how to link 3 1.5 volt batteries to create 4.5 volts?

Answer 1

You would want to connect three 1.5 batteries in series to create 4.5 volts.
--------------------------------------------------------------------------------

Connecting in Series
When connecting your batteries in Series you are doubling the voltage while maintaining the same capacity rating (amp hours). This might be used in a scooter, Power Wheels kids vehicle, or other applications.

Just use a jumper cable between the negative of the first battery and the positive of the second battery. Run your negative wire off of open connector of the first battery and your positive off of the open connector on your second battery.

Connecting in Parallel
When connecting in Parallel you are doubling the capacity (amp hours) of the battery while maintaining the voltage of one of the individual batteries. This would be used in applications such as laptop batteries, some scooters, some ups backups, etc.

Use a jumper cable between the positives of both batteries and another jumper cable between the negatives of both batteries. Connect your positive and negative wires to the same battery to run to your application.

Answer 2

To get 4.5 volts from 3 1.5 volts batteries, they must be connected in series. You achieve this by connecting the positive terminal of one battery to the negative terminal of the other in series. You will then draw your current using the positive terminal of the first battery and the negative terminal of the third in the series. If you connect your voltmeter to these two terminals, the reading should give you 4.5 volts. But if you connect the batteries in parallel, you will only get 1.5 volts.

Answer 3

confident, I too, observed that e mail floating around. It must be a lantern battery from the present situations, reason basically this previous weekend we opened a older lantern battery, ie metallic outdoors casing and it did no longer have 32 AA batteries, it had 4 very super ie. D-cellular batteries in it. yet i'm eager to circulate purchase a plastic cased lantern battery and notice for myself! Now the place did I positioned those twine cutters and screw motive force? I purely wish the manufactures are not getting wind of this, or we are all sunk. That darn lantern battery will value $one hundred.00 money. lol

Answer 4

connect them in series.

Take one point out from the negative of one of the batteries and connect it to the positive of the other, similarly take the output from the negative of this cell and connect it to the positive of the 3rd one. Now the open positive of the first is the positive of the set and the negative of the third is the negative of the set. This will give you 4.5 V

Answer 5

You place them in series. +1.5- +1.5- +1.5- Always connect the posiive terminal to the negative terminal of the previous battery.

Answer 6

hope u want to connect three cells of 1.5 volt to make 4.5 volts
connect them in series.+ of one to the "-" of the other.
then capacity of one cell will be multiplied by total no :of cells
3*1.5=4.5volts

Answer 7

Join three of them in a line,positive terminals to negative terminals.

Answer 8

Connect the pos to neg terminals, this increases your voltage:series. If you hook them pos to pos then your voltage will stay the same but your discharge (current) will increase.

Answer 9

One + to the other - of each battery i.e. serial link
-+-+-+

Answer 10

In Series...end to end

- + - + - +
