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 are the advantages of using a low self-discharge battery compared to a regular battery?
A low self-discharge battery retains its charge longer when not in use, making it more convenient and reliable for devices that are used infrequently. This can result in longer battery life and reduced need for frequent recharging.
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.
Will an unplugged battery charger cause a battery to discharge?
No, an unplugged battery charger will not cause a battery to discharge.
During battery discharge, which species is oxidized?
During battery discharge, the species that is oxidized is the anode.
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.
How can I effectively discharge a NiMH battery using a NiMH battery discharger?
To effectively discharge a NiMH battery using a NiMH battery discharger, follow these steps: Connect the NiMH battery to the discharger according to the manufacturer's instructions. Set the discharger to the desired discharge rate, typically measured in milliamps (mA). Monitor the discharge process to ensure the battery does not overheat or over-discharge. Once the battery reaches the desired voltage or capacity level, disconnect it from the discharger. Properly dispose of the discharged battery according to local regulations.
How can I safely discharge a NiMH battery?
To safely discharge a NiMH battery, you can use a resistor or a specialized battery discharger. This will help prevent over-discharging, which can damage the battery. Make sure to follow the manufacturer's guidelines for proper discharge procedures to ensure safety and prolong the battery's lifespan.
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.
Which cell would be the most effective as a battery and why?
The lithium-ion cell would be the most effective as a battery because it has a high energy density, long lifespan, and low self-discharge rate compared to other types of cells.
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
