you could still have a bad battery.
even at full charge a bad battery may not work that well, or at all.
take it to a checkers and they can charge and check it for you.

OK...Before assuming a bad battery, some basic troubleshooting needs to be performed.
Charge the battery fully and unflood the car. Hopefully it will start after the unflooding. If not, check for spark and fuel.
With a fully charged battery, the car should crank properly. If the engine is turning over slowly then check the basics. Make sure the battery cables are clean and tight at the battery. Check the main ground cable at the drivers shock tower (down near the frame rail) and on the starter bolt. It needs to be in good shape. Make sure the main + lead to the starter is decent as well.
Loose battery connections will cause the same symptoms as a dead battery. If the car cranks slowly, it will probably flood.

there are three things you need to start a car.
fuel, air, and spark.
most the time something is wrong with the spark part of it.
arroncake brings up good point though, in always trying to start it you may have flooded it.
so yeah, do what he says and then check all the stuffs.

what year is the car?
Do you have jumper cables? And another car?
If you have another car handy and the batteries are the same, swap them, if your battery starts the other car, it's probably fine. And if that battery won't start yours, well, then you know for sure it isn't the problem.
1st gens have issues with the + battery cable, it's made out of aluminum (cheaper and lighter than copper, I suppose) - but they wear out over time and won't transfer the current to the starter anymore.
2nd gens don't tend to have the same issues but can sometimes.

"Deflooding for Dummies"
If the car is flooded and you don't know how to deflood it, this is what you do:
pop the hood and look in the fuse box which is located to the right of the radiator (if you're standing directly in front of the car).
Pull out the EGI fuse.
Start the car and let it crank for a good 10 seconds.
Quickly replace the EGI fuse and try to start the car again. If you're lucky the car will fire up on your first try, but it's not always the case especially on cold days. It's easier if you have a friend help you and have him plug the fuse back in after 10 seconds while you're still cranking. Loads of white/blue smoke will pour out when you're done, don't worry about that it's just unburned fuel and it'll go away shortly.

Usually the engine will Make a Chug sound,when Rolling over.That is a sign that it is making Good Compression and the Car "usually" starts..If the Car is Flooded,it makes a Whirring sound,and it is a Distinguishable sound.Different than the "chugging sound"..So,This Whirring sound Is the "tell tale " sign that the car is Flooded,and Has Lost some Compression because there is too much Fuel in the Housings...NOW: first of all get a Well charged battery.Then Pull teh Plugs,NOTE the Location of the wires in Relation to the Plug.Mark them With Colored tape if you have to.Take the wires off,.take the Plugs out..the TOP plugs are DIFFERENT than the Bottom Plugs,so Do not Switch the Plugs..Clean them Up..There is a FUSE on the Fuse Block by the engine..take out the TWO fuses closest to teh Engine.They are the EGI fuses(electronic Gas Injection I believe).They cut the Power to the injectors..So now you have the Fuses out.Roll the engine over about Ten seconds..Put a Good Squirt Of Motor oil into the plug Holes.Roll the engine over about 4 seconds.That will create a Small film of oil inside the Housing..NOW,Throw your Plugs back in,put the Wires back on(CORRECTLY) and then put the Fuses back in..IF The car was Flooded it should start up,Or at least Try to Start/./..NOTE:.for future Reference,the forum has Just about every Problem encountered with teh Rotary Engine all Summarized In Posts,Threads,Comments ETC..,so the Best thing that YOU as a "Newbie" can do,Is Get a cup of Coffee,and Sit back and start reading through the Second Gen Specific and Archives.These Two Sections will give you a Bit Of an Idea as to what the heck you are UP against Since you decided to take the Plunge and Own a Rotary...so,I wish you Good Luck..post with results..STYX!~

2 cents
i know you said you jumped it and it was fine, but if just to make sure turn the engine over by hand with a ratchet make sure it is free. also voltage drop and current draw tests on the starter circuit...although, if the battery is new and cable connections are all sound, it would seems like it would be the starter that is bad...

first of all thanks to everyone who made a response to my problem here, much appreciated
i had a chance to swap the battery with a frend's car today, with my battery installed his car couldnt start and had the exact same noise dat i got from my 7. now we know the battery is drained, but we still dont know what causing it. im gonna have my battery recharge this week and try to start the car again hopefully it will turn over

If the battery is draining while the car is off, suspect the alternator. Disconnect the alternator and leave it overnight. Or, just measure current draw from the battery to the B line with the car of.

u can just take the car to an autozone or kragen and they will load test the charging system for free, at least here in san diego they do. Sounds like ur alternator isnt charging the battery anymore. with the car running and under load for 15 secs the voltage shouldnt drop below 10volts. If it does put a new alternator in and call it a day.

nvm on what i said if the alternator was bad but the battery is brand new it should still start till the battery dies. check the starter and see if ur getting 12v to it when u turn the ignition on. If not check for continuity between the starter and the ignition. im no master here im just trying to help

There is a black 8 gauge wire going to the signal top terminal on the alternator. Unbolt it. Also disconnect the two plug connector on the back of the alternator. Leave the car overnight. Is the battery dead in the morning?

if your alternator is bad then the alternator will drain the battery. if you charge the battery and disconnect the alternator for a night and there is no charge in the battery the next day, your battery is bad. if there still is a charge in your battery then your alternator is bad.
