Accurate measurement requires a special battery capacity tester. If you do it as a hobbyist, you can estimate the capacity, calculate the current based on the 2 hour discharge rate, and then buy an electric oven wire to calculate the current. Likewise, by proportionally intercepting the corresponding voltage length, the discharge test can be carried out. Battery capacity can be calculated based on the product of discharge time and discharge current.
