How to test lithium polymer battery life?

 

To test the life of a lithium polymer battery, you can perform a capacity test to determine how much of its original capacity the battery retains. Here’s a step-by-step guide on how to test a lithium polymer battery’s life:

  1. Gather the necessary equipment: You’ll need a lithium polymer battery charger with a discharge function, a multimeter, a LiPo safe bag or fireproof container, and a notepad or digital device to record the results.
  2. Fully charge the lithium polymer battery: Charge the lithium polymer battery using a balance charger to ensure that all cells are charged evenly. Ensure that you’re using the recommended charging rate for your lithium polymer battery (usually 1C).
  3. Discharge the lithium polymer battery: Using the charger’s discharge function set the discharge rate (usually around 0.5C to 1C) and the cutoff voltage (typically 3.0 volts per cell). Begin the discharge process, and the charger will discharge the lithium polymer battery down to the cutoff voltage while monitoring the discharged capacity in milliamp-hours (mAh).
  4. Record the results: Once the discharge is complete, note the discharged capacity (mAh) displayed on the charger. This value represents the current capacity of the battery.
  5. Compare the results: Compare the discharged capacity with the lithium polymer battery’s original rated capacity (found on the battery label). The lithium polymer battery life has degraded if the discharged capacity is significantly lower than the original capacity.
  6. Perform multiple tests: To obtain more accurate results, you can repeat steps 2-5 a few times and calculate the average capacity.

Keep in mind that this test only provides an estimation of the lithium polymer battery’s life based on its current capacity. Other factors, such as increased internal resistance, may impact the lithium polymer battery’s performance and lifespan.

Always follow safety precautions when handling lithium polymer batteries, including charging and discharging them in a fireproof container or safe bag and never leaving them unattended.
