Watson NP-BX1 Reviews

Batteries fully meet their specifications

By Kenneth
Rated 5 out of 5
Date: 2026-05-24

Upon testing with an Opus BT-C3400 battery charger / tester, one of the two Watson NP-BX1 batteries I received tested at 1,143mAh, the other, 1,164 mAh. The former weighed 20.88g, the other, 20.95g. A now 7 year old Sony NP-BX1 tested at 1,148 mAh and weighed 24.4g. (I think the Sony lost some capacity over the years.) All this testing was done recently, May 2026. So, the Watson batteries fully met their specification and they will be very useful. Thanks for carrying good stuff, B&H! Seven years ago I also bought 4 no-name NP-BX1 batteries marked 1,240 mAh. Upon recent testing two of them were about 600mAh, and the other two about 650mAh. Clearly they never had anything close to their advertised capacity. Finally, the attached image shows the setup I used to connect NP-BX1 cells to the BT-C3400. I am using the shell of what was a terrible charger to hold up to three NP-BX1 cells, and provide electrically independent AA size adapters for each cell.

Yes I know that one of the many, many cool features of the Sony RX 100 VII is that it can charge it's battery onboard the camera. And I bought the M7 because of the size, weight, and simplicity of fewer accessories and parts to schlep. But for my upcoming travel adventures, for the price of a Sony battery alone, I now have a spare battery and a dedicated charger (With an additional USB A charging output) in a tiny package. I have tried the minimalist route before, and the anxiety of running out of juice is too great for these once-in-a-lifetime trips. I'll leave a pair of socks out if I have to, but I love having a dependable charger and spare batteries on trips abroad.
