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.

Wire the batteries in "series". Place jumper from neg (-) terminal to the pos (+) terminal on the other battery. You will have 24V across the remaining terminals.

How do you turn off a check engine light?
Take the positive terminal off the battery for a few minutes. Then put it back on, This should reset the computer. You can also take the neg terminal off and get the same results.

unscrew the bolts on each terminal. remove the negative first then the positive. When replacing batt, place the neg first then pos.
How do i charge a battery on a Honda rebel motorcycle?
As with any battery, you need a battery charger. They are not too expensive, just make sure that it not only charges at 10 amps, but also at 2 amps. Remove the neg. and pos. cable from the battery, and put the red wire to the positive terminal, and the black wire to the neg. terminal at a charge rate of 2 amps. The charger will tell you when the cycle is complete. May take a day or 2 if the battery is dead. Also make sure the water level is at the top line in the battery. Use only distilled water to top up.
