1. SAE Certified Insulation
The most important characteristic of good marine battery cable is that the insulation they’re made with needs to be SAE certified. The SAE (an abbreviation for the Society of Automotive Engineers) maintains well-researched standards for marine cable insulation that allow for certification of products under their standards. SAE certified cables are a must for any project.

2. Tinned Copper Strands
Only slightly less vital to the continued function of marine battery cable is tinned copper strands being used within the cables. Tinned copper refers to a process by which copper strands that make up https://capitalmaniacs.com/cables are coated in a small amount of tin in order to increase their resistance to corrosion from moisture. Tinned copper is the standard for marine cable use, and as a result, it’s a core characteristic to keep an eye out for.

3. High Strand Count
A high strand count refers to the number of individual copper strands inside a cable. The higher the strand count a marine battery cable is, the more flexible and conductive that cable will be. This characteristic is particularly important to marine electrical systems because of the tight spaces most marine systems impose. Tight spaces on marine vessels are easier to work with if your cable is flexible. In addition, because marine insulation is much less flexible than other insulation types, a high strand count can help counteract this downside.

4. Clear Coloration
In electrical systems, a lot of negative results can come from misconnecting your cables. One very easy way to make this less likely is to label your cables and ensure they are different colors. You’re less likely to connect a cable to the wrong spot if you can tell you’re holding two different cables based on their color.
