At church we use several Ansmann Energy 16 chargers and Tenergy 9V batteries. Long story short they've been good to us but lately not so much. The charge indicators on the stations fade and it all seems not to be all that reliable anymore. Fairly new NiMH batteries peter out in the middle of a service and so on. No complaints, we got enough life out of this setup. So, looking for a new solution here. We have to stay with 9V because the (expensive) wireless mikes need these and I'd would like to move to 7-cell instead of 6-cell. Read some good reviews about the Maha/Powerex brand:
They also have low discharge 9V 230mAh batteries which sounds nice. However, I am not familiar with this brand. Maybe someone here is? Or knows of even better systems?
Must be fully automatic, meaning stick the batteries in there no matter what their remaining charge is and leave them in the charger until next Sunday.9V batteries with two LiIon cells in there are, of course, the ultimate cat's meouw. But they seem not to be ready for prime time yet, I could not find multi-bay chargers and I am afraid someone will accidentally stick them into a regular charger and .. KABLAM.
