IKEA has three options as chargers for the LADDA NiMH, rechargeable batteries.
Unfortunately IKEA web site management team, they are unaware of technical content, and because of that, actual charger electrical specifications they are not delivered.
This topic is here to inform of electrical specifications.
Battery Type ------ LITOSFAR --- TJUGO ---- Stenkol (Four cells charging simultaneously)
AA 1900 mAh 240 mA 210 mA 350 mA
AAA 750 mAh 120 mA 110 mA 200 mA
Technically:
Stenkol this is the fastest of all three ( Four bay ), production date 17-09-2021.
LITOSFAR this is faster at eight bay class.
TJUGO this is just a bit slower than LITOSFAR.
All three chargers they are considered for home and family, they support low speed of charging.
Low speed of charging, this is great for battery cell extended life cycle.
From the other hand, if they are in the house kids and battery powered toys, I would recommend getting a Normal Speed charger.
This is also considered as three hours charger, this it should support 600mA per AA bay, and 300 mA per AAA bay.
Unfortunately the low priced market of chargers, this is messed up, all chargers at Amazon they are junk.
All chargers at Aliexpress they are junk.
IKEA chargers, they are inspected electronics, but slow performing.
Many people do not understand that, IKEA LADDA this is new technology of NiMH, these made by a portion of recycled material.
Fast charging speed this is the Max, that they can tolerate.
If you do not have money to spare for a fast charger, then get a quantity of three Stenkol instead, along of three packs of batteries for your application.
