In summary, the best solution to test a capacitor without desoldering it actually for the circuit board is either using an ESR meter or smart tweezers. Both work the same and are fine to use.
[pdf] We connect the capacitor to the LCR meter’s test fixture. We navigate through its menu to set the frequency to 120Hz, which we will use to measure Q and DF, while for ESR we will change the frequency to 1KHz. The last phase of testing is the overvoltage or torture part.

[pdf] So, can a capacitor replace a battery? Only if your application requires quick, frequent energy delivery — and not long-duration storage. Capacitors and batteries each have unique strengths — and weaknesses.
[pdf] Issue: One of the most frequent problems is when the machine doesn’t deliver enough welding power to create a strong bond between the metal pieces. Solution: To address this issue, check and, if necessary, replace the welding electrodes, and ensure the capacitor energy storage unit is fully charged.
