DLH Heavy Duty 12 volt 18 amp onboard automatic battery charger with built in battery status indicator.
This charger is commonly used on trailers that feature an electrically powered hydraulic function.
Battery charger conveniently mounts inside trailer toolbox and the outlet housing mounts to the outside of the box.
The included mounting screws hold the lid in place on the outside, and securely mount the charger to the inside of the box.
Charger has an automatic 3-step charging process:
1. Constant-current Charge: When the battery voltage is lower than the set point it will charge the battery at its maximum current (quick charging).
2. Constant-Voltage Charge: When the battery is almost fully charged the charger will automatically limit the current.
3. Float Charge: When the battery reaches 13.5V it automatically switches to a float charging condition with a current of 0.1A–0.3A.

• (1) Battery charger unit with durable Aluminum housing
• (1) Electrical outlet cover with spring loaded lid

If the charger is beeping the battery terminals’ polarity is reversed or the battery over DC12V is connected.
To test the battery, remove AC power and press the "push" button to see the results. No lights mean the battery is dead and needs to be replaced. One light indicates poor condition, two is fair, three is good, and if your truck’s engine is running at 2,000 RPM with all four lights on, you are getting charge from the tow vehicle.
