Hi guys, first post - hope I've put it in the right place...
I just bought a 'genuine' EN-EL9a of ebay and smelled a rat so sent Nikon some pics of it to look at. They say that it is a fake, but it is such a good fake that the only thing they got wrong was the four little notches missing out of the hologram label. It came in perfect Nikon packaging too.
Now I'm thinking that a battery is a battery (normally) but Nikon say there are 'safety devices' in their battery that are not present in the fakes (I have no way of knowing it that is true or not). I checked the voltage after I charged it and compared it to the new Nikon battery that I have and found that the Nikon was 7.2V and the fake was 7.4V. I don't know what the normal tolerance is on these things, but I do know that it isn't worth damaging my new camera.
I also know that if they have the means to make such fantastic copies, why would they make such an elementary mistake as to leave out a component?
Can anybody out there shed any light on this 'safety device' like does it exist? Would using these batteries REALLY cause damage to my camera?
Thanks for any help with this.
