Nikon D40 battery change? - charging camera batteries nikon charger for the en-el9

OK, so I have a Nikon D40. Heres the situation briefly described below:

- The battery is almost empty, so I took
- Entered into the load as cartridges
- The orange light was on my charger, indicating that the battery be fully recharged
- Take the charger and the battery in the camera and turn on the
- Fire briefly go empty just to hold, since there is no "Battery low" power

What does this mean? Do you think I should change the battery on my purchase (a new one), you buy a new charger, or do you think of the camera itself the problem is here?

Personally, I think the battery. Incidentally, the battery, I'm going to read, it is not AA or AAA or something. It is a real Li-ion Battery EN-EL9 is specifically for Nikon D40 (I) or the D60.


However, any person who, or maybe something like this you can be a problem that I had no knowledge have been identified by me, let me know what you think!
I'm sorry that the problem is friggn! ...

A new battery on the Nikon website is $ 50. And then you go to where I live will cost another 50 euros, no lie. There are no shops on this small island, looks to me like a Nikon rechargeable battery is available separately, if necessary.

Please read and answer, if at all.
