There are two measures, cell voltage and specific gravity of the electrolyte. Cell voltage is the simplest to measure. For most automotive, flooded cell (having liquid electrolyte) batteries, 12.6 volts is considered full charge, although it is typical to have 13 volts or a bit over.
The specific gravity of a fully charged battery, measured with a hydrometer, is 1.265.
This depends on the actual battery and what it is made of. A 1.2 volt rechargable NiMh battery typically gives off a voltage of 1.3 to start with, then it rapidly goes down to 1.2 volt where it stays stable until almost empty, then it quickly drops below and down to .5 volt or even further down.. The same applies to Lead Acid or NickelCadmium batteries. Different types of batteries have different properties. NickelCadmium normally are able to give a lot of current until empty. where as the current you get from a NiMh battery is rather limited. Lead Acid are capable of a very high current but still dependant on the internal design of the battery. Unfortunately one can not give a correct (for all) answer to a general question. Regards.
Well, tubular tells you that it's tube shaped, like a section of pipe. Batterytells you that it has more than one cell.Lead acid tells you that what chemistry it is - lead-acid - and cell tells you that there's only one section to it. Knowing the number of celss and the chemistry means that you can figure out which voltage it should have when fully charged etc.Now, to make things maybe a bit more complicated, you could use lead-acid cells to build a tubular battery.
Alkaline batteries are named for their highly alkaline electrolyte solution which is potassium hydroxide (aka caustic potash, aka "traditional" lye) mixed with water. Lead-Acid batteries are similarly named in-part after their highly acidic electrolyte solution consisting of 35% sulfuric acid and 65% water.
I think you mean 35Ah (Ampere-hours) This depends on the amount of energy that can be stored. The amount of energy in car batteries is usually expressed in Ah, and depends on the voltage of the battery. In Europe, mostly 12V, 40Ah to 70Ah. Let's say a battery of 35Ah 12V (in reality, a fully charged lead-acid battery will have 12,65V over its open poles) needs to be fully charged. 35Ah means tha it can, theoretically, deliver 35A at 12V during 1 hour. That's is a total power storage of 12x35 = 420Wh = 1512kJ (kiloJoules) The amount of current flowing into the battery will charge (by an electrochemical process) the battery. So it's not really the voltage of the battery, but the current that's important. Unless you know the internal resistance of the battery, You can not really calculate this. But now practical. You can charge a car battery at a pretty high current, although quality deteriorates with higher currents (that's why professional chargers will use a pulse charger) , so your 13,5V will not be too high. Car generators can deliver up to 16Volts to a battery. What I suggest is this: measure the battery voltage, load the battery with the 13,5V, and measure again after 10 minutes. Check the voltage of the battery, and do not exceed 12,5V. Even better: Load the battery, and meanwhile measure the current and voltage. Now you can calculate the internal resistance of the battery. A word of caution. Car batteries contain a highly poisonous fluid, a mix of water an sulfuric acid. Don't play around with it, DON'T SHORT IT, don't reverse polarisation, This fluid causes severe burns. Be careful.
No, Terminal voltage of a battery can't be zero. For example, if my mobile's battery is at low charge. It is showing only one point of charge on screen, but there will be no fluctuation on its screen, all the other features like audio, video, display will remain same unless it will become fully out of charge. Charge could be zero but the voltage can't be zero. Well, actually the terminal voltage of a battery can be zero, but only when the battery is totally dead and unable to take a charge (if it was a rechargeable type battery). At this point it must be disposed of. One exception is wet cell batteries (like lead acid), if the liquid electrolyte is removed the terminal voltage goes to zero but the battery is still good and can be restored to normal operation by refilling it with electrolyte. In fact wet cell batteries are often sold fully charged but with no electrolyte and their terminal voltage is thus zero on the store shelf until the salesman fills them with electrolyte.
The answer is C 1.3.
About 1.265 (taken from Wikipedia)
The relative density of a fully charged battery is typically around 1.28 to 1.3 for lead-acid batteries. This measurement can vary based on the type of battery and its specific composition.
When a battery is fully charged, the amount of sulfuric acid mixed with the water is sufficient to give a specific gravity of about 1.3. The answer is C. I found this on Page 78 of the Mechanics Study Unit of Physical Science (Penn Foster). One of the uses of a hydrometer is to measure the condition of electrolyte solution in a storage battery of the type used in a car. When a battery is fully charged, the amount of sulfuric gravity of about 1.3.
when a battery is fully charged , the amount of sulfuric acid mixed with the water is sufficient to give a specific gravity of about 1.3 when battery is discharged to 50 percent, the specific gravity reading should be 1.2 any specific gravity reading that's less than 1.1 usually indicates a dead batteryThe answer isC. 1.3.
The relative density of the electrolyte in a fully charged state for lead-acid batteries is typically around 1.280 to 1.300. This measurement indicates the concentration of sulfuric acid in the electrolyte, which is important for maintaining the battery's performance.
The negative electrode supplies electrons to the external circuit (or load) during discharge. In a fully charged lead-acid storage battery the negative electrode is composed of sponge lead (Pb). The positive electrode accepts electrons from the load during discharge. In a fully charged lead-acid battery the positive electrode is composed of lead dioxide (PbO2 ). It should be noted that the electrodes in a battery must be of dissimilar materials or the cell will not be able to develop an electrical potential and thus conduct electrical current. The electrolyte completes the internal circuit in the battery by supplying ions to the positive and negative electrodes. Dilute sulfuric acid (H2 SO4 ) is the electrolyte in lead-acid batteries. In a fully charged lead-acid battery, the electrolyte is approximately 25% sulfuric acid and 75% water.
It depends on the state of charge. A fully charged lead-acid 12V battery will measure around 13.6V, the same battery at the end of useful charge will be approximately 10.5V
the more the battery is charged, the less water. dead battery is close to 100% water. charged battery is close to 90 - 100% sufuric acid
An 8-volt battery, commonly found in certain types of rechargeable batteries, typically contains a lead-acid electrolyte solution. The amount of acid in such a battery varies depending on its size and design, but it generally contains a mixture of sulfuric acid and water. The concentration of sulfuric acid is usually around 30-40% by weight in a fully charged lead-acid battery. The specific volume of acid can vary widely based on the battery's capacity and configuration.
First it would depend upon the type and voltage rating of the battery. If it is a lead acid battery, I would recommend charging it to its recommended voltage and load testing it. A fully charged 12 volt automobile battery should read 12.6 volts. A battery that reads 10.5 volts is completely drained. If the battery is fully charged and only read 10.5 volts it needs to be replaced.
To check the specific gravity of acid in a car battery, you'll need a hydrometer. First, ensure the battery is fully charged and then carefully remove the vent caps. Insert the hydrometer into the electrolyte solution, squeezing the bulb to draw in the liquid, and then release it to allow the float to settle. Read the specific gravity measurement on the scale; a higher value typically indicates a fully charged battery, while a lower value suggests it's discharged.
