Good booster cables are a lot like insurance; you want good coverage -- you hope that you'll never need to use it -- but you know it is going to cost you some money.Qualities to look for in booster cables.
- Copper wire for conductivity and flexibility. Four, 6, or 8 gauge stranded cable.
- Clamps made of heavy gauge metal with strong springs.
- Thick rubber insulation. Plastic insulation tends to stiffen and crack in cold temperatures.
- Length of 10 to 12 feet. Longer cables tend to tangle and cause more voltage drop; shorter ones frequently won't reach.
