Another thing to consider is battery cable gauge size. Many of the replacement cables tend to be a smaller gauge wire. Smaller diameter wire size is in essence a restrictor in the amount of voltage that can be passed down the wire - a straw vs a 2" pipe.
Go with the largest gauge you can fit. Larger gauge cables will cost more, but will give you all of the voltage needed.
Here is what I found:
What Gauge or Size Cable do I need?
- .333" Diameter
6 Gauge works for accessory leads and most stock alternators. Battery cables for small engines (like ATVs and sub-compacts). Some stock golf cart wiring.
- .360" Dia.
4 gauge wire makes great accessory leads and alternator wiring (up to about 180A). Many cars use this as battery cable. Some electric ATVs use #4
for the battery banks. It also makes very good automotive booster cables.
- .440" Dia.
2 gauge wire is recommended for 4 cylinder and small 6 cylinder automotive engines, hi-power accessories (like winches, power converters) and alternators over 180A.
0 or 1/0 Gauge
- .520" Dia.
1/0 makes great battery cable for large or hi-performance 6 cylinder engines and stock V8s.
- .570" Dia.
Use 2/0 battery cables for hard to crank engines (like high compression, big blocks, or diesel engines), electric vehicle battery banks (depending on controller amperage), and large RV power converters house batteries.
3/0 and 4/0
are for very large marine or heavy equipment engines and high power alternative energy battery banks.
For very long cables (for example 15-foot long battery cables to relocate your battery) go one size larger.
Going up a size or 2 is worth it in the long run. The manufacturers make stock battery cables as small as possible but still get the job done. Use cables larger than the factory because they will work better and last longer.
