For five years, LADDA batteries were sold in IKEA stores, their characteristics do not differ from the world's best Panasonic Eneloop batteries, but the price of LADDA was several times lower. Last year, the design of IKEA LADDA changed - they are now gray. The main question that worries everyone is whether the batteries themselves have changed.
Most IKEA stores sell AA 1900 mAh batteries (549 rubles for 4 pieces) and AAA 750 mAh (449 rubles for 4 pieces). For both types of batteries, a service life of 1000 charge-discharge cycles is indicated.
There are also 2450 mAh batteries on the IKEA website (749 rubles for 4 pieces), but they are rarely in stores. They have a declared resource of 500 cycles.
All of these batteries are manufactured in Japan, most likely in the same plant where Panasonic Eneloop and Fujitsu are made.
I recently learned that the Analyzer of Chemical Power Sources Yarostanmash ASK2.5.10.8 not only me, but also the video blogger Admiral134. Using this device, he investigated the new IKEA LADDA 1900 mAh and 750 mAh batteries and compared them with Panasonic Eneloop with the same declared characteristics (only Eneloop cycles are specified as 2100).
I believe that there is no point in repeating the same measurements on the same device, so I will just give the results obtained by the Admiral.
Batteries AA 1900 mAh.
The main conclusion is that the new IKEA LADDA are good batteries, but they are NOT the same as the Eneloop. LADDA has a quarter more internal resistance ~ 25 mOhm versus ~ 20 mOhm and a little more self-discharge - 13-14% in 28 days versus 10% for Eneloop.
Batteries AAA 750 mAh.
Here, everything is also excellent with the capacitance, but the difference in internal resistance is even greater - LADDA has 45-48 mΩ, Panasonic Eneloop has about 24 mΩ. There is no data on self-discharge yet - the video with the main testing was released on October 24, most likely the results will be by the end of November.
Here is a video of the Admiral's tests.

The global conclusion can be made as follows: IKEA LADDA 1900 and 750 mAh are cheap and good batteries. Their capacity is even higher than stated. The slightly higher internal resistance compared to the Panasonic Eneloop only results in a slightly lower battery voltage under very heavy load. Although the self-discharge of LADDA is higher than that of Eneloop, it is much less than conventional batteries (both LADDA and Eneloop refer to low self-discharge batteries, LSD). I believe that at such a price, all these shortcomings of IKEA LADDA batteries can be forgiven.
