Is there so much to be said for car batteries? Maybe the battery will be scrapped

Batteries are an important part of your car, providing electricity for starting, lighting, audio and other appliances. There are two common types of batteries on the market: conventional batteries and maintenance-free batteries.lithium battery cell machine So what's the difference between maintenance-free batteries? Will there be less electrolyte? Can you add more water? Today, we're going to take a look at these questions.

First let's take a look at how maintenance-free batteries work. Maintenance-free batteries are sealed lead-acid batteries that use special designs and materials to minimize the evaporation and consumption of water inside the battery, thus eliminating the need to add distilled water or electrolyte on a regular basis. There are two main forms of maintenance-free batteries:one is a dry maintenance-free battery, using glass fiber partitions to adsorb and fix the electrolyte, so that there is no free liquid inside the battery; the other is a colloidal maintenance-free battery, which uses silica gel or lead sulphate colloid to solidify and stabilize the electrolyte, so that the battery internal formation of a jelly-like substance.

Next, let's look at the advantages and disadvantages of maintenance-free batteries. Maintenance-free battery compared to other ordinary batteries have the following through several major advantages: First, you can use the network life time is longer,car battery manufacturers because there is no water evaporation and consumption of a large number of reductions, resulting in corrosion of the pole plate and sulfate crystals to reduce the battery's validity; Second, to improve the safety of a higher, because of the sealing of the structure can prevent the acid spillage and gas leakage, thus reducing the information explosion and corrosion Thirdly, the working performance is more stable, because the constant change of ambient temperature has less influence on the battery, which ensures the efficiency of the battery's discharging and charging technology.

However, maintenance-free batteries also have the following disadvantages: due to the use of special design and materials, the battery price is higher, resulting in higher production costs;battery coating due to the use of partition or gel to occupy a portion of the space, the battery capacity is smaller, resulting in a reduction in the effective capacity; due to the sealing of the structure can not be opened and checked, resulting in failure can not be repaired, the three batteries can not be repaired.

The evaporation and consumption of water in maintenance-free batteries is very small, which can basically meet the needs of the entire service life. If you force open the cover or hole plug of the maintenance-free battery and add distilled water or other liquids, it will destroy the sealing and balance of the battery, leading to performance degradation or damage. Therefore, maintenance-free batteries do not need to add water and electrolyte.
