Is the anode side of a batteries the positive side or the negative side?

" Anode " is generally refer to POSITIVE. Cathode generally refer to NEGATIVE. But these terms are use for different applications ( For example: you wouldn't refer to the POSITIVE side of a battery as ANODE or NEGATIVE side as CATHODE, it commonly refer as positive or negative when you are dealing with battery application etc. )


How do manufacturers of batteries that use batteries make sure you do not install the batteries incorrectly?

They put a +(positive) and -(negative) on each side. The + matches with a - and vice versa.


What are the negative and positive aspects of battery technology?

Battery technology has both negative and positive aspects. On the negative side, batteries can be expensive, have limited lifespan, and can be harmful to the environment if not disposed of properly. On the positive side, batteries provide portable power, are rechargeable, and can store energy from renewable sources like solar and wind power.


How do you connect two twelve volt batteries for a truck?

Assuming the truck has a 12 volt system, connect the batteries in parallel, that is positive to positive and negative to negative.


How do you know positive and negative terminals?

Look for a + by the positive terminal and a - by the negative terminal, or red for positive, black for negative. Some batteries have the positive terminal protruding and the negative terminal flat. Or you can get a meter that will tell you which is which,


Can you charge two 6v batteries in a series with a 12v charger and which posts do you connect the charger to?

Yes you can. Connect the chargers positive lead to the positive of one battery, then the negative side of that battery to the positive side of the other battery, then connect the negative lead of the charger to the negative of the second battery. Double check all your connections and turn on the charger.


Why does one end of the battery have a negative symbol on it?

because batteries works on the principle of electron charge and an electron can have either a more positive or negative charge but the electron wants to have an equal amount of pos. and neg. charge so when batteries are simply they pull the positive charge to one side and negative to the other side and when they come together with a conductor(wire) it creates a current which does the "work" for you. The voltage of the battery pretty much lets you know how strongly the battery wants to create equality between each side thus more current.


What is positive about batteries?

How do you connect two batteries to work as one?

Type your answer here... To use two batteries as a single power source, you have to connect the positive to the negative and the remaining negative to ground. The remaining positive goes to the red positive cable. The batteries are now in a series circuit. If you use two 6 volt batteries the total voltage is 12 volts. If you use 2 12 volt batteries the total voltage is 24 volts. If you hook the batteries both negative to negative and positive to positive you have made a parallel circuit. Batteries in a parallel circuit cancel each other out. Two 6 volt batteries in parallel have a total voltage of 0 volts. klb


How can you tell what side is negative and what side is positive?

Is it possible to jump-start a car battery with a positive-negative connection?

No, it is not possible to jump-start a car battery with a positive-negative connection. Jump-starting a car requires connecting the positive terminals of both batteries and the negative terminals of both batteries. Connecting positive to negative directly can cause damage to the electrical system.


Is it red to positive and black to negative on car batteries?
