4 In 1 Jump Starter Halfords 594335. Is It any good? Has Mixed Reviews?

binao

Do I make the jump or get / do something else?

I'm  not using the car so much now which resulted in an almost flat battery after a  week.

It's  a stop start model, so a new battery is about £200.

Petrol cost would accumulate with more frequent unnecessary  running to top up the battery.

Thank you  for all replys.

I bought the advanced lithium battery jump one and it worked well on my partner's mini who's battery had gone flat for being sat too long unused.

If you are able to park on your own property I'd recommend a battery maintainer. There's one in Lidl at the moment for about 12.00 and I've been using one since April on my car. 
Also battery going flat after a week sounds like your battery is possibly on it's way out or you may have excessive current draw on your car.

I wouldn't get the Halfords unit. I've taken a couple apart and they are very cheaply made. Look elsewhere.

No, do not get that - or anything like it. It's basically a normal lead-acid motorcycle battery with a pair of jump leads. Unless you're religious about regularly charging it, and ensuring it stays charged, it will simply be dead when you want to use it.

If you want a jump box, get something like... https://www.ebay.co.uk/itm/174542230079 instead. Far more powerful, far more convenient, far more reliable.

Not suitable for stop/start but great if you're targeted by gangsters apparently!

"Not suitable for stop-start", my furry wrinkly ones.
How does whether there's stop-start software in the ECU make the slightest difference to jump starting a car?

Stop-start cars are normally fitted with AGM batteries, because lead-acid wouldn't last long with the constant charge-discharge required from very frequent starting. If they mean "not suitable for AGM batteries", then I'd like to understand why. Sure, AGM batteries are optimally charged at a slightly different voltage, about 0.2v different to lead acid... But you aren't charging the battery. You're giving a quick boost to a flat one - and if you have a ciggy socket voltmeter plugged in while you use the jump box, you'll see it's actually not very different to the normal resting voltage of a perfectly healthy battery...

FWIW, I've started a mate's 3.0 four-pot diesel LandCruiser from absolutely pancake using my LiIon cheapy.

On the basis that it's cheap - yet it's more expensive than the one I linked to. And they criticise it for being lead-acid, and for lacking several features (like wrong-polarity connection) present on the LiIon...

Buy a battery charger not a jump pack, or does it need a new battery. My car was parked for weeks at a time

and no issues starting it.

Find out why your car battery is going flat after a week first.
Then you don't need to buy anything like that.
A car should be able to be stood for many weeks if not months & still start.

No, not a bit of it. A few weeks is about the most you'll get out of anything vaguely modern before the battery's getting soft.

Just think about all the things consuming power all the time the car's parked - ECU memories, alarm, remote locking receiver, etc etc.
