When to Use the 25ft Extension
The 25ft extension covers marina and dock storage where the outlet is at the dock structure and the battery is aboard a boat in the slip, large workshops and storage facilities where a single wall outlet serves multiple vehicles spread across the space, detached outbuildings where the outlet is near the entrance and vehicles are stored at the back, WaveCharge multi-bank installations where one or more banks require maximum cable reach, and any seasonal storage setup where the outlet location and the battery location are far apart.
Maximum Extension Length
The maximum recommended total cable length when daisy-chaining Battery Tender® SAE quick disconnect extension cables is 33 feet. Do not exceed this limit as excessive cable length can cause voltage drop that affects charging performance.
