Testing a lithium-ion battery is a sure way to tell if it’s bad. You can test these metrics if you don’t notice any visible signs but suspect the lithium-ion battery has reduced capacity, a high self-discharge rate, or constantly low voltage. It involves measuring the battery’s performance and comparing it with the manufacturer’s specifications.
It’s not just about ensuring your device stays powered on, it’s also a matter of safety. Lithium-ion batteries can be volatile if they’re not properly maintained and monitored. The importance of testing lithium-ion battery health can’t be overstated. When we neglect this, we risk unexpected shutdowns or, worse, battery failure.
A healthy lithium-ion battery should read within the expected voltage range. If the voltage reading is lower than expected, it may say a failing battery that requires attention. Understanding the expected voltage range for your specific battery is vital for interpreting the results.
A lithium-ion battery, or any other battery for that matter, may be bad if you notice any one or more of the following signs and symptoms: Overheating and swelling are visible or obvious signs, whereas the others are intrinsic symptoms. Visible signs are high-level warning signs that should not be ignored. Doing so could pose a threat.
The normal self-discharge rate of a lithium-ion battery is normally 2-3% monthly, which is low. Set the multimeter to measure DC volts. Connect the multimeter’s red probe to the battery’s positive terminal and its black probe to its negative terminal. The picture below shows this test performed on a lithium battery (18-20V) power tool.
Do not attempt to charge or use a damaged battery as it can be dangerous. If your battery is not holding a charge for as long as it used to, it could be a sign of a bad lithium-ion battery. Over time, lithium-ion batteries lose their capacity to hold a charge.
