I've had two Wasabi go 'dead' after a couple of years but that was because I wasn't using my K30 at all for about six months. You've got to 'top off' Lithiums about one a month or they will go bad and not take a charge. I've had good luck with them otherwise (on 4 cameras)
My information is the opposite. The best way to store Lithium Ion batteries is 40% of capacity.

How would you determine 40%?

i've heard exactly the same thing. Although, in practice, i store them full, and rotate them through. so the last charged one goes in the bottom of the pocket, the bottom one moves up a slot, and the top one goes in the camera. (i have a pocket in my bag that holds 2 batteries) Havn't had a problem yet, and it seems that i go through them fast enough that they're fully charged whenever i need them. Longest they sit is maybe a couple of months between charges.

That sucks. Is it swollen
It came with the camera I bought from a member here. I didn't think to check if it's swollen or not. Will do that today, could be, but other than it getting stuck, it seems to work fine. I only use it in an emergency.

More on battery storage:

"If the battery is going to be stored for several months it's a good idea to take it out and recharge it after a few months. Better yet would be to actually use the battery every few months and then leave it partially or fully charged."

The article actually talks about that. I'm not honestly that sure. For me I would shoot for about 50% knowing roughtly the life I get I would shoot half that many shots and then measure voltage and hope for the best.

For my active camera's that's what I do also. But now that my K50 is moving to backup role I have to reconsider. My rotation was more like a couple of weeks on my K50 prior to the acquisition of the K3 so I never worried about the full battery status.

Fully Charged is OK - but not preferred. However it is better than discharged. Partially charged must be over a certain voltage level to help with the problem. Read the article I posted - it's pretty universal from what I have seen. The details in that article were what made me select it.

hmmm... seems like you want to keep your battery only 50%-75% charge? just averaging out what everyone is saying.

but also once in a while draining and fully charging the battery.

Interesting..... maybe i'll give wasabi a try.

Drain and fully charge is more of a NiCad requirement than NiMh or LiIon.
