Battery

[agithegreat]

I came to open my car yesterday and the battery was flat.... Car wouldnt even unlock, had to use key. I recharged it and took it out for about an hour, then this morning voltage down to about 11v again... Clio 1.2 dynamique, only has a wimpish 36ah battery. Alternator is 70ah, should i get a renault dealer to change the battery for me of should i just go and get one myself??? I was thinking about a 50ah one....
What do you guys think??

Test it yourself, put the voltmeter on the batter when the engines running if its working correctly i think you want about 13.5 - 14.8ish Too high or low means its probably your alternator
