The terminals' negative terminals have rings of raised dots too, so you won't confuse the negative terminals when you connect negative cables. The positive terminals' rings of raised dots are larger than their negative counterpart's, so it's easier to connect the positive cables to the terminals' positive terminals. The negative terminals' rings of raised dots are smaller than their positive counterpart's, so it's easier to connect the negative cables to the terminals' negative terminals. The positive terminals' ring of raised dots keep the battery from touching the terminals, so the battery won't short out its terminals. The negative terminals' ring of raised dots keep the battery from touching the terminals, so the battery won't short out its terminals. The terminals' rings of raised dots also make the terminals easier to grip, and they give you a better feel for whether the cables are firmly connected. The terminals' raised dots and rings of raised dots are large enough to be easy to see, and they make a positive connection with the battery. The terminals' covers keep the cables from rubbing against the terminals, which will prevent corrosion. The terminals' covers are made of strong, durable plastic, so they're more resistant to cracking and chipping than the covers on other battery terminals. The covers don't scratch or scuff the battery boxes or the batteries. The terminals' covers don't spiral or twist, so they won't lose any contact over time. The terminals' covers are large enough to easily fit over the terminals and the battery cables. The terminals' covers are sturdy and won't fall off or come off by themselves.
