K5 battery charger. LED flashing

I've a three-month-old K-5ii, with a three-month-old genuine battery.

Yesterday morning I put the battery on charge and the LED started blinking instead of lighting constantly. I tried removing and reinserting it, with the same result each time. The manual tells me it means the battery needs to be replaced.

I tried it back in the camera and it seemed to have no power at all. Fortunately SRS had originally supplied a spare aftermarket battery with the body, and that saw me through the day.

Last night I dug out the receipt and was all set to go to SRS today for a battery swap when I thought I'd try it one last time. And this time it charged as normal.

Has anyone else had this on a K-5/K-5ii/K-5iis? Is it just one of those things that happens with a K-5 charger every now and then? Or is it indeed the sign I have a bad battery?

The only thing I can think of that I did abnormally the night before the problem was to absent-mindedly leave the SD card door open overnight, with the card itself in my pc's card reader. The camera was powered down. I replaced the card before I removed the battery in the morning. Could that somehow have caused a deep discharge?

I tried to use my I10 recently and it would not show any sign of life when switched on. The battery charger light blinked as you described when I inserted the battery but went steady after a while. I put it down to the battery having no power to communicate with the charger until it's charged a bit. I've had no trouble since.

Dirty contacts perhaps?

Thanks, Barrie.

That's what I'll think I'll do. Continue using it as normal and see if it re-occurs.

Thanks, Ken.

Possibly I suppose. But only 3 months/3,000 activations old and the contacts look like new.

I bought a brand new K-5 with the 18-135 WR Lens from Henrys of Toronto this January.
I put the Pentax battery for charging in the supplied charger. The charger LED started flashing. I cursed Pentax-Ricoh for a bad battery, but then I took a Johnson Q-tip, dipped it in pure hospital rectified spirit and cleaned both the battery and charger contacts.
Presto the LED lights no longer flashed and the battery was fully charged in about 6-7 hours.
I think the battery terminals build up a thin film on contact with polluted air. So it is good to clean the contacts now and then.
