No, the battery terminal should be able to handle as much electrical current as the vehicle should ever use, WITHOUT heating up. Clean or replace any battery terminal that is getting hot.

What could cause intermittent starting problems with a 1991 Mazda Protege?
A bad battery terminal(s) connection, bad ground, bad ignition switch, bad starter.
Dodge caravan 2000 wont start it goes yang yang yang when you turn the key but it wont start i found that the positive battery terminal is a little fried could it be that key turns wants to start?
no that not it
How do you troubleshoot a Ford F-250 6.0 diesel engine starting problem when the batteries read a sitting 12.58 volt but the engine will not turn over?
Quite probably the Starter is defective OR the positive lead from the Battery is corroded internally. Check the Terminal Connections as corrosion WILL INTERRUPT STARTER. Could be the Starter Solenoid which on many Models is replaceable.Check also the Engine Ground (different from the Battery Ground) as a incomplete circuit (Open) will not function. Some Engines have 2+ Ground points.Check Starting Circuit/System Fuses and/or Relays.You could just have a dead Battery regardless of the charge shown as there could be a Dead Cell and when Engine cranked, Battery defects.Ask away if none of these ideas provide a positive result.CHEERS!!
Why would a car just click when trying to start other than the cause of a bad battery?
A bad starter. A loose connection @ the terminal ends-the battery cables-the starter solonoid-IF IT has Rubber covers around the battery ends corrosion from battery acid could cause it.EVEN a bad ground on the engine from the battery 2 the frame.(battery cables) The battery cable ends could be corroded and should be cleaned. The next step would be to check the starter selenoid and then the starter.
Car will not start unless the battery is jumped changed battery and alternator doing same thing pull positive cable off battery car dies what could be wrong with the 1992 eagle talon?
If the battery and alternator are both good, Test them to be sure, then you need to take a multimeter and verify that the power from the alternator is actually reaching the battery. It could be a simple wiring problem
What would happen to a dry cell or battery if the positive and negative terminal were shorted?
It could blow up the battery.
What color is the positive terminal on a car battery?
The post is just lead, gray color. The cable is sometimes colored red. The battery could also have a "+" symbol to mark positive.
What happens when you put the negative terminal on the positive terminal and the positive terminal on the negative terminal on a Mercedes-Benz s500?
It could cause the battery to explode. It can also destroy some of the electronics in the vehicle. In other words this would be a very expensive mistake.
Why most car bodies are attached to the negative terminal of the battery?
The DC electrical system of the car requires a positive and negative electrical conductors for each electrical device. Taking the example of a single lightbulb powered by the car battery, this could require a wire leading from the positive terminal of the battery to one terminal on the lightbulb and a second (return) wire leading from the other terminal on the lightbulb back to the negative terminal on the battery. Two wires are required - a positive and negative. To reduce the quantity of wires required, the negative "wire" is actually the car body. Hence there is a positive wire leading from the positive terminal of the battery to the positive terminal of each electrical device on the car and the negative terminal of each electrical device on the car is connected to the car body (a metal conductor). The body of the car is then connected to the negative terminal of the battery, completing the circuit. There are virtually no return wires. This works as cars use a low voltage (12 V). If they used a higher voltage, this system could result in electric shock from touching the car body.
Is the red battery cable always positive?
In most cases yes but not all. The battery cable could have been replaced and the original color may have not been followed. Normally we do think of red being positive and black being negative. It is possible to make a black cable work on a positive battery terminal although it needs the end opened up to do it. The positive terminal is always the LARGEST one on the battery itself, the negative being the smaller. This is true on batteries with terminals or posts on the top. If the battery uses a side mount for the cables, each terminal should be marked + / -
What could be draining the battery on a 1970 firebird?
It could be lights on in the trunk or a short someplace, your best bet would be to touch positive cable to the battery and if you get a spark something is drawing power from the battery, pull one fuse at a time and recheck the spark at the battery and when you have a fuse pulled and it finally doesn't spark when you touch the positive cable to the battery terminal you have found the circuit that your problem is in.
How do you fix the red positive battery wire if it has broken off?
