And by the way here s how.
Car phone charger battery drain.
If charging maintaining a typical 1 5ah cell phone battery drains your 80ah service battery the float current for my cell phone charger in the car is on the order of 2ma.
Even faster if it s cold like it has been.
Avoid car battery drainage.
Leaving the charger plugged in when not charging a cell phone may also drain the battery s power but this will be a slower drain on the battery than if charging a phone.
Many of the newer car s trucks cig lighters accessory jacks now power off with the ignition switch to prevent this.
But unless you re desperate charging your iphone during your commute might be a big mistake.
When a battery gets old and you are online with the screen on the battery will slowly lose charge becaus.
It s hard to say at this moment in time as there are many reasons as to why this may be happening.
If the car is turned off just as with the lights inside the car the cell phone charger is drawing power from the car s battery.
This must be an older truck.
It s plugged into a live outlet 24 7.
In my experience this is usually the main issue.
However there are other actors that come into play like your charging port and actual device software.
So if you had a 100ah car battery and your phone s battery was 1 8ah which is equal to 1800mah a completely dead handset would pull less than 2 of the charge out of your vehicle.
So depending on phantom load of the charger it could drain the battery enough that it cannot start the car or even completely drain it.
In most cases it s usually down to the cable you are using.
The blinking stopped after i unplugged the charger.
At first it may seem harmless to plug your phone into your car s usb port.
If the car battery is old it may not be holding a full charge any more either.
A car battery holds around 800 watt hours of power.
A charger does not drain a battery any charge in a battery can be slowly lost when a charger is off and the is attached to a circuit.
