K5 and K5 II Batteries

Reconman-1033 · 10-26-2013, 09:00 AM

The battery for the K5 II has four contacts. The battery for the K5 has three contacts. Are they interchangeable?

My K5II battery has three contacts.

Thanks. I recently purchased a K5 II to move the K5 to backup status. The K5II came with a four contact battery and charger that does not accept the K5 (D-LI90). In lieu of a previous thread discussing battery problems on the K5, I have been reluctant to interchange them.

That helps.

What is the name of this 4-contact Pentax battery? Maybe it is not genuine?

It is genuine. I have both but have only used 4 contact in K5IIs.

All of my batteries have 3 contacts, from k-5, k-01 and k-5IIs. Maybe different standards in different countries?

I just checked and my K5IIs came with a 3 contact battery and charger.

Probably Pentax at some point moved from 3 contact to 4 contact batteries/chargers.

I don't think so.

Both K5IIs bought in Europe and K-01 bought in USA came with 3 contact batteries/chargers.

Folks:
Thanks for your input. I did a little further digging and discovered the following on the Ricoh website link for downloading the latest firmware for the Pentax K-5II and K-5IIs

"Preparation of update
•Blank, formatted SD/SDHC card (32MB or more)
•USB cable I-USB7
If you are copying the firmware update file to the SD card by connecting the camera directly to your computer.
•SD card reader or a computer with a SD card slot.
If you are copying the firmware update file to the SD card using a memory card reader / writer.
•Fully charged battery (D-LI90)
*Be sure to use fully charged battery (D-LI90)"

Consequently, I am concluding that the three contact battery (D-L190) is compatible with the K5, K5II and K5IIs.

It may be that the four contact battery (D-L190P) is compatible with the K-5II and something else completely different.
So, if anyone has both the K5 and K5II (or K-5IIs) I hope this gives some direction.

Thanks again to all.

J.T.

The fourth contact has something to do with safety regulations afaik. The two batteries can still be used interchangeably.

After reading all those warnings with Lithium-ion batteries and remembering the laptop fires, I'm thankful I use eneloops with my Pentax cameras.
