I run 2 of 4 sets of batteries in accordance with high quality LED lamps from NiteCore and NITEYE. Even with the built-loaders of these devices, these batteries are properly charged - I measured it with an Xtra VP1. The batteries are also just long enough to reliably make contact in a TM 26. However, these batteries do not fit into older Fenix lights with a narrow housing (Tk 12, Tk 30). Even the brand new Fenix PD 35 can be equipped with "violence".
On the other hand we read in the relevant specialist forums repeatedly that lamps should be better equipped with only a battery with a maximum of 2600 types. Fortunately, I still have some older AW batteries that are slender and fit in really every Fenix lamp.
The first experiences with the ENERPOWER batteries confirm the expected long term. It's definitely a good feeling to carry around Japanese brand goods and not dubious Billigkram with it.
