Causes of Bad Battery Cell Failure

Overcharge and Discharge

Charging a battery too long can hurt its inside parts. If you leave it plugged in after it is full, it gets hot. This heat puts stress on the cells. Letting the battery run out all the way is also bad. Both overcharging and deep discharge make the battery not last as long. Always use a charger that fits your battery’s needs. This helps stop these problems from happening.

Tip: Take your device off the charger when it is full. Doing this keeps your battery from getting stressed.

Physical Damage

Physical damage is one big reason battery cells fail. Dropping your device or hitting it can break the battery case. Cracks or dents let air and water get inside. This can cause bad reactions. Even small drops can hurt the battery inside. If you see damage, stop using the battery right away.

Aging and Defects

Batteries get old as time goes by. When a battery gets older, it cannot hold as much charge. You might need to charge your device more often. Sometimes, batteries stop working early because of factory mistakes. Problems in how the battery is made can cause it to fail soon. Research in the Journal of Power Sources says low-quality batteries with these problems can get too hot or stop working fast. Always pick batteries from brands you trust to lower the chance of early failure.

Internal Shorts

Internal shorts happen when parts inside the battery touch each other. This can be from damage, mistakes, or even dust inside. An internal short can make the battery hot very fast or even start a fire. If your battery gets hot for no reason, stop using it and get help from an expert.

Note: Never try to open a battery by yourself. Internal shorts are risky and need a professional to fix.

Testing for Bad Battery Cell Safety

When you want to test dead battery cells, you must always put safety first. Lithium-ion batteries can be dangerous if you do not handle them with care. You need to follow safety precautions before, during, and after testing. This section will guide you through the main ways to test your battery and help you decide when to get professional help.

Visual Checks

Start with a visual inspection. This is the safest way to spot problems before you use any tools. Look for signs that show the battery is not safe to use.

Steps for Visual Checks:

2. Place the red probe on the positive terminal and the black probe on the negative terminal.
3. Read the voltage on the display.
4. Compare the reading to the battery’s rated voltage (usually printed on the label).

If the voltage is much lower than the rated value, the battery may be dead or unsafe to use. For most lithium-ion cells, a voltage below 2.5V means the cell is likely damaged.

Safety Alert: Never try to charge a battery with very low voltage. Charging a deeply discharged cell can cause overheating or fire.

Always use the charger recommended by the manufacturer. Do not leave batteries charging overnight. Monitor the battery during charging and stop if you notice any heat or swelling.

Load Testing

Load testing checks how the battery performs under normal use. This test helps you see if the battery can deliver power safely.

Steps for Load Testing:

1. Connect the battery to a device or a battery tester that draws a safe, steady current.
2. Watch the voltage as the battery powers the device.
3. If the voltage drops quickly or the battery gets hot, stop the test.
4. Note how long the battery lasts under load.

A healthy battery should keep a steady voltage and not overheat. If the battery fails this test, it is not safe to use.

Note: Only perform load testing if the battery passed the visual and voltage checks. Never test dead battery cells that show signs of damage.

Keep batteries in a cool, dry place during testing. Store them in a fireproof box when not in use. Avoid testing near flammable materials.
