Hi,
Don't force it = the levers are latched as part of the security system. There are a couple things you can do.
First, there is a release cable under the passenger side wheel well, locate and pull this cable and the Hood Latch will open, there you can access the battery and get it charged.
Second, you can get and use a Memory Saver -

Finally, there are a number of chargers which will plug diectly into the cigarette lighter to charge the battery directly (assuming it will still hold a charge). This is my least favorite option because I don't like charging through the car's wiring harness to the battery - potential to fry some very expensive components if a short exists somewhere in the system. Not better, convenient, but not worth the risk IMHO. Hope this helps...
Happy Motoring!... Jim'99
