, , , and thus are already two major called (with key) characteristics of the battery: The first charge I have nearly 300 photos taken, most of them with lightning. Perfect fit he is twofold. He slides easily into the battery compartment of Konica and can be just as easily removed again. Nothing hooked or jammed. As easily it fits into the original charger Konica and in a no-name charger that I bought years ago on Amazon.
What I can not judge, is how many charge cycles of the replacement battery by holding, without noticeably losing power. If the relatively happen, I'll make an addendum to this review. So far I can only say that I am very pleased it buying.
