Had a strange smell of burning plastic ( only mild) during the last few outings. Seemed to be be coming from the cabin as no smell when under bonnet.
Anyway, went to start it after a run - had 2 seconds of starter motor click then nothing. Totally no power not even the radio.
Tried to jump start it off the terminals ( no battery involved) slow crank no fuel pump buzz.
Put terminals back on then it started . Battery still showing 12.5v on the multimeter.
Could it be the battery? Puzzled by it now appearing to be ok?
Battery Bosch 9 years old. Summer use and winter trickle charge.
4.3 precast.( No 100 amp fuse)
Just thought I’d ask in case it could be something else?

Thanks for the advice.
Fitted a new battery after checking the wiring ( including the earth points under the whale tail). All are good.
It didn’t do it again since the no starting/ dead battery incident. Hoping it’s a weird battery fault due to its age?
Will check the engine mount/ heat shield to make sure but there wasn’t any smell under the bonnet, just in the cabin.

Just to update:
Changed the battery for a new one. No problems since, so fingers crossed.
In fact it’s solved a couple of problems.
The drivers door solenoid would not always work , a couple of weeks before the new battery, now ok.
The car seems to run smoother ( better tick over, not stalling at junctions). Maybe the ECU was Inadvertently being reset , and losing data??
Anyway, just thought I’d update you in case anyone has similar.
