• Skoda Octavia - Battery Leakage 13 Jan 2013 (Forum)
  Battery Leakage seems to be an ongoing problem with this model - ours is a 55 plate Tdi. Having scanned through a number of internet discussions, I've come to the conclusion that  for someone with very little in the way of a technical brain, the safest option is to invest in a spare battery and keep it in the boot (a tip from an internet sufferer).

• Peugeot 106 Y Reg Battery warning light 24 Apr 2007 (Forum)
  I have a 2001 Peugeot 106 and for some time the battery warning light has been flickering or constantly on whilst driving. I have checked the battery connections which are fine and the battery is not flat. I have checked the alternator belt and this is fine and am aware that it could be the alternator itself.

  The owner told me afterwards that it had been useing distilled water quite a bit in a couple of cells. New battery time £37.73 later and a nice new heavy duty ( Auto ) 4 year warrantee battery. I bet that does not last 11 years. Always nice to help someone.
• Rotten egg smell 16 Nov 2004 (Forum)
  I have recently purchased a Nissan Primera, and shortly after buying it started to notice a smell of rotten eggs. Basically the cause of this was the Alternator overcharging the battery, which started to dry it up and emit this smell. I got the alternator changed, and replaced the battery with one from another working car. The smell dissappered immediately. 2 weeks on, I popped open the bonnet and noticed that the tray holding up the battery, and the rod holding in place the battery, seems to be covered in what looks like dried up battery fluid (white,greyish in colour and flaky) Any ideas of what the cause of this could be, it's baffled me.
