A 9 volt battery is used to power all sorts of electrical toys, including remote control cars, smoke alarms or digital radio scanners. For whatever reason you require a 9 volt battery, you need an good indication whether or not your current 9 volt battery is got enough power. This will then allow you to determine if you require a brand new 9 volt battery, to replace the existing battery. The most popular way of testing is to use your tongue. But if you are after accurate results from testing, using an multimeter tools would be the better option, if you have it handy.
Instructions On How To Test a 9 Volt Battery Using a Multimeter
1) Switch on your multimeter. Once its powered on, set the multimeter to read in the 'Voltage' option. This will allow it to measure the 9 volt battery specifically in volts and not in other none relevant metrics.
2) Obtain the probe wires from the multimeter. The probes look like pens, with a metal end placed on each of them. There will be two color probes, one red positive and the other black negative. Place the black metal probe onto negative terminal on the battery, also known as (-). Then place the remaining red metal probe onto the positive terminal on the battery, also known as (+).
3) Look at the reading displayed on the digital readout screen. If it shows exactly 9 volts or it is reasonably close, the battery is fully charged up and is ready to be used. If the battery voltage is below 5 volts, it is still got some remaining charge left in it and is still useable in low power devices. If it reads 0 volts, then the battery is dead and is use no longer useable in any types of electronics.
