Well, I ignored the little voice in the back of my head that was saying I'd be sorry when I ordered a 3rd party charger, because I could then plug it directly into my 12V of my vehicle, in addition to household power.

Well, I had left my camera on with GPS attached (and the genuine grip--replaced the wiggly 3rd party grip...), and drained both my genuine batteries (yes, I paid for a genuine battery locally). I plugged both of my chargers into a surge bar before bed.

When I got up in the morning, noticed the genuine charger was done but the other wasn't, so I took the 1 battery, and moved the other to the genuine charger, thinking the 3rd party charger was just slow (not too surprising). Once I got back from work that day, popped that into my camera, and it suddenly changed its age from 0 (since it is only 2 months old...) to a surprising 2!

The single charge on the 3rd party charger had stole half of the battery's life overnight!

I'm hoping the seller of the battery charger is willing to compensate me, since I was using it to charge the battery it was listed for charging.

Lessen Learned: Buy and use only genuine parts, whenever possible, especially where major components (grip), or power (battery/charger) are concerned! *Starts saving to get a 2nd charger & replacement battery*

You really think the charged 'aged' the battery and took two years off it's usable life?

It may have... no way to tell at this time. I still have my original D80's battery saying age of 0, and it is about 5 years old!

All I do know is that it did negatively impact something in the battery, and when that was not stated when I purchased it and it said it was designed for my d7k and the battery, I'm going to at least give them the chance to redeem themselves.

Yes, I'd follow up with the seller.

If that doesn't work, perhaps the battery isn't damaged. Perhaps it is just as good as it was and only the lifetime meter has been altered.

Most likely the charger is not fully compatible with the batteries so it did not get a complete charge. Try charging the "old" battery in the Nikon charger and see if it behaves nice.

Did a full discharge in the camera's grip (GPS meters always-on is good for that...) till it swapped to the internal after depleting it, and then a full recharge in the genuine charger... still life of 2
