Can it jumpstart a 3.2l diesel engine?

I’m not a mechanic but the RAC man who came to my rescue and told me to get one said it would start 5l engines. It has started every vehicle I’ve needed it to no problem so far.

I want to return to amazon (uk). all courier firms i have contacted say they do not accept lithium batteries. has anyone found someone who does?

We contacted Amazon and all the couriers they provided could not ship the return. We did our own research and contacted UPS UK and they were extremely helpful on the phone telling us what needed to be done. Their website instructions were clear and easy to follow. They even called to advise their driver was running late. If you ever need to return batteries in devices like this and you're in the UK, try UPS. Hopefully Amazon will take note of this and get their call centres to advise of useable couriers.

How long are the leads on the GB40?

Not very long, about a foot in old money - you can get an extension if you find that they wont reach comfortably.....

Charged & followed instructions (inc. o/r function) failed to start 2.2ltr engine. pack down to 25% power after 4th attempt. is this a product fault?

I have a Mercedes clc 220 diesel. I fully charged the Noco, connected it and it couldn't start my car. It made a very half hearted attempt to start it. Trying to start it completely drained the noco. It claims to do up to 3 litre diesel but this model isn't man enough for the job
