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.
