After using the batteries for the first time, I am very satisfied. The larger capacity is doing very well. I'm curious how long the NiMh battery will last.

With a little teething problems, the batteries I ordered started to work perfectly. One battery was defective, but was immediately and easily replaced with a new one by SUBTEL. When replacing it, it initially looked as if it would not work either, because I had to re-attach it to the SONY charger several times until the charging LED lights up red. Before that, the LED flashed quickly green-red. It is only to be hoped that the batteries will last as long as possible, which I now assume. In any case, the product is at least as good as the original, only much cheaper!
