Originally posted by ruemiser I see mutiple listings for batteries for the K10d for the D-LI50, but many differ as far as the amps. My original is listed as 7.4 V and 1620mAh.
Note that "mAh" is milliamp hours, a different measurement from amps (or milliamps). An amp is a measure of actual current, whereas amp hours tells you the capacity.
This is important because while wrong amperage or voltage may be a cause for concern, a higher or lower "mAh" just means it's slightly bigger or smaller in nominal size. I say nominal because in practice (especially in third-party batteries) the labels tend to be far off from reality and can vary significantly from battery to battery.
