I don't think you've tried
any D-Li90s in your K-30, since it uses the D-Li109.
The '109 is considerably lower in capacity than the D-Li90, with only 1050 mAh, compared to 1860 mAh.
To the OP, it's worth pointing out that the Amp Hour ratings on 3rd-party batteries vary widely. I've seen 3rd-party D-Li90s from 1400 mAh to 2900 mAh - more than a 100% difference! Even though that is the capacity they
claim, not necessarily what they
deliver, it's worth the time to look closely at the battery specs, and not just the price tag.
