You are here: Home / Blog / PEVs / How To Test A Battery's Capacity Testing a battery’s capacity is one of the best ways to determine the health of a battery cell. indicator of a battery. To test the capacity of a battery cell, you have to fully charge and fully discharge the cell while precisely measuring the energy in at least one direction.
Before conducting any tests, it’s crucial to identify signs of a potentially bad rechargeable battery. These signs include: Reduced battery life: The battery discharges quickly or struggles to hold a charge. Physical damage: The battery shows signs of swelling, leakage, or corrosion.
A discharge test determines the battery’s ability to sustain a steady output under load. Connect the battery to a discharge resistor and measure the voltage over time. A healthy battery should maintain a stable voltage throughout the test. Measuring the internal resistance provides insight into the battery’s overall health.
The good news is that you can get a 18650 or 21700 cell charger/tester that charges the cells and tests the capacity. To check the IR of an individual cell you will need a standalone 4-wire IR tester, we recommend the one below. Testing a battery’s capacity is an important part of knowing the overall health of a battery.
Connect the battery to a discharge resistor and measure the voltage over time. A healthy battery should maintain a stable voltage throughout the test. Measuring the internal resistance provides insight into the battery’s overall health. Connect the battery to a multimeter capable of measuring resistance and obtain the internal resistance reading.

Use a multimeter to judge the quality of the rechargeable battery. The following uses a lithium ion battery with a standard voltage of 4.2V as an example. If the voltage is 4.2V after full charge, it is ok. If the battery time is more than 0.7 times of the new battery, it means the battery is not bad. If the volume voltage is higher than 4.2V ...
Rechargeable AAs. Battery packs are always lower quality and/or capacity, they are not dedicated real rechargeable batteries, even the "official" ones. And yes, you will probably find people telling "they had no problem so far" because they havent compared it with actual batteries. But I have, and I can''t tell you enough, packs die faster ...
