It sounds as though you have a drain on the battery with the ignition off.
Since your battery is still fully warranteed I would have it checked first where you bought it along with the charging system. Usually you can have that done at no charge. If all checks out fine then suspect a parasitic drain on the battery. That can be diagnosed and pinpointed very easily. If you are up to doing it yourself, disconnect the neg lead from the battery and connect a voltmeter (measuring amps) between the neg. batt. terminal and cable. For your car you should probablly read less than 50mA (milliamps). If it is appreciably higher than this, you know you have a parasitic drain. To islolate the circuit in suspect, start pulling fuses one at a time (then replacing them) until you see the amperage drop below 50mA (or even lower). Once you have isolated the circuit, you can remove the fuse overnight until you have the problem fixed. Hope this helps
