usually it should, but if it doesn't show then the flat side is negative and the tip is positive,
On an automotive battery the larger post is positive +.
On the battery is marked - or +. The red cable is positive and the black is negative.
On the battery. Normally marked + and - but the round tapered post that is bigger diameter is positive. Some newer cars have a positive and negative post remote from the battery for jump starting because battery is not easily accessed.
positive to positive
In a 1993 Mercury Villager, the positive cable is typically connected to the positive terminal of the battery, which is usually marked with a "+" symbol and often has a red cover. The negative cable connects to the negative terminal, marked with a "-" symbol, and is usually black. To locate these cables, open the hood and look for the battery, which is usually situated in the front engine compartment. Always ensure safety by disconnecting the negative cable first when working on the battery.
Positive to positive, negative to negative if you are asking about installing one battery in a vehicle.
To recharge the battery on a 2014 Dodge Avenger, connect the positive (red) cable clamp to the positive terminal of the battery, which is marked with a "+" symbol. Then attach the other end of the positive cable to the positive terminal of the charger. Next, connect the negative (black) cable clamp to the negative terminal of the battery, marked with a "-" symbol, and the other end to a metal ground point on the vehicle or the negative terminal of the charger. Always ensure the vehicle is turned off before connecting the cables.
Energy flows from the negative terminal to the positive terminal of a battery.

What happens when you inadvertently crossed the positive battery terminal from a negative to a positive and a positive to a negative.?Read more: What_happens_when_you_inadvertanly_crossed_the_positive_battery_terminal_from_a_negative_to_a_positive_and_a_positive_to_a_negative.
A battery has two terminals—positive and negative—because they facilitate the flow of electric current. The positive terminal, often marked with a "+" sign, attracts electrons, while the negative terminal, marked with a "-", releases them. This difference in charge creates an electric potential difference, allowing electrons to flow from the negative terminal to the positive terminal when the circuit is closed, thus providing electrical energy for devices.
To hook up jumper cables, attach one cable from the negative post on one battery to the negative post on the other battery. (These usually are marked "-" and have a blacl cable attached to them.) Attach the other jumper cable from the positive post on one battery to the positive post on the other battery. (These usually are marked "+" and have a red cable attached to them.)
