The LADDA brand of batteries is owned by IKEA and there are rumors that they are the same as the Eneloop Pro batteries, but much cheaper in terms of price and that is something that we do plan to check and confirm soon. After we make up to date tests of the latest Eneloop Pro products as our Eneloop XX AAA test data is already quite outdated. Do note that not all of the LADDA batteries are the same as some of them are made in China and others in Japan, like the 900 mAh AAA ones made in Japan is the same factory that apparently produces the low self discharge Eneloop batteries. These IKEA LADDA batteries are rated at 900 mAh typical capacity and they do seem to deliver a bit more according to our tests at lower loads making them get a good rating from us thanks to the low price you pay for them.

1.2V AAA 900 mAh LADDA NiMH batteries manage to deliver more than 900 mAh (their capacity rating) at lower current loads of 0.1A and 0.2A in our tests, going up to 0.5A load the capacity you get is still quite good, although a bit below the capacity rating. At 1.0A load which is over the battery capacity rating the usable capacity gets lower, but that is kind of to be expected. Overall very good results for the price you pay for these IKEA batteries, though probably they are best for low to mid-range loads.

The performance of the 1.2V AAA 900 mAh IKEA LADDA NiMH batteries in our tests:

– 926 mAh at 0.1A load
– 925 mAh at 0.2A load
– 863 mAh at 0.5A load
– 588 mAh at 1.0A load

– 1.153 Wh at 0.1A load
– 1.137 Wh at 0.2A load
– 1.013 Wh at 0.5A load
– 0.614 Wh at 1.0A load


The 1.2V AAA 1000 mAh BTY NiMH batteries are something that you may find in a lot of Chinese online stores as well as on eBay and what you will notice for sure with these batteries is that they are being sold very cheap for 1000 mAh capacity. The fact that these rechargeable AAA batteries supposedly offer very high capacity of 1000 mAh (among the highest for AAA size NiMHs) and their very cheap price should raise an alarm that the capacity rating is most likely lower than advertised. Normally in such cases it is a wise idea to avoid getting such batteries, but we got a pack of four in order to be able to test them and see what is the actual capacity that these batteries are providing and how much it differs from the advertised 1000 mAh. We were prepared for nothing more than half the advertised capacity, but going through a Break-In mode on the MAHA C9000 Charger/Analyzer we were not prepared for such a disappointment. On the photo above you can see the minimum and maximum measured capacity of the pack of four batteries and you will get why we were so disappointed. In fact what we got as available capacity was as follows: 134 mAh, 140 mAh, 144 mAh and 161 mAh and that is from batteries that are being advertised as being able to provide 1000 mAh capacity, not worth buying these regardless of the price, hell they are not worth even if somebody gives them to you for free.

Avoid buying 1.2V AAA 1000 mAh BTY NiMH batteries, they are really not worth it!!!


The 1.2V AAA 950 mAh Sanyo Eneloop XX NiMH batteries are of the third generation of Eneloop batteries from Sanyo and are the model designed for powering high current consuming devices such as photo strobe flash lights, wireless keyboards, mice, game controllers, radio controlled toys and a range of household devices. Eneloop XX is the preferred battery by many photographers for powering their photo flashes and other photographic equipment and even on the batteries you can see written “High capacity eneloop for professional use”. The Eneloop XX series is also from the Low Self Discharge type NiMH batteries and can retain up to 85% percent of its capacity after an year of storage, but these batteries are designed to offer up to 500 recharge cycles mostly due to the fact that they are designed to handle higher loads unlike the standard low-to moderate loads and up to 1800 recharge cycles for the standard Eneloop batteries. These Sanyo Eneloop XX batteries come with a typical capacity of 950 mAh, but their minimum guaranteed one is 900 mAh and on their packaging you can only see the minimum and not the typical capacity written, though they are sold as 950 mAh. They come pre-charged with 50% of their capacity and our measurement for the initial discharge provided between 395 and 401 mAh which is pretty much within the 85% for batteries made in 12-2012, but let us see how they will perform fully charged.


Starting the tests of the 1.2V AAA 950 mAh Sanyo Eneloop XX NiMH batteries with a low constant current discharge rate of 0.1A got us 925 mAh as useable capacity or withing the range between the minimum guaranteed and the typical rating of the batteries. We are used to seen such results from Sanyo with low current loads, but the Eneloop XX batteries are supposed to really shine when they are stressed with higher power requirements. And when increasing the constant current load to 0.2A and 0.5A they still manage to perform great, even at 1.0A they manage to perform really well. These Sanyo Eneloop XX batteries really do great job in providing what is advertised, and though they are not the best performing NiMH batteries in general that we’ve tested, they still do a great job for a high-capacity LSD NiMH solution.

The performance of the 1.2V AAA 950 mAh Sanyo Eneloop XX NiMH batteries in our tests:

– 925 mAh at 0.1A load
– 856 mAh at 0.2A load
– 827 mAh at 0.5A load
– 689 mAh at 1.0A load

– 1.153 Wh at 0.1A load
– 1.047 Wh at 0.2A load
– 0.954 Wh at 0.5A load
– 0.733 Wh at 1.0A load
