Batteries no alternative in this size

Available in sizes AA or AAA there are many battery alternatives, also very good (for example, Sanyo).
Baby C batteries of this quality but there is no other manufacturer:
high load capacity, low self-discharge, so far no failures, even after many charging cycles.

I invite to a Aldi charger and use the batteries in flashlights and mobile sound systems.
After several unsuccessful attempts with other supposedly non selbstentladenden batteries (Conrad electronics), who gave up the ghost after only a few charging cycles, I use only the Ansmanns.
