3X Conductive Zinc Car Battery Terminal

Conductivity matters.

Every time you turn the key to start your vehicle, it pulls large amounts of electricity from the battery in order to power all of the vehicle's systems at once. Zinc battery terminals are 3.6x as conductive as lead battery terminals, providing for an easier route for power to get where it needs to be going.

RoHS Compliant Car Battery Terminal Connector

Environmentally friendly.

All of our battery terminals comply with RoHS (Restriction of Hazardous Substances) standards. Lead-free zinc battery terminals do not carry any harmful heavy metals, allowing for ease of use, re-use, and disposal.

Choosing The Right Terminal

Understanding which battery terminal best fits your application.

Before you purchase a battery terminal, double check your vehicle's battery set-up. A common vehicle battery variant is a side post battery (pictured above). The TZ510CS is a side post terminal that attaches directly to a side post battery.

Zinc Vs. Lead

The difference is clear.

Zinc plated car and boat battery terminals are not only safer to handle and dispose of, but they provide for superior connection and conductivity. As an added bonus, zinc oxidizes at a much slower rate than lead, providing for a rust and corrosion resistant battery terminal connection.


The right fit.

More often than not, dealing with components under the hood can lead to tight fits, even with battery terminals and battery posts. Double check the measurements to make sure that this terminal will fit your application.
