many car owners probably had to deal with the problem of incorrect battery.It so happens that the car stood all day and start it then becomes impossible.However, even a long battery charging does not help.These symptoms show a decrease in the density of the electrolyte.On what should be the density of the battery, why it falls and how to raise it to the correct level, and we will discuss in this article.
electrolyte and electrolyte density
- a solution composed of sulfuric acid and distilled water.These components are contained in approximately equal parts water - 1 part sulfuric acid - 1.25 parts.Indicator 1.25 - this is the density of the vehicle's battery.The performance properties of the battery are directly dependent on this index - the higher it is,
the lower the freezing temperature of her, and she is in good working condition.Knowing what should be the density of the battery, it is possible to judge about the real state of your device.
Metering density battery
Before you check the density of the battery, you should get a special instrument called a hydrometer.It is a device consisting of several rubber and glass elements.Since
the electrolyte is a dangerous chemical compound, before measuring its density is necessary to take care of the precautions, namely to carry out the work in rubber gloves to avoid contact with liquid on the skin and clothing.It is strictly forbidden to smoke!
Open the mouth of the can, insert the tip of the device and with the help of a little pear type electrolyte so that float hydrometer floats freely in the body, without touching the bottom, sides and top.Wait until the liquid in the device settle down, and holding it at eye level, visually count readings.Perform this procedure with all banks.If the difference is greater than the density of 0.01 grams per cubic meters.see, be sure to add the distilled water or put the battery on charge leveling.By reducing the density to a value of 1.24 grams per cc.cm or below the battery should be recharged.
Additional recommendations
is important to know not only how to check the density of the battery using a hydrometer,
but also the rules for amending the indication of the instrument in specific temperature conditions.The optimum temperature of the electrolyte to measure its density is 15 - * 25 ° C, but if you have to carry out this procedure at a higher or lower temperature, the reading must be corrected.
| electrolyte temperature (? C) | Amendment to the hydrometer readings |
| - 45 | - 0,04 |
| - 30 | - 0,03 |
| - 15 | - 0,02 |
| 0 | 0 |
| + 15 | 0 |
|
+ 30 | + 0,01 |
| + 45 | + 0,02 |
| + 60 | + 0,03 |
notWe should find out what the density of the battery, after there has recently been topped up
water, or after repeated attempts to run the starter.After completing all procedures thoroughly rinse the hydrometer with water.
How to increase the density of the battery?
The easiest way to maintain the required level of electrolyte in the battery is topped up with distilled water.However, the majority of car owners forget or do not know that you need to periodically measure the density of the battery, asWater boils over time, and with it, and an electrolyte, which causes reduction in the density, sometimes up to a critical point.When the battery is completely
refuses to work, then there arises the burning question: "How to increase the density of the battery?"
using the instructions below, you will be able to extend the life of the battery.However, remember that this procedure requires special attention and care.
Precautions
• Observe the maximum caution when working with electrolyte: All actions are performed in protective glasses and rubber gloves.
• With self-dilution of the electrolyte must be sure to add the acid to the water, but not vice versa!These fluids have different densities, and the result of an error could be serious burns.
• It is forbidden to turn the battery upside down, becausetherefore an active surface of the plates may peel and cause a short circuit.
• Be prepared to provide the capacity to drain the old electrolyte and prepare a new mixture.
• Please check for plastic, to be used for sealing holes for resistance to the electrolyte.
• Remember that a charged battery will have a higher density.
preparatory stage
In order to raise the density of battery electrolyte require:
• hydrometer;
• measuring capacity;
• Enema-pear;
• soldering;
• Drill;
• electrolyte;
• battery acid;
• distilled water.
How to increase the density of the electrolyte in the battery: detailed instructions
produce measurements of density of the electrolyte in each bank.With that in mind, what should be
density of the battery, compare their actual performance.So, if the density is 1.25-1.28, and the spread of values in each bank is not more than 0.01, the battery works well, and any procedures it is not required.If the rate varies on the level of 1,18-1,20, the only option is to top up the electrolyte with a density of 1.27.
• From one bank evacuate via enema pear-old maximum amount of electrolyte and measured its volume.
• Fill with fresh solution in an amount of half of the evacuated.
• Actively but gently shake the battery to mix the liquid.
• measured density.If not so, what should be the density in the accumulator, add another ½ of the remaining amount of electrolyte.The operation should be repeated until you get the desired performance.
• Balance top up with distilled water.
What to do with the critical density level
If a density below 1.18, then to solve the problem of electrolyte topping fail.In this case, it requires battery acid, which has a substantially greater density.This process is carried out similar to the scheme of adding electrolyte.If at one time did not achieve the desired results, repeat the procedure a number of times.If the battery
density even below 1.18, it is necessary to resort to the procedure of complete replacement of the electrolyte.To do this, just need to pump out with a blower maximum amount of the solution.Then, battery banks are hermetically close the vents plugs.Put to one side and turn the battery drill 3-3.5 mm hole in the bottom of each of the cans.Before prodelyvat next hole, drain the remnants of the previous electrolyte.
Next, thoroughly rinse the battery with distilled water.Then solder bores acid plastic (for example, for this you can use plugs with unnecessary battery).
done all the preparation procedures, you can start pouring fresh electrolyte.In this case, use a solution prepared independently, the density of which is slightly higher than that provided for your climate zone.At the same time it should be noted that even a complete replacement of the electrolyte in the battery is old he will not be able to provide the same service life as in a new battery.
Tip: if you want your battery served as long as possible, do not forget to charge it in time, and periodically check the density.
