What size are battery posts?
Marine batteries typically have two posts, a 3/8″-16 threaded post for the positive terminal, and a 5/16″-18 threaded post for the negative terminal.
Which battery terminal do you connect first?
“Positive first, then negative. When disconnecting the cables from the old battery, disconnect the negative first, then the positive. Connect the new battery in the reverse order, positive then negative.”
Will any bolt work for battery terminal?
All components of bolt kit are stainless steel to protect against corrosion.
It is recommended that all battery terminals, bolts and cable lugs be coated with an anti-corrosion battery coating for the most protection from battery acid corrosion.
What happens if you disconnect the positive terminal first?
It can fall across either terminal and the car and nothing will happen. If you disconnect the positive terminal first and you drop a spanner, it is possible for it to fall across the positive terminal and any earth on the car, with spectacular and possible dangerous results.
What are the different types of battery terminals?
Automotive battery terminals
The three types are:
SAE Terminals.
SAE is the standard for most automotive vehicles.
JIS Terminals.
The JIS battery terminal is similar to the SAE but smaller.
L Terminals.
L terminals consist of an L-shaped post with a bolt hole through the vertical side.
Marine Battery Terminals.
Will a bigger battery hurt my car?
Most vehicles have limited space for batteries, so in many cases a larger size, from a physical standpoint, may not work. The problem in most cases is that the terminals will contact the hood and short out the battery or the physical dimensions just will not work.
Are positive and negative battery terminals the same size?
【DIMENSION】Battery Cable Connectors with 2.17″ x 1.18″(L*W); Screw Thread Diameter: 10mm/0.39″,Positive Battery Terminal Hole Dia.: 18.5mm/ 0.73″; Negative Battery Terminal Hole Dia.: 17.5mm/ 0.67″ . so the Battery Terminal Connectors negative one is smaller than the positive one.
Which battery post is smaller?
In both the SAE and JIS standards, the positive is the larger post and the negative is smaller.
Which is positive and negative on a battery?
Each battery has two metal terminals.
One is marked positive (+), the other negative (-).
There are also positive and negative cables in the jumper cable set.
The red one is positive (+), the black one is negative (-).
Which battery post is bigger?
In both the SAE and JIS standards, the positive is the larger post and the negative is smaller.

Can I use marine battery terminals in my car?
Yes, if the marine battery has the rated cranking current to start your car on the coldest day, and you can find one that fits your car. In general, though, deep cycle batteries isn’t necessary for cars and offers no advantage given its price premium unless you intend to deep discharge the battery frequently.
Can you use a metal wrench on a car battery?
Using a socket or adjustable wrench, loosen the bolts that are holding the car battery cables on to the car battery terminals. Make sure not to touch the wrench to metal areas, as the metal can ground and cause circuit damage to your vehicle’s electronic system.
Why do you connect the positive terminal first?
Connect positive first, negative having less potential won’t arc. The higher the voltage, the greater the chance of arcing and fusion. On a car if negative first and you are touching any metal part of car, when attaching positive there is possibility of arcing through you. Your body becomes part of the circuit.
What order do you put jump leads on a car?
One end of the red jump lead should be connected to the flat battery’s positive terminal. The lead must not touch any vehicle metal. Attach the red lead’s other end to the boosting battery’s positive terminal. Take the black lead and connect one end to the boosting battery’s negative terminal.
Do you connect ground wire first?

What metal is best for battery terminals?
Brass battery terminals are much harder than either copper or lead, and should be soldered when possible, but they will hold up best in a corrosive environment. Lead battery terminals are easiest for the layman to work with, and can often be installed using just basic tools.
What happens when a battery is connected to a bolt?
Connecting the two terminals of a battery is a bad idea. If done simply through a wire, would cause heavy current to flow through the battery. This current would heat up the battery and reduce battery life or might even discharge the battery depending upon the time for which the connection sustains.
