6 FAQs about [How to detect battery pack damage]

How do you know if a battery pack is leaking?

A small scratch on a cell’s wrapping is not a major cause for concern, but if a cell is swollen, leaking, or discolored, it is discarded. If a cell has leaked, it can have a somewhat sweet smell to it. As mentioned before, lithium-ion battery packs are generally put together as a permanent, non-serviceable structure.

Can a lithium-ion battery pack go bad?

Yes. A lithium-ion battery pack that has one or more bad cells can be extremely dangerous, especially if it's put under a heavy load. Battery packs are made from many lithium-ion cells. So if one goes bad, it's more than likely going to negatively impact the surrounding cells.

Is a small dent in a battery pack a problem?

That small dent in your battery pack could be a big problem. What may seem like a superficial blemish on the outside could be a serious problem inside the cell. If a cell is dented enough (it doesn't take much) the positive and negative sides of the cell will connect. This is not always as obvious as you may think.

How do you know if a battery cell is good?

A cell with a significantly lower-than-rated capacity will no doubt have a high internal resistance. Test the resistance. Resistance is the most indicative factor of a battery cell’s SoH (State of Health). A good cell will have a relatively low resistance of about 30 to 50 mOhms.

What happens if a battery pack is over rated?

Using a battery pack above the operating temperature that it's rated for will damage the battery over time. This will result in the battery aging much faster than it otherwise would have. Time Over time, a battery is charged and discharged.

What happens if a battery fails a test?

Also, feel the battery during normal operation to make sure there are no hotspots. If the battery you are inspecting fails any of those tests, you will have to disassemble the battery down to the cell groups so that you can find out which cell group’s voltage is out of spec.
