DEWALT DXAEWPC4 4-Amp 12V Battery Charger/Maintainer
The DEWALT DXAEWPC4 is a fully automatic, waterproof battery charger and maintainer engineered for demanding environments. Rated IP67, it handles rain, splash, and dust, so you can use it on a boat, trailer, lawn tractor, or RV without hunting for cover. It delivers 4 amps of regulated charging to 12V AGM, GEL, and WET batteries, and automatically switches to maintenance mode once full.
Waterproof Construction and Connections
Sealed housing and waterproof connectors make this charger ideal for seasonal vehicles and marine use. Two connection options—powder-coated battery clamps or terminal rings—let you choose the fastest, most secure hookup for your battery.
Indicator Light Meanings and Error Codes
The DXAEWPC4 uses a three-color LED display to keep you informed. When connected to power, a green light indicates the unit is ready. A solid yellow or flashing amber means the battery is charging. Once the battery reaches full charge, the green light stays lit in maintenance mode. If you see a blinking red light, the charger is signaling a fault—usually reverse polarity, a short circuit, or a battery that won’t accept a charge. Check your clamp connections and confirm the battery is not defective before resuming.
Protection and Safety
Built-in circuit protection guards against overcharging, reverse polarity, and short circuits. The charger is also ETL certified for performance and safety, and includes mounting holes plus a detachable 360-degree rotating hook for convenient installation near your battery.
