Sure, connect anything to the battery that will use power.
No, a bad ground will not drain the battery. A dead cell in the battery will most certainly drain it. If it has a dead cell it must be replaced. Also any light that is on will drain it. Lastly a stuck relay will run it down.
Every time you run an automobile battery down, you cut the life of the battery. These batteries are not designed to be run down. They are designed to hold a charge continuously. Run the battery down three or four times and you will ruin the battery.
Something pulls battery down at night, same after new battery fitted, will be gratefull for any help. Regards. Wayne.
Cold weather can drain batteries because it slows down the chemical reactions inside the battery, making it harder for the battery to produce and store energy. This can reduce the battery's overall capacity and performance.
It can allow the drain to block easier. Take the trap off the sink drain and remove it
There's a parasitic drain somewhere.
Yes possible. If switch does not open on engine shut down battery will drain If switch does not close on start up battery will not charge
In addition to acutally driving the car, using the little features such as the lights, horn, radio, and air conditioning/heating will drain the battery of a car. Also a dead cell in the battery will cause it to run down overnight. And if something is on such as a dome light, under hood light, trunk or glove box light. A stuck relay will also run the battery down.
When the battery in your electronic device dies, you do not need to replace the entire device. Open the battery compartment and write down the number on it. The CR1632 battery is made by different manufacturers, and is widely available at electronic, department stores and online. The cost of the battery is minimal, and is far less than replacing the device itself. In a disposable world, the only thing you have to dispose of is the old battery.
A hair snare.
Yes. More so if it is connected. Most vehicles today put a parasitic draw on the battery that will drain it down over time. Parasitic draw should be under .050 mA.
No, not from something pulling power from the battery. A battery that runs down with one cable disconnected has a dead cell and must be replaced.
