Three reasons come immediately to mind: First, it was a bad (shorted) battery and it simply went. Second, the charging system is not operating properly. When the new battery was installed, that should have been thoroughly checked, because anytime a battery dies, the cause has to be determined in order to prevent a recurrence. If it wasn't checked, it should be now to be sure it's not, for example, the alternator that's not functioning properly. Third, from my own experience, my XJ had a defective computer running the security system, remote door unlock devices, etc. and it burned a few batteries before it finally burned out the seat memory controls and then they were able to identify it as the cause. They were right, it turned out.

Can you Help as im not sure why but the two different batterys ive used have both gone flat whilst driving my peugeot 206 gti?
If a new battery goes flat the most common fault would be a fualty alternator or regulator on the alternator. The alternator is belt driven by your engine and generates electricity to re-charge your battery. A brand new battery may last a few days but without re-charge from the alternator it will eventually go flat.
Why does a car battery go flat if the car is not used often?
Because Electricity can't be "Stored" as such, it is constant. So wether the car is unused or even something as simple as a mobile phone battery, the voltage is still constant, so it looses power slowly (of course). Until it inevitably "Goes flat" as you put it. - but its often that if any battery is left to long without use or charged. The "effectivness" of the battery begins to deteriate, so eventually. (After a Fairly long time) that battery would become unusableb indeffinetly, regardless of the user , atempting to charge it. In addition if the battery runs flat is just a couple of days then something is on drawing power from the battery or the battery has a dead cell.

Is a flat battery a conductor of electricity?
well, yes. It conducts electricity from one lead to the other. Shape has no effect on the battery other than how its made. So you must be thinking of a simple battery cell process, otherwise this would be a silly question. In a simple battery cell, even if your battery was as thin as a piece of paper it would still work but just with very little electricity. So it would have to be as thin as a shadow, meaning two dimensional instead of three dimensional to not conduct electricity.
How quickly will a car radio drain the battery?
I've just installed a new car radio, and even though it is switched off (and the face has been removed) with the rest of the car completely off, the battery is flat 2 days later. You have a dead cell in the battery or something else is on draining the battery. A radio that is not on will not drain a battery in 2 days or even 2 weeks.

How do you know if the car alarm remote battery is flat?
If you know for sure that the alarm is functioning correctly, but the key-fob doesn't operate - either the fob is faulty or the battery is flat. Replace the battery - if the fob operates the alarm, then the battery was flat. If the alarm still doesn't operate, then the fob is faulty. You can always test the battery with a multimeter - although you may have to dismantle the remote to get at the battery !
