Most batteries, not cell phone batteries, have four terminals: two for the positive (“+”) charge and two for the negative (“-”) charge. The positive terminal is usually labeled “red” or “+” and the negative terminal is usually labeled “black” or “-”. Cell phone batteries typically have three terminals. The reason other batteries have four terminals is so they can be connected in either series or parallel circuits.
Anatomy of a Battery - The anatomy of a battery includes a cathode and anode. Learn about the parts and anatomy of a battery at HowStuffWorks.
The elements fit into the individual cells of each battery. Battery Paste: The paste is a lead oxide mixture that creates both lead dioxide and sponge lead. It adheres to the positive and negative battery grids. The battery is an essential part of your vehicle—explore and better understand the parts of an auto battery.
Typically, the terminals are located on either end of the battery. While legacy batteries typically have two terminals (one at the cathode and one at the anode), more recent batteries can have more than ten terminals. Figure 1 shows a battery diagram for an Li-ion battery.
Look closely at the cylinder-shaped battery in the picture. It has two ends: one has a part that sticks out on its top. Next to it, you can see a little plus (+) sign. This is the positive end of the battery, or cathode. The completely flat end of the battery has a minus (−) sign next to it. This is the negative end of a battery, or anode.
Batteries have two terminals because they are designed to create a circuit. The positive terminal is typically marked with a plus sign, and the negative terminal is typically marked with a minus sign. The reason for this is that the battery needs to be able to send an electric current through the circuit in order to power it.

At this point, it''s worth noting depth of discharge. This refers to the amount of battery capacity you can use safely. For example, if a 12kWh battery has an 80% depth of discharge, this means you can safely use 9.6kWh. You should never use your battery beyond its depth of discharge as this can cause permanent damage.
