Grey IKEA LADDA AA 1900 and AAA 750 are equivalent to white Eneloops of the first generation, of in total 5 generations til today …
The 5 generations of white Eneloops mainly differ with regard to the number of cycles they can achieve and a little bit concerning the self discharge rate over years, while the capacity stayed the same for a long time :
Gen 1 : 1000 cycles
Gen 2 : 1500 cycles
Gen 3 : 1800 cycles
Gen 4 : 2100 cycles
Gen 5 : 2100 cycles, but “min. 2000 mAh” instead of before “min. 1900 mAh”
IKEA Ladda grey AA and AAA are marked with “1000 cycles”, that corresponds to the 1. generation of white Eneloops …
The cycles shown above result from the test according to the IEC standard of 2011, nowadays Panasonic additionally provides the number of cycles according to the IEC test of 2017, which is meant to be more realistic, for white Eneloops of the 4. and 5. generation that means “600 cycles” …
so the grey IKEA Ladda are not really equivalent to white Eneloops of today, in practice they have a shorter life, which was proven in a test, where the Ladda AA 1900 grey did not reach half of the cycles of a white Eneloop AA Gen 4 …
but of course you could call the Ladda a good value for the lower price compared to white Eneloops …
