12 volt
on my old 1.2 clio the battery light came on as there was fault with the alternator and it needed replacing. As far as i know the battery light comes on when the battery is not charging or there is a fault with the battery.

On my clio there is a vertical post besides the battery. This will actually undo if you place a socket on top. Approx 7mm socket will remove the post and therefore clamp at bottom.

hi you havent said what year your clio is but if it is pre 1998 mk3 it has a long 7mm bolt between the battery and relay box assenger side of battery good luck. On 1998+ Clio 2s, there is a bolt between the battery and the electrics box. It's on the passenger side too. To unscrew the bolt, you'll need a 13mm spanner, although it's sort of blocked by the battery, so ideally you'll have a wrench with a screwdriver handle so you can get down there easier. Hooray!
HI, I have a clio 172, i have recently had that problem with my car, what would be worth doing is actually changing the battery in the key fob, if the battery is week it will not recognise the key and therefore not start. It will crank but not fully start, I changed my battery in the key fob and started first time after!
