Here are some relevant factors about titanium deck plates:

Users with titanium deck plates won’t experience any corrosion on the receptacles, but banana plugs will likely corrode faster because titanium is more dissimilar from copper (when compared to legacy deck plates and all cable harnesses).
Gen7 Serial Timers use 4.0V and Legacy uses 3.6V. These lower voltages will reduce the rate of galvanic corrosion.
Some galvanic corrosion will still occur even when no voltage is present.
