The 1.2V AAA 900 mAh Turnigy LSD NiMH batteries are Low Self Discharge NiMHs as the name suggests, meaning they do loose less of their useable capacity over time compared to traditional NiMH batteries. Turnigy is a brand of one of the largest online RC model stores, namely Hobby King, so these batteries are often used for radio controlled models – for powering transmitters, receivers and even smaller scale models. The price of the Turnigy LSD NiMH batteries is more attractive compared to other similar products, but what about their performance, we are going to find out exactly that now.

We have started the test of the 1.2V AAA 900 mAh Turnigy LSD NiMH batteries as we normally do with a low constant current discharge rate of 0.1A and getting 1068 mAh as a useable capacity is really a good result with significantly higher capacity than what the batteries are rated. In fact the performance of the 900 mAh Turnigy LSD is very close to the one provided by the 950 mAh Powerex Imedion LSD NiMH batteries that we’ve tested recently that also performed great. Increasing the load we test at and we still got great performance out of the Turnigy batteries, so they are great and affordable solution and the only problem is that you can only order these online from some of Hobby King’s warehouses in different countries.

The performance of the 1.2V AAA 900 mAh Turnigy LSD NiMH batteries in our tests:

– 1068 mAh at 0.1A load
– 988 mAh at 0.2A load
– 909 mAh at 0.5A load
– 836 mAh at 1.0A load

– 1.318 Wh at 0.1A load
– 1.203 Wh at 0.2A load
– 1.076 Wh at 0.5A load
– 0.948 Wh at 1.0A load

1.2V AA 2400 mAh NiMH Turnigy LSD Battery Tests

The 1.2V AA 2400 mAh NiMH Turnigy LSD batteries are NiMHs of the newer Low Self Discharge type that retain significantly more of their capacity over time as compared to the normal NiMH batteries that have faster self discharge. According to Hobby King selling these batteries they should not loose more than 30% of their charge in the course of a year when not being used. These Turnigy LSD batteries are rated with 2400 mAh typical capacity and not maximum capacity, though we are going to check if that claim holds true or not.

Official Specifications:

– Category: AA batteries
– Capacity: 2400mAH
– Voltage: 1.2V
– Chemistry: NiMH
– Weight: 29g
– Dimensions: 51x14mm

We started testing the 1.2V AA 2400 mAh NiMH Turnigy LSD batteries with initial discharge to see what capacity they still had when we got our order from the online store in order to check their LSD capabilities. The capacity provided was about 60-65% of their typical rated capacity, though we don’t know when they were produced, but according to the claim of about 30% discharge per year they should be made about a year ago. The minimum initial discharge capacity we got was 1505 mAh and the maximum one 1543 mAh from four different batteries that we tested with.

The 1.2V AA 2400 mAh NiMH Turnigy LSD batteries have managed to provide very good results in our tests providing 2380 mAh with a discharge rate of 0.2A that we tested as a minimum discharge rate and that is pretty good. The batteries also handle very well under high current constant discharge loads of 2A that was the maximum we tested with providing 1240 mAh. We do our tests of NiMH batteries at a constant current discharge rates of 0.2A, 0.5A, 1A and 2A or with about twice higher as compared to what we test Alkaline batteries at due to the fact that NiMH batteries tend to provide higher capacity and are able to handle better higher current draw.

The performance of the 1.2V AA 2400 mAh NiMH Turnigy LSD Batteries in our tests:

– 2380 mAh at 0.2A load
– 2149 mAh at 0.5A load
– 2139 mAh at 1A load
– 1240 mAh at 2A load

– 2.920 Wh at 0.2A load
– 2.553 Wh at 0.5A load
– 2.402 Wh at 1A load
– 1.270 Wh at 2A load

In overall the 1.2V AA 2400 mAh NiMH Turnigy LSD batteries are performing very well and are available at a very good price online, though the shipping cost makes it worthwhile only if ordering more batteries as these are only being sold online and shipped from Asia.
