Originally posted by Rondec I have bought Watson and Wasabi batteries in the past and both style flaked out pretty quickly. A year or two of use and they stopped holding a charge as well and the off brands did quite poorly in cold weather. Obviously my sample size is pretty small, but I won't buy the off brand batteries any more. They just don't seem to last long enough to make it worthwhile.
We should measure time by number of charges, not number of weeks. By that measure, both my “Wasabi” and my “Kastar”
batteries have lasted about 100 by now, exactly the same as my two “Pentax” - the “Wasabi” wouldn’t charge last “80%” on my “Watson” charger, but it cost less than 50% of what a “Pentax” would, and the “”Kastar” cost even less.
I also use the same brands in my Q-7 - where all last the same ...... which Pentax ‘abandoned’ long before I did, so I certainly feel no “guilt” there.
But this thread is supposed to be about the K-3iii.
