Heitech Hei Energy AA

So taken equal to 2 packs and into computer charger.

It seems as if the batteries are sold pre-charged to about 70%, which seems to me which is always good to be pre-charged batteries.

After three cycles (unloaded 250mAh, 500mAh load) it shows me a capacity of 2035mAh pretty much all 8 Battery on.

The recommended charging current is between 200-1000mAh (rapid charging), but Stiftung Warentest found that even no, after 200 cycles, a 10% lower maximum capacity is reached during fast charging with 2000mA after 100 cycles.

Protective charge between 200-500mA should not appreciably accelerate aging.
Incidentally, most users are likely a battery less than 200 times charging, therefore this battery is (also for fast charging) highly recommended.

The battery does in normal (more modern) consumers, especially when comparable amount of energy is needed better services than traditional batteries (primary) (and is much gentler on the environment and Geldeutel).

If there are still any questions, just let it as a comment.
