I have one Wasabi and two Pentax (*) batteries for my KP. I've noticed that when I use my Watson charger {which I like because it gives me a running measure of battery charge in %}, the Pentax batteries charge until 100% and then goes into idle, while with the Wasabi battery the charger shuts off around 95%. Over an entire week, my usage is low enough that I never completely drain even two batteries so that is not an issue for me, but even so, it is something I've noticed.
I got the Wasabi battery because Wasabi and Pentax batteries for my Q-7 behave exactly the same on that same charger.
(*) I have one that came with my K-30 {I've been using AA batteries with it} and one that came with the KP
