picasso starting in morning

[stevesofas]

Hi, just purchased a 54 plate Picasso 2hdi. The seller claimed the battery was poor.
Every morning it fails to start first turn of the key and sounds as if the battery is going dead, but it always starts 2nd turn of the key each time.
Its fine then rest of the day. I am thinking towards a slow starter? Any help would be appreciated.

Many thanks

Steve

If battery is old might be that , 75 amp hours is good more is better, glow plugs , ngk rubbish bosch better, charge the battery any thing over 5 yr old will need good charge. And yes if the starter is old it will turn slower , changed my one and it started faster
