A few weeks ago I was coming to the car in the morning and finding it dead, enough power to deactivate the alarm but only the drivers door would unlock using the key. I would put it on charge and it would be alright for a few days, when it would happen again. It started to happen increasingly often and, when it happened the morning after I had put the battery on charge, I assumed that the battery (the original one) was faulty.

So I had a new battery fitted about 2 weeks ago and all seemed well, until this morning. This morning the whole car was dead, alarm still active and LED flashing it's normal rhythym, the alarm would not deactivate from either fob. So I opened the driver's door, popped the bonnet and searched around in vain for somewhere to use the key under the bonnet to deactivate the alarm while it wailed away. What was odd this morning was that when I put the battery charger on it would not start charging (it's a Halfords one which doesn't provide power to the clips until it detects a circuit has been made). This was only a few hours after I had successfully opened and then locked the car using the fob.

Assuming the new battery is not defective, then it seems logical that there is an electrical fault somewhere. It's odd that the length of time between charging the battery and finding it dead seems to vary, sometime it's a week sometimes the next day. Could something in the electrical system be causing a problem seemingly at random in this way? Could an earthing problem cause something like this, I am fairly weak on electrics?

Anyone had a similar experience?
