Hi all, So I just goy my new xtar vc4 and have a question about the mah readout. I put in a set of sony vtc4's and they charged fully to 4.2volts, however the mah readout is displaying 1678 on one battery and 1698 on the other. I was under the impression that they were 2600 mah batteries? Is there a reason they would be reading so much lower? Thank you for any input.
