Am not the only 1 that was going to post a query on this aspect of cold starts. This morning, just before leaving for appt at The Christie (so, didn't need this to happen), went to start car and battery wasn't flat, as there was no 'click, click, click'.
It was certainly trying and had some juice, just not enough to start engine (admittedly, car had only done very short journeys for previous 6 or 7 days-less than 1/4 mile/stop and start-and last night was particularly cold, -4! It was not a case of having left any lights on etc. Managed to obtain help from pitch across from whre we live where we purchased car and this solved todays problem and further journeys today.
However, i am thinkng of the future, and since battery not totally dead, just needing a boost, what are peoples opinions of items such as portable car jump starter/power bank-these are the smaller versions about size of ipad and not the large heavy type about size and weight of actual car battery! Plenty of reviews say these smaller lighter types are strong/powerful enough to start car from dead battery & sems way to go with todays battery technology.
Interested in further views and opinions. Many thanks.
