Just had 74,000M service. Garage warned battery needs replacing soon. Amazingly, three days later (despite NO previous warning) had a flat battery (despite long runs too!):evil: . Being inquisitive retired engineer I checked volts after jump start and running for 35 mins. Result? 12.40, which seems fairly healthy. Then checked residual current drain with all normal things sweitched off. I found a constant drain of 160mA. Is this normal?? (Bought a new battery anyway.....)
