The battery failed (totally) in mine a couple of years ago to the extent that the electric steering lock would not work, so it was stuck in Park. The RAC guy turned up, applied his jump pack and there was only enough juice in it to allow us to unlock the transmission, get it into neutral and push it out of the garage so it could be jump-started from his van.

There's not much power in the £50 consumer ones - they offer a bit of boost but will not help if the battery is properly dead.

I've got one of those jump packs which i have used successfully on a number of cars over the years including a 300tdi Discovery in the middle of winter.

I bought a cheap one off of the bay - about £30. It started my 4.4 a couple of times when the battery was low (from leaving interior lights on etc) and also started it from completely flat once (2 days of interior light on!) But was slow to turn over, if it had been winter I doubt it would have worked.

My Dad bought me a cheapish Batt pack but it is a bit crappy and no good for my Rangey, it is good for providing power through a cigerette lighter socket or using the built in air pump but thats about it.

how about one of those solar battery charger things you can leave on the dash and it'll keep your existing battery topped up..

Use one every time I go to work, leave the car for 3 months and it starts first press of the starter button - even after sitting on the drive from October to February last winter the battery was good. They don't need sunshine either as my car spent weeks under a covering of snow and according to reports my father could see the LED that indicates that the battery is charging was still visible winking away. I also plug it into the boot socket which IIRC remains live even when the ignition is off 2018 Mini Countryman Cooper S E All4 PHEV in Melting Silver - it’s whisper quiet in EV and polluter modes |

+1 for taking out the bulbs. If a door is left open, the interior lights automatically switch off after 45 (??) mins to preserve the battery.
Set the steering wheel as far back into the dashboard as it will go. Then move your seat forwards to the appropriate position and set the seat memory. The steering wheel won't move then. You will end up with a bit less knee room (I'm 6'1" and it's no problem) but it will save you lunching the steering wheel motor as they do have an annoying tendency to break. 2021 3.0 P400 Vogue 2012 4.4 TDV8 Westminster - gone! 2007 3.6 TDV8 Vogue - gone! 2003 V8 HSE (LPG) - gone! 2018 F-Pace 25t Portfolio 1974 LR Series III Lightweight FFR 2014 BMW 640i Gran Coupe |
