charging a car battery

I've not been out in the car for about 10 days! and it's back to work on Monday.

I found my grandads old heath-robinson style battery charger (looks about 40 yrs old!) he used to use it all the time when he came back from long holidays.

Anyhow I wonder if its worth charging the car, and would be grateful for any advice.

I have a relatively new battery (maybe 12 months old - a Unipart GBA 3202), and looking in the Haynes book it says some batteries are maintenance free, I thought that meant I should leave it alone, but don't know if it applies to this battery model.

I am not at all technically minded and just wonder whether I should trickle charge the battery? Or am i better leaving alone. It's not flat, lights come on, and I'm sure it will start. I have a fiat (and don't have the red key). I don't want to balls up anything like immobilisers etc. Things are more complicated now than in my grandads day I guess. :rolleyes: I'm leaning more towards just leaving it alone, but I want to take any sensible measures I can before I get the car out next week, I don't want any problems with it if I get caught in a blizzard.


Thanks in advance for any suggestions.
