batteries
In a battery, a chemical reaction takes place which makes the electrons leave the positive terminal, leaving ions, and gather on the negative terminal. This makes a potential difference across the terminals. When sufficient voltage difference builds up between the electrodes, electrons can no longer make the journey across the battery and the

Should Negative on Battery Bank Be tied to Ground?
When you ground the battery bank (negative battery bus ground bonding to ground rod/cold water pipe/etc.) it makes sure that the negative terminal can never get above zero volts. So shorting the negative wiring cannot cause a "short circuit" or over current situation and you only need fuses/breaker in the + leads (DC input to inverter, any 24

Why to disconnect the negative/ground terminal, not positive?
The grounded terminal should be disconnected first to ensure that a battery dead-short does not occur, should the spanner disconnecting the other one contact a nearby grounded metal part. A battery dead-short will result in short circuit currents of the order of hundreds of amperes and heavy sparks.

What is a positive ground on a car battery?
In simple terms, it refers to the connection between the battery and the chassis of the car. If the negative terminal of the battery is connected to the metal frame of the car, then it is a negative ground. Conversely, if the positive terminal is connected to the metal frame, it is a positive ground.
What is a negative ground battery?
This is called negative ground, since the negative side of the battery is grounded to earth. Then engineers discovered that with positive voltage on the copper wires, copper wires age quickly, due to electrolysis. With negative voltage on the wires, in respect to earth, (called positive ground) the copper is protected from corrosion.
Is it safe to touch a battery positive terminal?
As long as you don’t touch the battery positive terminal at the same time you will be OK and since the battery positive terminal usually has a red cover on it there is little risk. Once the battery negative is disconnected, accidentally touching the battery positive to the cars bodywork using a tool is no longer dangerous.
Why should a battery terminal be connected first?
It is simply due to the safety it provides in the connection process. Connecting the negative terminal first before the positive can trigger a big spark or arc through you when the spanner or wrench you’re using to tighten the positive cable gets in contact with a metal surface on the car. Which battery terminal should be disconnected first?
Should a positive battery terminal be disconnected first?
Although disconnecting the positive battery terminal first is possible, this is not wise, as you might damage your vehicle by doing this or even hurt yourself. While undoing the cable lead, you might touch a chassis or other car’s metal parts with a spanner while undoing the cable leads. Why is the negative terminal disconnected first?
Does 'ground' affect a battery?
"ground" has absolutely no relevance to a battery until you connect it to one terminal, in which case it follows that you had better not also connect it to the other.
