Direct Answer
A wet electric reel battery connector should be treated as a resistance and corrosion risk before the next trip. Power off the reel, separate the battery from the cable, dry the connector completely, inspect for residue, then test the reel under light load before fishing.

Symptoms
- The reel still powers on, but the connector was splashed.
- The plug feels warm under load.
- Green or white residue appears around the contact area.
Check Sequence
- Stop powering the reel.
- Disconnect the cable and battery.
- Dry the connector area completely.
- Inspect for salt residue, bent pins, heat marks, or loose seating.
- Run a short low-load test before the next trip.

Quick FAQ
Can a wet connector make a good battery look weak?
A: Yes. Moisture or salt residue can create voltage drop under load even when the battery is healthy.
Should I modify the connector if another plug almost fits?
A: No. Keep the RANON connector structure unchanged and use only a compatible cable path.
Is surface drying enough?
A: Not always. Salt residue can remain after water evaporates, so inspect and test before storage.
