Sony NH AAB4E - Camera battery 4 x AA NiMH 2500 mAh

I purchased a Sony camera with an earlier version of these batteries. They were made in Japan and are still working after 6 years. I needed spares so I purchased a 4-pack of the NH-AA-B4E batteries. When I received them I noticed they were made in China. The first two I used were not even close to the performance of the Japanese-made Sony's. They do not hold a charge. For a couple of years I struggled with them as backup batteries with the original Japanese-made Sonys doing the heavy lifting. The Chinese-made batteries eventually became virtually useless even as backup batteries so I put the second pair into service. I fully charged them on my Sony recharger and put them into my camera. I turned the camera on and the lens extended. I took five pictures and the batteries died so badly the lens did not retract. Normally when a battery pair is exhausted the lens retracts but these batteries failed so utterly and completely the lens stayed extended. Meanwhile the Japanese-made batteries are still working.

I wish I could give these new Chinese-made batteries less than one star because they really are worthless junk.

I bought these batteries for my Apple wireless keyboard and also for Nikon external flash. They work great and Hold charge for a long time. Highly recommend.

We used these batteries for an electric buggy competition, and Sony batteries worked significantly better than other types we tried.
