I have a high-quality battery charger, and gave away the charger of the bundles.
Already on first load the batteries reach maximum 2.2 Ah - what would have been manageable at the price.
After 2 charge / discharge cycles is my radio alarm clock, in which the batteries are used, assumed without warning.
Result: 2 batteries have a shorted cell, were no longer detected by the battery charger, and reported
a voltage of 2 mA. I have briefly manually missed them a pulse, so the charger you ever seen again - and then the Refresh program (while the battery is repeatedly charged and discharged to no longer changes the maximum capacity) run.
Result: 1 battery has no longer can revive, 1 battery has 1.7Ah, 1.3Ah battery 1 of the third to 600mAh remaining capacity.
The batteries of the "favorite discounters the Germans" are more favorable, even covered in terms of capacity, but: They are much more durable and achieve even after 10 charge / discharge cycles even an acceptable capacity.
I would not buy this product.
