Battery problems - help/advice please

Hi all,

I have a problem with my 2nd battery in my K20D.

I fully charged it a couple of days ago, went out last night and it depleted after 5 long exposures, it was in the grip and set to use first. (5 min was max exposure)

I put it on charge today and the little red light went out after about 10 seconds!

It is a INOV8 D-Li50 same as the regular Pentax one.

They were both bought at the same time from SRS 25 months ago.

Should this have happened? Is this normal life expectancy for a battery? In 2 years I've only taken about 11,000 images, and no idea how many times I've re-charged them, but prob not that often.

Any other members had similar problems or can shed some light on the for me.

Thanks

I suspect it wasn't fully depleted. If you had tried the grip battery in the camera then I reckon it would have worked fine. I had this issue but it was one of many so I didn't really explore it fully as other issues were more pressing. I did google and found a couple of other mentions of this situation. I think it is a battery management problem rather than a battery problem.

Thanks Adrian, I have just tried your suggestion and thought it was working, but after about 15 mins the battery has died/depleted in the body now.

Oh, well you are lucky. Better a problem with a cheap battery than an expensive camera.

lol, true Adrian very true...

Have you thought about going back to Inov8? http://www.inov8-memory.co.uk/batteries.php

They may say 2 years but could be worth a try as you are only just outside.
