I am thinking of buying a heavy duty Jump starter. I already have a 300Amp starter but I noticed that if battery goes a bit too flat then it does not work. I guess Amps are the main thing when you chose these things. Am I right? Would 900Amp be strong enough to start a car when battery is completely dead? Any suggestions would be appreciated.

I think I'd spend the money on a decent battery rather than on something that "aids" a poor one. But you may have a good reason for this purchase. And, yes...a bigger output will give better results.

I have and always do purchase decent battery. But in cold winter these things tend to go down when car is not used regularly and I am thinking just for the backup purpose otherwise I also have RAC membership.
Another suggestion would be to keep the battery "topped up" with a mains trickle-charger (if garaged).....or a solar-powered one, if the car is outside. Both available in Maplins.
The condition of charge determins how much you are taking out of it, if you are doing very short trips with the radio, wipers, de-mister, lights onyou will not put back what you have taken out, this excludes the first thing of starting.
Remember the old days when your car wouldn't start? You'd just get it rolling down a slight incline and then jump in and, invariably, it would start...Now that was 'jump starting'.
Do you go back as far as the crank handle Stewey?
I always thought that the guy who invented the wheel was intelligent; however, when that other genius invented the extra three, things were a lot easier...The crank? It came much later, TWR.
Stewey - what about the guy who invented the extra two , for a three wheeler ? - Dont leave him out
Stewey, "Now that was 'jump starting'" no that was bump starting not jump starting, a bit different. I have bump and jump started many cars over the years, getting to old for all that pushing these days lol. I used to bump start my mini by pushing it a long the flat and jumping in as it was moving. At least my old Land Rover has a starting handle :-)
Bazile, he's the guy who went on to invent the 'Edsel': never amounted to much:)
RATTER15, I've never heard it called 'bump starting'. Must be a different side of the pond type of thing.
Maybe Stewey, Jump starting is with cables and bump starting is by running the car down hill here in UK.
I just typed 'bump starting a car' into Google (Canada/US), and it said "Did you mean jump starting a car"; so, yes, it's a pond thing.
That's why this site is so interesting: we seem to learn something new every day.
I'd have thought that your existing pack would do the job for the average car provided that when you connect it you put the positive connector to the + on the battery and the earth/ground to a suitable point on the car rather than the negative post of the battery.
You're trying to start the car rather than charge or top up the battery.
