, and we've not had any advancements since the K-7 shipped to nearly double lithium ion charge density.
That's another of the problems with no-name third parties that I've already mentioned in this thread. They can print absolutely anything they like on the label, true or not. I'd wager that battery pack contains nowhere near 3500mAh. Honestly, I'd be surprised if it provides much more than the Pentax version, if any at all. With a name-brand battery, you at least have a reasonable expectation that the battery will provide somewhere near what's printed on the label. With the no-name third party battery, that's often not the case, and a battery that's claimed to offer the same as or more than the original battery can turn out to offer far less charge capacity.
And I'll say it once again, by "name brand", I don't mean the same brand as the product it's used in -- I just mean a reputable company with a brand name somebody's heard of, a warranty, and a clear way for the customer to contact them. That includes the original manufacturer (Pentax or whomever), big names like Eveready etc., and lesser known names like Maha, etc. Thing is, I'm not aware of any big names other than Pentax themselves offering the D-LI90 yet. Our choices are basically Pentax, or the no-names. Hopefully that'll change, and thankfully Pentax hasn't taken the route of some manufacturers in making it so that *only* their batteries will physically work.
