As long as the charger is connected to its power source it will take a small amount of power from that source (even if the phone is not connected to it), regardless of whether it is an AC "wall wart" charger or a cigarette lighter charger (although normally turning the car ignition off turns the cigarette lighter outlet off, so if it drains the car battery the car ignition switch may have a problem). If the phone is connected to the charger it may continue to take extra power even with the phone fully charged (I have a Tracfone that will drain my battery powerpack completely (if not connected to a charger its internal battery drains completely in less than 2 days even if I'm not using it at all -- this phone has something wrong in it).
The real issue is now fast the charger is draining the battery.
BTW, I am assuming above that you mean an external battery that the charger is connected to, not the internal battery of the cell phone itself (if this is the case I would say the phone is seriously defective as this would normally not be possible).

How much does it cost to recharge a cell phone battery?
Only running cost is the cost of electricity consumed to charge the battery through a charger. How many units of electricity is consumed will depend on the capacity of battery, efficiency of the charger (and so losses of energy in the charger in form of heat and radiation). You can estimate the power consumed by the voltage and wattage rating of the charger and how long it takes to charge the phone battery fully. - Neeraj Sharma

Can you use a 9 volt charger for a 6 volt battery?
This is not advised! The 9-volt charger might have a current limiter so that nothing burns up, but it any case if left on it will destroy the 6 volt battery by overcharging. A 6-volt charger is not expensive.
Would a battery made out of lemon and two metals be a wet cell or a dry cell battery?
wet cell battery
Can you use a 12 volt charger to charge 6 volt batteries in recessive situation?
That really depends on how the charger is made. What would likely happen is that the charger would try to deliver more current than it is designed to. The result would be either a blown fuse or diodes in the charger unless it has protection circuits in it. One thing you could try would be a current limit in series with the charger output. A headlamp in series could work to limit the current to somewhere around 3-6 amps and prevent having an overcurrent situation on the charger. Dad calls the light bulb current limit a "rubber fuse" It will take longer to charge that way and you really need to check the battery voltage often making sure not to exceed about 6.75V Be aware that with this method there is no way for the charger to sense that the battery is fully charged. It will continue to try to push to around 14 volts which will never happen until you cause an open cell in the 6v battery. charger + to headlamp bulb, other side of bulb to battery+ B- to charger- That could get you out of a pinch but you really need a charger designed for 6v charging.
If your cell phone will not charge could this be the battery or the battery charger?
If your cell phone will not charge it could be the battery or the battery charger. You best way to find out is to try the battery charger on a similar phone and see if it charges the other one.

Where can I purchase a battery charger online?
Well that really does depend on what type of charger for what battery, i.e. cell phone, regular battery, AA, AAA etc. There are options. I recommend www.ledshoppe.com www.dealextreme.com
Can a mobile charger use as a rechargeable battery charger?
Most mobile chargers aren't really chargers, but rather a power source. The electronics that monitors the charging and stops it when the battery is full is all in the cell phone. IF you hook the cell "charger" straight up to a battery you run the risk of disastrous overcharging.