The positive battery cable runs from your battery to your starter and is pretty easy to replace(Depending on vehicle). Hopefully if the positive isn't attached then the negative cable has been removed as well. Follow your positive cable from your battery down through your engine bay and it will lead you to your starter - this could be at the front of your engine block or at the rear underneath. Then all you have to do is replace it, making sure you connect it to the starter first then the battery. If it's just the battery terminal, the connection that actually hooks into the battery then all you have to do is un srew the nuts on each side of the terminal and replace it with a new one. Then reconnect it to the battery positive first then negative. duct tape it
How can you determine positive and negative to hook up car battery?
Answer 1 - Automotive Battery Terminal Polarity DeterminationDepending on the brand and model of battery, there could be one or more ways to determine polarity of the terminals. Some batteries may have only one identifier method, while another battery may have a different identification method, and some batteries may 2 or more symbols embossed into/onto the battery top next to each of the terminals. Here are the battery terminal identifiers I have seen over many years:A plus symbol [+] embossed into the battery top next to the positive terminal,A negative symbol [-] embossed into the battery top next to the negative terminal,An abbreviation [POS] for the word positive embossed into the battery top next to the positive terminal,An abbreviation [NEG] for the word negative embossed into the battery top next to the negative terminal.And on some batteries, although they MAY look the same, the diameter of the positive and negative terminals will be different, with the positive terminal being just barely / slightly larger in diameter than the negative terminal.A DC voltmeter can be used to determine terminal polarity.Answer 2 - Battery Cable Polarity DeterminationOn some cars a red cable denotes positive or the terminal has + or pos stamped into it. If you are presented with two cables of the same colour, the one connected directly to the car body is usually the negative cable, and the cable that goes to the fuses is the positive. BEWARE vehicles manufactured before 1970 may have reversed polarity, with the positive cable going to the body and the negative going to the fuses.
What could cause intermittent starting problems with a 1991 Mazda Protege?
A bad battery terminal(s) connection, bad ground, bad ignition switch, bad starter.
Why should a car battery's positive terminal be connected first for charging?
Batteries vent Hydrogen gas. You should always connect the positive battery cable first to avoid a spark at the battery that could cause the Hydrogen to explode. The negative cable should never be connected to the battery negative post. It should be connected to another ground area on the engine.
Where do you find the reset button or switch on a 2001 Cougar I found it for cars that were older need 2001 Cougar?
Would like to help if I knew what you were trying to reset. Disconnect the NEGGATIVE battery terminal first then the the positive once they are completely disconnected let them touch each other and then put your positive terminal on first then negative failure to do this could result in a ecu failure or even destroy it costly repair DISCONNECT THE NEGATIVE FIRST AND RECONNECT IT LAST!!!!!
What does the neg battery terminal do?
A battery has two ends -- a positive terminal (cathode) and a negative terminal (anode). If you connect the two terminals with wire, a circuit is formed. Electrons will flow through the wire and a current of electricity is produced. Inside the battery, a reaction between chemicals take place. But the reaction takes place only if there is a flow of electrons. Batteries can be stored for a long time and still work because the chemical process doesn't start until the electrons flow from the negative to the positive terminals through a circuit. we take some pairs of the Cohomer Battery Terminals to test and check the result, and you can also browse the Chomer dot com website, to choose the right battery terminals to test for yourself.Electrons are negatively charged, so they will be attracted to the positive end of a battery and repelled by the negative end. When the battery is hooked up to a device that lets the electrons flow through it, they flow from negative (anode) to positive (cathode) terminal.The whole point of a battery is to maintain a voltage (electric potential) difference between two points (i.e. the positive and negative terminals of the battery). Voltage is a strictly relative quantity. The only thing that matters in the real world is voltage differences. Usually we will pick some point to define as 0 Volts (also known as ground) so that we can pretend absolute voltages exist: if some point is 10 Volts above ground, we just say it is at 10 Volts.If you have a 9 Volt battery, for instance, there is no specified reference voltage (ground). The 9 Volts refers to the voltage difference between the “positive terminal” and the “negative terminal.” If we define the potential of the negative terminal to be ground (or connect the negative terminal at a point in a circuit we have already specified as ground), we could simply call the positive terminal the 9 Volt terminal. We could easily define our reference voltage such that the “negative” terminal is really the “more negative” terminal, and the “positive” terminal is really the “less negative” terminal, but this wouldn’t be particularly helpful.A battery allows us to maintain some constant voltage between it’s terminals. Since (conventional) current flows from higher voltage to lower voltage in a circuit, if we connect a circuit across the terminals, current will flow. This is the function of battery. A battery where both terminals are at the same voltage is know as a completely dead battery.
