We test on site using professional charging system diagnostic equipment. The test measures battery state of health, cold cranking amp capacity versus rated spec, alternator output, and whether the battery holds charge under load. If results confirm failure, we recommend replacement. If the battery passes, we tell you that and no replacement is needed.

Yes. On-site replacement in the ferry holding lane is the fastest and least disruptive resolution when the test confirms the battery has failed -- faster than tow extraction and the path most likely to get you on the sailing you planned. We test first and replace only when confirmed. For most common makes and models we carry the correct battery on the truck.

Yes. Mobile battery replacement comes to wherever your vehicle is -- Kingston ferry holding lane, waterfront parking, downtown Edmonds lot, or residential address anywhere in the city. We carry the correct battery for most common makes and models on the truck.

Yes. A failing alternator will drain any battery because the battery is not being recharged while the engine runs. We test alternator output on every battery call before recommending replacement. If the alternator is the issue, we tell you before replacing the battery.

For most standard vehicles the full process -- testing, confirming the diagnosis, and installing the replacement -- takes between 20 and 40 minutes at your location. In the ferry holding lane we work as efficiently as possible given the time pressure.

The Puget Sound waterfront location adds humidity and wind chill factors that accelerate battery terminal corrosion and cold-weather discharge compared to inland locations. Vehicles parked at the Edmonds waterfront -- the marina, the Underwater Park lots, and the waterfront restaurant parking -- experience more severe cold-weather battery stress than vehicles parked the same distance inland in Lynnwood or Mountlake Terrace.

We carry batteries from reputable manufacturers sized for the most common vehicle makes and models we encounter in Edmonds. Give us your vehicle year, make, and model when you call and we confirm whether we carry the correct battery before dispatch.
