Modern car alarms rinse the battery so it means you can't really save them these days :(

You jump-started, got it running, drove a mile, stopped, and then immediately tried to start it again and it wouldn't?
DON'T buy a battery charger then! Your battery is DEAD. Deceased. It has shuffled off this mortal coil, ... etc
Edit: Just get a mate to drive you to buy a new battery. (Or use a bike, if you're sure you can stop the acid spilling!). New lead-acid batteries are stored dry. When the battery-seller adds the acid, the battery is in its 'charged' state and ready to go. No need for a charger. (If I remember correctly).
When batteries get old, sludge builds up and short-circuits the plates together. Once that happens the battery is no good whatsoever. No amount of charging will bring it back to life.

I'm expecting this, but feel a charger would be useful anyway as we both have diesel cars (yes I have another car, but the Mrs is out and about in mine since I broke hers)
good battery knowledges there!

Diesel car wouldn't start after holiday. Paid a fortune (penalty joining rates) to AA to come out and start it, persuaded them to STAY around while I drove around a bit to 'recharge the battery'.
Waste of time & money. The battery was deady dead DEAD!
So I got another jump-start from the AA guy (glad I'd told him to wait!) and drove to a battery supplier (a cheapy tyres / exhausts / battery place).
Result: I still had to spend the £60 for the new battery, but only after wasting £75 on AA membership! Don't do what I did! Phone up the battery supplier and they'll be happy to check the right battery's in stock for you. Then just go and get it.

in fact I've done pretty much this thing in the past. Joined the AA on the spot to get them to tell me I needed a new fuse which they didn't carry in stock!

I had a massive argument with my mate at work about me being able to save the battery. I ave it 24 hours on a charger and it didnt work, I gave it 25 mins car to car power and it worked....only to die once I'd turned it off and tried to fire it up again.

then remembered I hadn't plugged the alternator back in. I was too embarrassed to ask them to do it again so waited for a while and then got someone else to push me. He was a hitchhiker and I drove him 20 miles to say thanks!
