How do I keep my light bar from draining my battery?

Follow these 8 tips on how to keep a light bar from draining your battery:

1. Connect your light bar directly to the vehicle battery or another DC voltage source.
2. Use a wire gauge that matches or exceeds the maximum current of your LED light bar.
3. Fuse power wires to the expected current draw, not the wire size.

With this power draw, even IF you leave your LED headlights on the whole night, they will not drain your battery as halogen headlights would have. Just like stock LED lights don’t drain your car battery, neither do aftermarket LEDs for projector headlights.

How long will a light bar run on a battery?

I found out that battery’s have use 100-200W per hour, most battery’s are 1000W so if what the guy who said this is correct the light should last about 5 hours, But also depending on the life of the battery, if its full and weather. They could all change how the battery lasts so id say atleast 3 hours.

How long does a car battery last if interior lights are left on?

A car with the interior lights left on could likely survive six to eight hours, as long as the battery were fully charged and in good condition, in warm weather.

Can you run LED lights from a 12V battery?

Most LED lights are arranged so that they can run off of a 12v battery—in fact, 12v lights can cause a short when plugged directly into a socket, which usually have 110v current. This can be very dangerous, and so the best solution is to run these lights through a relay instead. Check out some battery-powered LEDs intended for use in a car.

How does a battery drain while plugged in?

I also let the battery drain from 96% to 40% or 60% while working and then plugged it in, the battery starts to charge and reaches +10% or maybe +15% and then stop charging and starts draining out again. In all the above scenarios the draining of the battery is at regular pace, I.e. no fast draining nor sudden sgutdowns…

Is it possible to charge a battery while plugged in?

I already ran battery test severl times and the results are always ‘Passed’ (when charged at 5%, 20%, 76% or 95% , plugged in or not makes no difference), after positive test result you can never reach the stage/option of calibrarion…

Why do my house batteries not charge when I run the engine?

They will read very low if no charging voltage is present. The house batteries (as well as chassis batteries) should charge when the engine is running, if not then you should find a fuse in a positive 12 volt feed between them and the alternator.

What happens to batteries when plugged in to shore power?

When plugged into shore power at the campground, presumably the AC to DC converter will charge the auxiliary battery bank. All the lamps, fans, water pump, etc., still operate on 12-volts DC, just that the DC electricity is provided by the converter instead of the batteries while plugged in.

Why do my lights not come on when not connected to shore power?

With 12 volts present when the charger is running when on shore power, one would suspect there is a wire routing issue, as you should get 12 volts from both the charger and or the batteries if things are connected properly. I have a feeling that you do not have 110 volts from the inverter output when you are not connected to shore power.
