Sometimes access to the electrolyte is required for battery maintenance or diagnostics, but in the absence of access, many motorists want to remove the battery cover.
Batteries are divided into batteries with access to electrolyte and without access to electrolyte. In order to unscrew the battery plugs with access to the electrolyte, you will need a ruble coin or a wide screwdriver. If the battery has a single bar-shaped cover, you will need a screwdriver (panel-cover, remove with a screwdriver). But there are batteries that do not have access to electrolyte, so motorists often turn to specialists with advice to help remove the cover from the Wart or Bosch battery.
How to remove the battery cover Varta, Bosch, Atlas, Delkor, Bost, Banner
If you need to remove the cover from these batteries, then after removing the cover, the battery can be thrown away. Those. Batteries Varta, Bosch, Atlas, Delkor, Bost, Banner will not work because the cover is non-removable. Technologically, the pad is soldered at the factory and does not imply dismantling from the battery.
If you want to remove the panel from the cover, then you need to know that there is no access to the electrolyte - this is a labyrinth system for vapor condensation. But there is one exception here - if you find that the electrolyte level is lower than necessary (for example, determined by weighing,) then a medical syringe and an awl will help you. It is necessary to carefully make a hole, trying not to damage the labyrinth system, add electrolyte with a syringe, and then solder the hole.

CENTRA FUTURABatteries have many advantages such as:
- the best starting parameters;
- additional power and extended service life;- a reserve of greater capacity - in connection with the use of thicker plates;
- the ability to work effectively in conditions of a sharp increase in ambient temperature (unlike standard batteries).- the reliable double tight cover having the patented system of labyrinths;
- indicator Magic Eye, the so-called "magic eye"; thanks to it, you can control the level of battery charge;
- the use of envelope separators made of porous polyethylene produced by Daramic prevents short circuits

TEST RESULT
Declared battery current 600 A. Capacity 60 Ah.
Reserve tank CENTRA FUTURA turned out to be one of the lowest among the tested batteries, it withstood a load of 25 A for 97 minutes. The battery start energy with the declared current was a good 22.93 kJ, the start energy indicator at -18 degrees turned out to be an average of 19.96 kJ. Lowering the temperature to -30 batteryCENTRA FUTURA could not stand it and could not work for 30 seconds under load necessary for launch energy determination, holding out for only 24 seconds.
SUMMARY
CENTRA FUTURA battery with very average performance.
Modern power sources for cars require less and less human participation in the operation process. Batteries of a maintenance-free type do not need topping up with water or electrolyte for the entire period of operation. If the owner likes the battery, but the indicator says that the resource has been exhausted, is it possible to restore the battery? How to open the battery and get lead plates for fishing?
Unmaintainable power supply is attractive to those who do not want to worry about the condition of the power supply. However, many are accustomed to control all elements of the automotive system. Traditionally, it is believed that a sealed battery cannot be opened. Indeed, there are no technical holes on the case of such batteries. However, if you want to make a car battery serviceable or get lead out of it, then you can disassemble a maintenance-free power supply. This will require some tools and knowledge of safety rules.
What types of lids are available
The contents of any car battery is enclosed in a case. Serviced batteries are distinguished by the ability to access the banks and, if necessary, add electrolyte or distilled water. The maintenance-free sealed type battery is characterized by a smooth housing surface. To avoid any contamination, the top of the battery is tucked under the cover. It can be removable - on latches or monolithic - heat-welded to the body. Most often, a closed-type battery has a monocap.
What tools are needed to open
To gain access to the fill holes, even if they are filled at the factory to the level of the surface of the case, it is necessary to remove the cover from the battery. How to open the battery cover? If it is in the grooves, then carefully snap the fasteners and remove the element. You may need a flathead screwdriver.
A hot pressed part will not come off easily. During its dismantling, the probability of breakage of the part is high. Therefore, we do not recommend removing this type of element. However, if you wish, you can try to break the integrity of the part with an awl, screwdriver or drill. You will not remove the cover completely, but you can make holes for further operations.
How to open a maintenance-free battery
There are not so many ways to open a closed-type power supply, and they depend on the goal. If lead is needed (for hunting or fishing), then you don’t have to worry about how to open the battery and just break its case.
Attention! Drain the acid solution first!
In order to extend the life of the battery, it is necessary to make holes that will give access to the banks.
- Remove the stickers from the surface of the battery.
- Examine the body carefully. Since the sealed lead-acid battery was filled in at the factory, the stamping of plugs remained.
- Take an awl, screwdriver or drill and carefully make holes in place of the bays.
This simple procedure requires accuracy, but allows you not to purchase a new power source, but to restore the functionality of the existing one.
How to make a serviced battery out of a maintenance-free battery
The time comes and the car owner is no longer satisfied with the characteristics of the battery. If you have a sealed battery, do not throw it away and buy a new one. You can make it serviceable if you open the lid in the way we described above. This will allow you to carry out a number of procedures necessary to maintain the health of the power source.
The ability to check and change the electrolyte level is one of the signs of battery serviceability. Closed-type batteries are equipped with an indicator that allows you to see the electrolyte level. Some cases are made of translucent materials or are characterized by the presence of labels, which helps to monitor the amount of solution in all banks. The electrolyte level can be checked using a special tube or syringe by inserting them into the holes made in the lid. The normal amount of solution corresponds to values of 10–12 millimeters of liquid above the plates.
Do not forget that not only the level of acid, but also its density is an important characteristic of battery performance. You can get data on the density of the solution using a hydrometer. Take a syringe, insert it into the hole on the lid and take the electrolyte from the jar. Pour into the hydrometer and see the readings. Too low density (less than 1.22 g / cm3 at temperatures up to +6) does not allow the battery to work fully and indicates a small amount of electrolyte and the need to replenish it. An increased density or insufficient level of the solution requires topping up with distilled water.
Battery hydrometer.
Checking the electrolyte level using a transparent tube.
Please note that an excessive concentration of electrolyte leads to sad consequences - sulfation and destruction of the plates.
The figure shows the density values of the electrolyte under various conditions.
After completion of work on adding water or an acid solution, the holes in the cover must be covered with sealant.
Safety
Attention! A sealed battery contains an acid solution. Contact with unprotected skin may cause burns.
- We strongly recommend using protective equipment when disassembling the power supply. It is strictly forbidden to turn over or shake the jars. This may lead to a short circuit.
- If the battery cover is secured with clasps, be careful not to break them. In case of breakage, the part will have to be glued, and this does not guarantee the safe operation of the power source.
- If you want to split the battery with a tool, choose special tools that will help protect your eyes from fragments.
Is it safe to say that a maintenance-free battery can be made serviceable? Of course, a closed battery can be remade! If the purpose of opening the battery is to extract lead for fishing or hunting, then following a number of precautions, you can easily handle it with just a hammer.
