Out of curiosity I made an inventory which batteries are used on Pentax camera's, to see if there are any patterns. The list below is derived from the manuals on the Ricoh Japan web site. The Optio camera's are not included (too many of them).

All batteries are of type Li-Ion. The standard CR-V3 battery is replaced by custom types in various configurations after 2007.
It seems Pentax is trying to re-cycle a battery type for as many camera's as possible. An interesting series is K7, K5, K-01, K5-II(s), K3, all using the D-LI90. Another example is the D-LI92 which is first applied in the X-70 (2009) and later re-used in the WG's.
A Pentax speciality is also that most camera's can adopt AA batteries, direct, with an optional battery holder, or with a battery grip. I think this is a strong point and well appreciated by many of us.
This list can be used as is, but if you have any supplementary info or know-how's you can post here too.
