Battery terminal

In recent years, the most common design was the SAE Post, consisting of two lead posts in the shape of truncated cones, positioned on the top of the battery, with slightly different diameters to ensure correct electrical polarity.

L terminals consist of an L-shaped post with a bolt hole through the vertical side.

These are used on some European cars, motorcycles, lawn and garden devices, snowmobiles, and other light-duty vehicles.

These types of battery terminals were designed as a result of environmental directives such as Proposition 65 and RoHS.

Larger external battery packs use a variety of connectors, including the Anderson Powerpole MultiPole series (as used by Tripp Lite), which are color-coded and keyed for specific voltages.
