Car Battery Flat After 2 Days
Car Battery Flat After 2 Days. That, or the battery is spontaneously losing charge. When i pull the dc cut fuse the current drops to ~100ma.
The battery drains flat after two days of sitting. You may have excess current being drawn somewhere in a circuit while the car is not running. If the weather gets too high (above 100 degrees) or drops too low (below 10 degrees fahrenheit), this will result in a bad impact on your car battery.
Has New Battery, Starter, And Alternator.
The dealer told me that they have had a number of reports of the same thing and the new cars in their lot they regularly have to take a booster battery to start them. Today i've checked the battery drain using a multimeter with everything off and the car locked. When your car is running the cars alternator is charging the battery, this is why you should see a higher voltage.
Make Sure All Doors Are Closed And Car Is As Quiescent (Nothing Running, Everything Closed) As Possible.
30 mins is definitely not long enough to charge a flat battery though, an hour minimum, preferably two! At these rates my battery would probably be flat in 7 days and a little more that 2 days, respectively. Does the battery have an insulating blanket.
300 Milliamps Does Not Sound Like Much, But It Is.
If i drive the car daily, the battery has enough juice to start the car. Few days ago the battery in my car was completely flat after only 2 days of not using the car. Its also to do with amps.
I Mean Totally Dead, Not Just Weak.
It drops about 25 ma. Is the car only driven every 3 or 4 days or does it start for the first couple of days, then fail on the 3rd or 4th day of use? If the weather gets too high (above 100 degrees) or drops too low (below 10 degrees fahrenheit), this will result in a bad impact on your car battery.
Opening The Memory Fuse Thus Results In A Reduction Of About 16Ma (75%) In Only The Base Current Drain.
The battery is not being recharged while the vehicle is being driven (you have a charging problem) How fast your car battery will drain and why (charts) That, or the battery is spontaneously losing charge.
