Nissan 370 Battery

OPTIMA Batteries
Elkhart Lake, WI

OPTIMA Batteries makes two different batteries that are direct-fit upgrades for the Nissan 370Z and both are Group 35 batteries. Our Group 35 REDTOP battery offers plenty of cranking amps for the 370Z's 3.7-liter V6 and is great for daily-driven cars or Nissans that don't have significant electrical accessories. What would be considered "significant" electrical accessories? It's not like anyone is going to be installing a winch on the front of a 370Z, but aftermarket stereo systems and aftermarket car alarms can have significant key-off loads or parasitic draws.

That means some of these systems can draw a significant amount of energy from a car battery, even when the car isn't running. For example, if a car alarm has a parasitic draw of 80 milliamps, that means it will draw 1.92 amps per day (.080 x 24 hours). Since our Group 35 REDTOP is a 44Ah battery, that means that battery will be completely discharged in just under 23 days- far shorter than most COVID-19 social distancing directives. That assumes the battery is fully-charged when the car is parked (most are not) and doesn't take into account factors like heat, that can accelerate this process or any other parasitic draws that the car might have from the factory, which the 370Z likely has. If we added in a very conservative 30-milliamp draw from the factory for a total of 110 milliamps, that translates to 2.64 amps per day and less than 17 days before the battery is completely discharged.

So what do you do if your 370Z has a significant electrical draw? The best thing you can do is to keep your battery fully-charged whenever possible. OPTIMA offers chargers and maintainers that can do just that and if you purchase a new OPTIMA battery from us and a Digital 1200 charger at the same time, we'll extend your free-replacement battery warranty by a full year. If you know you'll be routinely running your battery down by parking it at work with the alarm on, running an aftermarket stereo with the engine off or maybe you are going to hook up a winch, then our D35 YELLOWTOP battery will be a better choice. Our YELLOWTOP batteries are designed and warrantied for deep-cycle use, so in addition to offering more reserve capacity (48Ah), our D35 YELLOWTOP is better-suited for applications where they may be cycled more deeply or more often.
