9 Volt Battery- What You Need to Know


A 9 volt battery is the most commonly used device. It is produced as a rectangular prism. The 9 volt battery is generally used in pocket transistor radios, fire detectors, carbon monoxide alarms, guitar effect units and vehicles used as means of communication. It is also used as supporting power in digital wall clocks and alarm clocks. The 9 volt battery is made of alkaline material and is assembled with six individual 1.5V LR61 cells enclosed in a wrapping. 9 volt battery cells are to some extent smaller than the regular LR8D425 AAAA cells and can be used in their place in some equipment even though they are shorter by 3.5 mm.

How can a 9 volt battery be checked?

A typical 9 volt battery also technically known as a PP3 is rectangular in shape and has both the positive and negative terminals on the crown. In general, a 9 volt battery is made of six 1.5-volt batteries that are wired in a sequence. Such a battery is made of carbon zinc and zinc chloride or any alkaline chloride and is used in equipment and gadgets like radio-controlled devices and hand-held video games that need more electrical energy but require small amount of current to activate. The power status of a 9-volt battery can be checked with a low current voltmeter.

In order to check a 9 volt battery, place the battery on a smooth surface so that you can have a clear view of both the positive and negative terminals as they are positioned side by side. Choose the accurate voltage on your voltmeter and set it in the series of 5 to 10 volts so that you get accurate voltage reading. Then you have to connect the black negative wire attached to your voltmeter to the negative terminal of the 9 volt battery. The wire coming from the voltmeter has a tiny spring clip at the end which makes it simple to hook up to the battery terminal. Then join the red positive wire to the positive terminal of the 9 volt battery and ensure that both the clips are attached to the terminals. Finally, you can look at the display on your voltmeter to find out the accurate voltage of your battery in order to tell how much power it has.

How to connect two 9 Volt batteries in sequence?

Knowing the process of how to connect volt batteries in series can be very advantageous and useful. This connection helps in making use of mutual voltages of the batteries. In case you have a gadget that requires an 18-volt power source but have two 9-volt batteries, you can connect both of them in sequence to attain the 18-volt power source you need. In order to do this, you have to hook up one end of a jumper wire to the positive terminal of the 9 volt battery. Then you have to connect the other end of the jumper wire to the negative terminal of the second 9 volt battery. Adjoin the positive terminal from the mechanism you are sending power to the negative terminal of the first battery and finally you have to join the negative lead from the gadget you are sending power to the positive terminal of the second battery to complete the job of connecting two 9 volt batteries in sequence.
