Free QuoteThe only certain way to determine a battery capacity is to use a smart charger and/or a smart discharger (often combined into one) to profile a battery. For example, I have a 2000 mAh battery. After a few conditioning runs, either in use or on the smart dis/charger, the battery shows as having 1600 mAh capacity to 80% discharge.
Free QuoteNote that a Li-ion battery can be discharged to 3V and lower, but the battery shows 0% or ''fully discharged'' at 3.3V to ensure maximum useful capacity of the battery.

Free QuoteTest with a Different Battery: Testing your charger with a different battery helps verify whether the issue is with the charger or the original battery. If the charger successfully works with a different battery, the original battery might be defective. It is important to know the battery's specifications to ensure compatibility.
Just something you'd typically expect the battery to be able to power. If you measure the voltage while the battery is powering the load, you get a much better indication of how charged it is. I think the way a lot of commercial devices do it is with measuring the current coming out of the battery over time, known as "Coulomb Counting".
(If you have more than one mode with "V" in the name, just try all of them.) Then connect the black wire of the multimeter to the negative terminal of the battery and connect the red write of the multimeter to the positive terminal of the battery. The multimeter should tell you the voltage.
external leakage currents. First you need to check the battery. If you use it for more than 3-5 years, the battery is probably losing its ability to hold the charge. To check, disconnect battery terminals, leave it for 2-3 hours and check the voltage on contacts.
When a battery is full, the charger must stop charging. This is important for safety. The charger measures the battery's voltage and current. If the voltage is high and the current is low, the battery is full. The charger will then stop charging. There are two main ways to charge a battery. One is Constant Current (CC) charging.
Charging Rate: Check the amp rating of your charger and compare it to the battery's accepted charging rate. Using a charger with a higher amp rating than the battery can cause overheating or damage. Manufacturers usually specify the safe charging rates for each battery type.
