What causes a car battery to self discharge?
Either there is a dead cell in the battery or something is drawing power from the battery. Even a good battery will slowly discharge over time. Normally it will take months.
What is meant by battery float charge?
The voltage required to counteract the self discharge of the battery at a certain temperature.So it is the amount of voltage given to make the battery in fully charged condition.
Why does your car battery self discharge?
Your car battery can self-discharge on the basis of chemical reaction, or due to temperature changes (when it gets colder, it has less amperage available). It can also be caused by parasitic draw due to a improper connection or a device left on. Typically if the electrical system has been evaluated and there is no parasitic power-off draw, then the battery's chemical composition may have been compromised or a cell may have been crossed. This means your battery is bad and typically needs to be replaced.
What would cause the charge light to come on followed by the gas and temp gauge to drop off on a 1987 Toyota pickup battery appearers to recover its charge after it sits for awhile?
The battery it self does not recover charge; The internal resistance of any battery will increase as it heats up - A good example is how a flash light with near-dead batterys will light the bulb for a short time, and then dim-out. If you turn it off and wait, it will repeat the process (The process of dumping available current into the lamp and then leveling-off to a zero discharge state.) The issue becomes that the potential energy (Stored in the battery) cannot overcome the resistance (of the lamp filament) - Therefore, no more current can pass through the lamp.)> With your vehicle, the same case is true - the battery, when not in use, will seek an equalibrium with it self. Once the battery cools down, the internal resistance will decrease, allowing it to apply more current to a load. Since the battery is actually below a reasonable voltage (Below 12 Volts) - there isn't much "pushing" the current that's available in the battery before it levels back to a zero discharge state. (Zero discharge state = resistance the battery needs to overcome is greater than the potential that battery has to overcome the load.) If your gas and temperature guages are electronic, and the ignition isn't on (Car not running and battery dead) - The guages will not function because they are reliant on the electronic sub-systems that provide measurements to those guages. (They are in effect "un plugged") The difference between analog and digital guages - analog guages provide proportional measurements and digital guages provide calculated measurements.
How can a person overcome self esteem?
No. But you can achieve higher self-esteem
How long does it take to carode a batterie on concrete?
Car batteries do not usually corrode just sitting on concrete unless their is a leak in the container. I do know that you shouldn't place a car battery on a concrete surface as it can cause the battery to discharge its self into the concrete and you end up with a dead battery.
What is the best discharge rate for NIMH battery?
To get the rated capacity, limit the discharge rate to 0.25C
Why does a battery discharge itself?
chemical reactions take place in battery which reduce the charge.
How long does it take a fully charged battery to completely discharge?
It depends on the type of battery, and the capacity of the battery, and the application you are using the battery for.
How do you discharge a fully charge camcorder battery?
recycle it
What is making your battery drain when the car is off?
First thing is the battery itself. It it has a dead cell it will self-discharge overnight. So have the battery tested to make sure it is good. Secondly is that there is something on pulling power from the battery. Dome, under hood, glove box, trunk, or curtorsey light. You can also have a relay that is sticking.
What happens if a car battery is not used for a long time?
If a car battery is not used for a long time, it can experience several issues due to a process called self-discharge and other factors. Here are some potential problems that may arise: Self-Discharge: All batteries, including car batteries, naturally lose their charge over time, even when not in use. This is known as self-discharge. The rate of self-discharge depends on various factors, including the battery type and temperature. If the self-discharge is significant and the car is not used for an extended period, the battery may drain completely. Sulfation: When a lead-acid battery, common in many cars, is left in a discharged state for a long time, sulfur crystals can form on the lead plates inside the battery. This process is known as sulfation, and it can reduce the battery's ability to hold a charge. In severe cases, sulfation may lead to permanent damage. Low Voltage: If the battery voltage drops too low, it can affect the performance and lifespan of the battery. Modern vehicles with advanced electronic systems may experience issues or malfunctions when the battery voltage is too low. Freezing: In cold climates, a partially discharged battery is more susceptible to freezing. When the electrolyte inside the battery freezes, it can cause internal damage and reduce the battery's effectiveness. To prevent these issues, it's advisable to take certain precautions if you know the car won't be used for an extended period: Keep it Charged: If possible, use a battery maintainer or trickle charger to keep the battery charged. These devices supply a low current to the battery, preventing self-discharge and maintaining an optimal charge level. Disconnect the Battery: If you're not using the car for an extended period, consider disconnecting the battery to prevent any slow discharge due to the vehicle's electrical systems. Store in a Controlled Environment: If feasible, store the vehicle in a cool, dry place. Extreme temperatures, whether hot or cold, can accelerate the self-discharge process. By taking these precautions, you can help ensure that your car battery remains in good condition, even if the vehicle is not used for an extended period.
