All battery packs are separated by groups: served elements, minimal products, maintenance products. A significant part of modern modes of transport is equipped with maintenance-free devices, so the owners are asked about what service life they have, whether there are distinctive features in principle work and so on.

Traditional battery require control from the owner itself and master, you need to charge them constantly, as well as to top up distilled water. If you neglect the need to perform these operations, the battery quickly becomes unfit.

Unnwided car batteries are hermetically sealed, so water consumption is reduced to a minimum.

Advantages of elements

Given the main technical parameters of these elements, you can detect several positive properties:

• for full operation of the battery, only recharging is required;
• models can work, regardless of their current and main position;
• batteries are capable of producing a large number of current;
• the service life at proper use is quite long.

Types of devices

Typically, units that are not subject to maintenance are produced in two varieties:

• Hybrid devices - allow negative electrodes, suggest using calcium. If you need to get positive particles, antimony, lead is used.
• Calcium elements - production based on calcium and lead alloy. Compared to other elements, it is more expensive, and their service life is increased.

Disadvantages of non-maintained AKB

The main minus is the impossibility of controlling the electrolyte and add distilled water.

Despite the small amount of disadvantages of this type of devices, they should be allocated and noted on mandatory.

1. Regarding the served models they have a higher price.
2. Low temperatures have a negative impact on their performance and service life.
3. If a faulty electrical equipment is observed in the car, then the service life is instantly reduced, devices can quickly fail.

What is important to know

If you want the life of your products to be as long as possible, then a number of nuances are needed during the operation of the models. Unsuitability of devices to repair requires increased attention from the driver to the state of the car as a whole.

Basic rules for use of uniteduized aggregates:

• At low temperatures in the aggregates, the charge is reduced to zero, so if you often use a car during frosts, you can reduce their service life. To troubleshoot, it is recommended to make the engine start process easier, observing the norms.
• Considering the impact on the state of the electrical equipment of the car's electrical equipment, it is necessary to constantly monitor the fact that the generator worked, there was no leakage.
• Make sure that the battery terminals are clean, otherwise, if the device is poorly fixed, it will significantly reduce its service life and cause premature failure.
• Elements can freely remain in the discharged state, and to eliminate destruction it is necessary to provide periodic recharging.
