• Astra 1.6 2011 - False electric hand brake warnings 16 Aug 2022 (Forum)
  Hi, After a recent flat battery i am getting false "take handbrake off" warnings when travelling at low speeds. I'm assuming this is a symptom of the battery discharging? Does it need a scanner to clear codes or re-set handbrake sensor?

• Any - Analysis of Rechargeable Battery - Electric Cars 16 Jul 2014 (Forum)
  The nominal efficiency of the process is further diminished in the use of mains electricity in our homes to charge up the 400 volt 5/10/22/24 kWh 'battery' in an electric (EV) or in a petrol-electric hybrid (PEHV) car or motorcycle. Typically between 30 and 50% more electricity than is actually stored as usable energy in the battery, has to be 'drawn from the mains' in the battery charging process.

Plip has lock/unlock and deadlock buttons - the car locks/unlocks fine with the remote, and the battery still powers lights, windows etc. (I've also swapped a second known good battery and tried that - no different.

• Vauxhall Astra Mk 5 2.0 Petrol - Misfire after 30 seconds. 12 May 2020 (Forum)
  I am a competent engineer so able to check things but have absolutely no knowledge of engines. I have the following thoughts but any advice would be most welcome. A) As the battery has been flattened could it be the battery is not good enough for the spark to be ok on each cylinder causing a misfire? I thought once a car was started it should run which would rule out the battery?
