LP-E4 Oddity

Thanks,
I had read this, but it's different in that in all those cases, the batteries would not take a charge, and the charger said they were poop.
In my case the chargers love them and whisper sweet nothing in their ears while gently fully charging them and saying they don't need reconditioning etc..

Also, the LP-E4n was the beginning of this weirdness, and it works great in the 1DXII.
Can anyone confirm that an LP-E4 will even work in a 1DXII?

If the PCB were bad, wouldn't the charger reject them? I haven't put a meter on them yet, but I will do so tonight.

LP-E4 will work in 1DXII but max fps will drop from 14 to 12 according to Canon.
I confirmed it at least works when I accidentally posted my LP-E19

So you have a sticky battery switch? That is odd, but I wonder how you can fix that. Perhaps a drop of rubbing alcohol or a drop of wd40 placed carefully with a toothpick perhaps?

You missed something a post or two back, It wasn't the camera at all,. apparently there is something wrong with my charger!
It is doing something to the batteries to make them dead. It explains the suddenness of it all, and that it happened to two batteries at once.

I just took the 2nd "bad" battery off the the 1DXII charger, and now it too is functioning perfectly! Better than perfectly, it's back up to three bars! (from two before)

So first the new 1DXII charger had fixed my only LP-E4n,. but I did not realize it.

then I apparently killed my old LP-E4 batts with the apparently defective 1D4 charger.

Now the 1DXII charger brought both of them back to life.

I'm struggling to follow the troubleshooting order of things [1st beer of the day completed successfully] but I'm pleased to hear you've got something working

Well, imagine how long I've been struggling!!

I knew something was really off here,. but just could not imagine that it was the charger seemingly working fine, but actually sucking the life out of the batteries!

It's just like you found some money... Two working batteries again.
