There is also a knob in the center which you’ll have to adjust in order to select the right function and appropriate range. Whether you are using one type or the other, both multimeters have two leads (red and black) and three different ports. For basic users the benefit will come as the digital multimeters are easier to read and to carry. The cost range will change considerable from basic versions to advanced versions. However they are not as accurate as digital ones.ĭigital multimeters are more expensive and they show the results on an LCD screen. The multimeter has a needle that will move over a graduated scale which is great for detecting slow voltage changes as the needle will be seen moving over the scale. There are analog and digital versions that work as useful tools for simple and complex test from battery voltage to complex diagnostics.Īnalog multimeters are sensible, complex tools and must be handled carefully. Multimeters are instruments used to measure and test electrical voltage, amperage or resistance. Make sure the voltage or current doesn’t exceed the max rating of the tester and never let the bare metal ends touch during and energized test. Always refer to the user’s manual to avoid risky procedures, understand safety precautions and limits. Also, several batteries must be discharged before testing to avoid any type of reactions such as fires (as it happened to Samsung a couple of years ago).Īs mentioned above, the application of a tester represents safety hazards that must be considered. Opening any object without reading the manual may result in considerable damage to the battery or the object itself. However, before opening any device or removing the battery you must consult the owner’s manual of the device. In most of the cases the battery is attached and it will need some extra work to take if off. Therefore, how do you test a lithium ion battery to make sure it has the right capacity? First of all you must remove the battery from the device. On the other hand some of the external factors that may affect the life expectancy are the temperature, overcharging and/or using the wrong charger. On one hand the average life expectancy for this batteries is of about two to three years, but there are some that can be measured by the total amount of full charges that it can handle before noticing a decrease in the charging capacity. This kind of loss in capacity happens due to the life expectancy of the battery. Whether you are a lithium battery expert or not, everybody has experienced over time the loss of charging capacity of their electronic devices. The separator: As the name expresses it is the barrier that will maintain the cathode and anode apart.It enables the conduit of lithium ions from the cathode to the anode. The electrolyte: Is the connection between the cathode and anode.The anode: It has two functions as it is used to store the lithium ions when the battery is charged and it facilitates the electric current flow through an external circuit.The cathode: Is where the lithium ions come from and it’s the part that determines the voltage and capacity.The lithium-ion batteries are formed by four components: cathode, anode, electrolyte and a separator. These batteries also have a high energy density and low self-discharge. Previously used only in personal devices, they are now being used for military or evenspecial purposes. The lithium-ion batteries are growing in popularity as they are commonly used in modern portable electronics and have different applications. Their usage varies from a wide range of daily products as they can power devices such as cameras, calculators, remote controls, among others. These type of batteries are also known as disposable batteries as the lithium-ion (Also known as li-ion batteries) are rechargeable. They usually have a range of voltages between 1.5V and 3.7V. The former battery has a metallic lithium as anode and they are well known for their charge density, which equals a long life and high cost per unit. One of them are the lithium-metal batteries and the other ones are the lithium-ion batteries. There are two main different types of lithium batteries. If you want to find out how to test lithium batteries using a multimeter and whether it’s the safest choice, keep reading. Lithium batteries are well introduced into modern devices by now, and it’s only normal for you as a user to find out if they’re working correctly and delivering the appropriate voltage. As for capacity analysis, you can also check: How to Test Lithium Ion Battery Capacity-Testing and Care.
