I have the proper tools.
Over time the joints have become intermittent.
The joints I properly crimped and soldered have never become intermittent.
I guess the molecular bond with solder is greater ; )

While many people recommend soldering crimped connectors, such as Anderson
Power Poles, it is not a very good idea. The reason(s) it is neither
required, nor desired, is partially as follows:
1. A PROPERLY crimped connection creates a molecular bond between the
conductor and the connector that is more conductive than soldering.
2. The soldering process causes corrosion because even rosin core solder
is slightly acidic.
3. The solder that flows into or onto the conductor (wire) causes it to
stiffen and increases the probability that vibration or movement will
cause the wire to break at that point.
4. The annealing of the copper wire is altered which also increases the
possibility of wire breakage due to vibration or movement.
It is absolutely necessary that the proper tool be used for the connection
being crimped. If you are going to use a crimped connection it is
imperative that you have a tool that matches the connector. If you do not
have the proper tool then DO NOT use crimped connections.
