I ordered 4 NiMh 2300mAh batteries with tabs. I usually analyse all batteries and discharge them before soldering the battery pack in order to have all the cells balanced between them.

In the last order, one of the batteries gave roughly 1Ah, which is much less than the stated 2.3Ah.

It is normal for the batteries they sell to give lower than stated capacity. 2.3Ah cells usually only give 1.7Ah, but that is acceptable for me.

What is not acceptable is that I wrote them about this issue and they haven't even answered. I asked them for support on the issue and they completely ignored me.
