Testing the Capacity of IKEA LADDA NiMh Batteries Made in Japan

It is said that IKEA LADDA branded NiMh rechargeable batteries come out of the same factory as the revered Eneloop batteries. Eneloop batteries are made in Japan, as are these. These AA cells are offered in 2 capacities, 1,900 mAh and 2,450 mAh. 1,900 is about average capacity for a battery of this type, 2,450 is towards the higher end of the range. The batteries call for a very slow charge, 190 mAh for the lower capacity cell and 245 mAh for the larger capacity cell. This is much slower than any typical battery charger I've seen. The majority of the packaging is not in any language I understand, but I think it claims the smaller cell will last 1,000 charge cycles and the larger will last 500 charge cycles. Larger capacity NiMh batteries will accept fewer charge cycles than a smaller capacity NiMh battery. I find it hard to believe this difference is double the cycles for a ~500 mAh difference in capacity. I suspect at the end of the batteries' lifespan, actual usage time would end up being a wash as one lasts longer per charge but takes fewer recharges, while the other lasts less per charge but takes more recharges. I tend to opt for the slightly lesser capacity cells for batteries like this as sometimes the highest capacity ones are ever so slightly physically larger and fit annoyingly tight into the battery compartments of some pieces of equipment. I have not yet determined if that's the case with these or not. The batteries were manufactured about 6 months prior to the taping of the video. I don't know exactly when these were purchased, but assuming they were purchased very recently, that seems like a long time for something with a shelf life. Regardless, the batteries did test as having a full charge when removed from the packaging. I tested 2 of each capacity cell. The capacity test results were as followed: 2,450 mAh cell: 2,631 and 2,622. 1,900 mAh cell: 1,803 and 1,797. These results were surprising to me. I was expecting both cells to measure just slightly above rated capacity, perhaps by 50-100 mAh. Instead, the larger cells measured considerably above capacity and the smaller cells measured slightly below capacity. Each of the two cells tested with a very similar capacity to each other, which would lead me to believe the manufacturing process has very low tolerances. Most battery manufacturers claim the cells need to be charged and discharged a handful of times before full capacity will be achieved. These numbers may go up after the first few uses. I will perform multiple discharge/recharge cycles with the charger then test again to see if the capacity has changed.
