But you should also check Wire Size Calculator
(checking for voltage drop over length at various gauges will help your battery live longer - use 13.8V rather than 12, because most voltage regulators lately are set at at least that point. I also used 5% voltage drop and am still good because the length of my cable is shorter than the max length in the calculator, and my charging voltage/regulator set point is 14.5VDC - that's the published spec, but I measure a few tenths of a volt higher. That might mean that the battery is de-sulfating and absorbing energy still. I should pop it open and check the electrolyte level in it)
As best I can recall, this battery is about 4 years old, give or take about 6 months - around the time that most batteries need replacing in cars. If I have to put a new one in in the future, I'll be sure to compare the date code to the date of replacement
