And time to get some real (16'
or longer) jumper cables, too!
Indeed.
I always carry a heavy gauge set of jumper cables that are long enough to reach from the very front of my vehicle all the way to well behind the vehicle
and reach across the width of the other car/truck. That way if the assisting car has its battery on the 'far' side while parked at right angles behind (think laneway or other constrained access location), the cables will still reach.
With long jumper cables they must also be of heavy gauge copper as the electrical losses are higher as length increases, especially with inexpensive thin gauge cables. Long thick jumper cables are heavy.
For winter, it is important that the plastic insulation on the cables remain flexible in low temperatures. These tend to be more expensive.
A modern alternative is to carry a compact high output lithium 'jumper pack'. The better quality packs are not only quite compact but also pack enough output to actually start the engine in cold weather. And do this multiple times. Charge it periodically to ensure it is fully capable when it is needed.
