Dry-charged battery: description, commissioning, positive aspects

Each element of the car needs careful care, and if it is a question of operating the car in the winter, then special attention is required by the battery. In the cold, its resource is significantly reduced. To be ready at any time to replace a failed source of electricity and go on the road, keep a dry-charged battery on your shelf. It is the most durable and cheap feeder.

Dry-charged battery

Habitual batteries come to the counters in a charged state: the electrolytic solution (sulfuric acid) is already poured into a plastic container with lead plates inside.

Dry-charged batteries come to the market empty. They have a plastic shell with a lead reagent inside them, but they do not contain an acid solution. This solution gives the source of electricity some advantages, most important of which is the possibility of long-term storage.

But before installing a dry-charged battery in a car, it is necessary to bring it into working condition. To do this, you must always have at hand an acid solution and know the specific rules for putting the battery into operation.

Commissioning a dry-charged battery in service

The amount of acid required for charging the battery depends on the type of device purchased. Usually this parameter varies within the limits of 1.5-5 liters. The only thing you can be sure of - you need more acid than the operating volume of the battery.

The first thing to do is to depressurize the plastic sheath. Do this in a clean technical room, because even a small amount of pollutants can ruin the installation. After that, start pouring the electrolyte into a dry-charged battery until the top edge of the plate is under the 2-centimeter layer of the composition.

Without installing the caps, leave the battery for two hours - during this time the lead is impregnated with acid, its volume will decrease, and you will need to fill it again to its original level.

Possible options

Once you have brought the amount of electrolytic solution to a constant level, check the voltage value with a voltmeter. There are several possible options:

1. If the sensor shows 12.5 or more volts, then the battery is ready for use.
2. In the case where the indicator indicates a voltage between 10.5 and 12.5 V, the device must be recharged.
3. When the voltage at the terminals is below 10.5 V, the battery is considered to be damaged.

The first case says that a dry-charged battery is ready for use. Commissioning was successful, and it remains only to put the battery in the car. The second option tells us that to use the battery it is necessary to recharge it, and the last one - that the conditions of storage or manufacture have been violated, the device is not suitable for operation.

Recharging a dry battery

To recharge a half-ready battery, you will need two devices: an electric current rectifier and a hydrometer, a device that measures the density of the electrolytic solution.

To avoid any problems with how to charge a dry battery, follow the plan:

1. Connect the charger to the terminals, do not forget about the polarity.
2. Turn the device on and set the charging current to 10% of the battery power.
3. Continue charging the battery for 5 hours.
4. Check the battery voltage, and if it still does not reach the 12.5 V mark, lower the power halfway and charge another 4 hours.

To understand that the battery is ready to work, you can and in other ways. Firstly, in the ready-for-use state, the electrolyte, filled in a dry-charged battery, starts to boil. Secondly, the density of the solution and the voltage on the device will be at the same level constantly. When none of the conditions are met, the device still needs recharging.

Advantages of dry-charged batteries

Despite the complexity of putting the dry-charged battery in service, it enjoys considerable popularity due to its advantages. The first of these is a long shelf life. Conventional lead-acid batteries are stored for no more than 4 years and require special conditions. "Dry" plants retain their properties for 7 years and do not need additional storage conditions.

The second advantage is the ease of transportation. In the non-operating state, there is no electrolyte in it, which can begin to flow for some reason. In addition, such a device is light in weight.

The third advantage is the cost of having a dry-charged battery. Putting it into operation with your own hands will cost around 300 rubles, and the average price of the battery itself starts to grow from 1900 rubles, which is much lower than the finished batteries.

Rules for the operation of dry-charged batteries

Substantially to prolong the service life of dry-charged energy sources ready for operation can be observed by elementary operating rules. First, you will need to check the voltage at the terminals once a month in the "idle" state and under load.

At the same time, measure the density of the electrolyte - it should not fall below the regulated level. If necessary, recharge the battery in accordance with the instructions.

Secondly, every six months, arrange a battery training - discharge to the minimum value, and then completely replenish its power reserve. Finally, to use dry-charged batteries lasted as long as possible, use a battery with a stabilized voltage - it fills the battery in a gentle mode.
