No, I thought that was the case when I first bought my ZX, check your alternator and work from there. if the battery dies it could be the charging system or the battery is bad or going bad. Use the FSM on electrical http://www.xenons130.com/reference.html and read through the trouble shoots. The fan may seem like its the cause but it bearly is running on the battery but it could kill the batt if the charging system isnt working properally.
