Dead battery tonight, very convenient!!!!

Well it was near dead after 4 days of sitting, the engine barely turned over.

So hooked my jump pack on it and off she went..

Did around 55mi round trip and came home, upon hooking the multimeter to her it seems she is running at 14.11 which is good even with the headlights on

However after turning her off it dropped from 14.11 straight to 12.6 volts, and it started to drop quick quite quickly..

I would assume there would of been some kind of surface charge on the battery after a run, which it didn't seem to show...

Hankook MF31-1000 only a year old!!!

Grr

After leaving her for a 2 minutes she went to sleep so nothing is keeping her awake...

12.6V is a fully charged battery.

If you got it from battery megastore, it's got a 4 year warranty (see para 17 here https://www.batterymegastore.co.uk/terms-and-conditions/). Charge it fully and see what it drops to after it has been left but if it drops below 10.6V it is fubar.
