Also, I can unfortunately only awarded one star. The reason I have already mentioned in the heading. In Abus smoke detectors RM 04 Li batteries are not working. The description here "The powerful batteries are particularly suitable for devices that have a high energy consumption or are frequently in use." So not true and I feel as fraudulent advertising promises! Smoke detectors have a continuous low power consumption, so it would certainly fold here. Unfortunately, I have bought this, these two batteries and a charger specially a few weeks ago and left me blindly.
I'll try, but therefore do not think I can return batteries and charger. This makes the whole thing for me then even more annoying, because I only need for smoke detectors in my house yet 9V batteries ...
And seriously: if it is not enough for smoke, what it is to be rich? However, I am not a technician or electrician, maybe there are some which physical relationships which mean that those batteries are only effective in high energy consumers, but not in low energy consumers?
