Normally two. A positive and a negative.
On specialist battery packs (like for a laptop or phone) you may find more terminals. These are used for temperature and current monitoring, for charging purposes.

Are lithium batteries and normal pencil batteries are same?
Lithium batteries are button type.
What branch of science is batteries in?
Batteries come under Chemistry, which is a subset of Physics.
Are double A batteries rechargeable?
Only batteries that are marked "Rechargeable" are rechargeable. Are others are single use.
What is the proper way to dispose of used batteries?
To get rid of used batteries contact your waste management company. They'll send over a special collection crew to dispose of batteries.
Why are 9-volt batteries rectangular but AA batteries are circular?
Button batteries, AA, AAA, D and C batteries are a single cell. 9-volt batteries contain multiple cells to get a higher voltage and therefore are the shape they are. Open a 9-volt battery and you will see the cells inside - make sure you wash your hands afterwards though!
What kinds of terminals do batteries have?
Positive & Negitive
How do you shorten batteries?
connect its two terminals with a wire.
What kind of terminals do batteries typically have?
Positive & Negitive
What function is performed by battery terminals?
The function of battery terminals is to connect a load or charger to a cell battery. Battery terminals are necessary and common in a lot of batteries.
How much terminals do batteries have?
Normally only two, a positive and a negative terminal.
Do alkaline batteries have to be taped for shipment?
Yes, it's not because of the material inside the battery, but to prevent the terminals from touching other batteries. If battery terminals touch they can create heat which, in turn, can cause a fire. So to prevent a fire, you should tape all battery terminals when shipping for recycling.
Is electric shock from batteries possible?
With enough batteries to get sufficient voltage - sure. Put your tounge to the terminals of a 9 V battery and you'll see.
How do you place charging leads to two 6 volt deep cycle batteries that are in series?
If the charger is a 12 volt DC machine, connect the leads to the two battery terminals that the load is taken from. Take care to note the polarity of the leads to the polarity of the battery terminals. There will be a short jumper cable between the two six volt batteries. The charger leads go on the opposite terminals of the two batteries that the jumper is connected to.
What is the difference between U1R-7 and U1P-7 batteries?
Negative and positive terminals are reversed.
What happens if two lots of 12dc volts are applied?
It depends how they are connected. If the terminals of two 12 volt batteries batteries are connected to the same circuit (in parallel) then there is no change in the flow of current- it will just last for twice as long a time. But if two opposing terminals of the batteries are connected to each other first and the free terminals then connected to the circuit (in series) then there would be a total voltage of 24 volts and twice as much current would flow. The two batteries would last for the same length of time as one battery on its own.
How do you connect 2 12v batteries to get 24v?
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.
What to use to clean rechargeable battery terminals?
For the power to flow from your batteries to the device they are supposed to power there needs to be good connections at the battery terminals. With disposable batteries you were guaranteed new terminals each and every time you changed batteries so there was little need to clean the terminals, but with more and more people nowadays powering their GPS receivers and other devices with re-chargeable batteries it's becoming more important to clean the terminals on the batteries regularly. There are a number of ways you can do this. You can use one of the myriad terminal cleaners that you can find in camera or electrical shops. The gadget to look for is the one that looks like a pen but actually has a fiberglass tip, this I find is the best battery cleaner around. Failing that, you can take some fine sandpaper to the terminals - it works just as well (if not a bit too well - don't go overboard on cleaning!). As a rule I give the terminals a clean before re-charging the battery - this way the battery gets a good charge (muck on the terminals affects charging too) and they are then ready for immediate use.
