Battery cableis used to power your electrical system and is sized according to the american wire gauge or awg for short specification for electrically conductive cables.
Car battery cable size.
Fine stranded stereo wire makes great battery cable giving the best gage wire for proper battery charge.
Automotive wire and cable.
2 0 awg battery cable 2 feet length with gold plated terminal lugs high conductivity terminal ideal for car boat battery solar battery wiring.
For example flex 16 cable conductor specification.
2ga sgr battery cable 250 spool red 2ga sgr battery cable 250 spool black.
203 0 30 16mm2 110a 8 3mm indicates that the cable has 203 x 0 3mm diameter strands of copper giving a cross sectional area of 16mm 2 the outside diameter of the cable including the insulation is 8 3mm and the current rating is 110amps.
With a highly flexible epdm jacket and paper separator these sgr battery cables meet sae j1127 and the requirements of ul 558 and ul 583.

In summary when selecting the correct size of battery cable you need to take into account the total maximum amperage your electrical system requires the voltage of your system usually 12 volts the total length that your cables need to be and the amount of voltage drop you are willing to accept versus the amount you want to spend.
The fine stranded wire will pass more amperage than course stranded wire that has a lower strand count.
