I was charging a car battery in situ using my bog-standard B&Q

Had you un-coiled the extension reel?

It shouldn't make any difference - they are rated coiled and uncoiled but I
don't recall seeing a coiled rating that wouldn't drive a battery charger!
Call it 100W load, that's ~400mA.

It sounds like it was in the car and got hot in the sun.
