FAQ


What is sulfation of batteries?

Sulfation is the formation or deposit of lead sulfate on the surface and in the pores of the active material of the batteries' lead plates. If the sulfation becomes excessive and forms large crystals on the plates, the battery will not operate efficiently and may not work at all. Common causes of battery sulfation are standing a long time in a discharged condition, operating at excessive temperatures, and prolonged under or over charging.

How long a battery can last?

The service design life of a battery are vary considerably with how it is used, how it is maintained and charged, temperature, and other factors.

Do batteries self-discharge when not in use?

All batteries, regardless of their chemistry, self-discharge. The rate of self-discharge depends both on the type of battery and the storage temperature the batteries are exposed to. However, for a good estimate, Narada batteries self-discharge approximately 4% per week at 80ĄăF.

How can I evaluate the health and charge state of a battery?

Routine battery examinations divulge irregularities in the charging system as well as in the batteries. The principle method is to examine the electrochemistry of the battery through hydrometric electrolyte inspection. As previously discussed, this important examination cannot be accomplished with sealed absorption or gel batteries. Voltage readings alone require experience to interpret. Hydrometric readings will uncover early warnings of overcharging or overdischarging before batteries are damaged. The state-of-charge and reliability of a lead acid battery can best be determined by the specific gravity of the electrolyte measured directly with a common bulb-type hydrometer with a glass float. We do not recommend the ball float type hydrometer. Specific gravity is a unit of measurement for determining the sulfuric acid content of the electrolyte. The recommended fully charged specific gravity of marine batteries is 1.255 to 1.265 taken at 80ĄăC More than .025 spread in readings between fully charged cells indicates that the battery may need an equalization charge. If this condition persists, the cell is failing and the battery should be replaced. Since water has a value of 1.000, electrolyte with a specific gravity of 1.260 means it is 1.260 times heavier than pure water while pure concentrated sulfuric acid has a specific gravity of 1.835.

Q:What are the hazards of battery over discharge?
When the battery discharge current is large, the heat will become more obvious, there will be serious heat generated when the battery deformation, when the concentration of lead sulfate is particularly large, will form a larger crystal particles, that lead to the battery Internal irreversible sulfation.
Q:What is the difference between a maintenance-free battery and a conventional battery?
Lead-acid battery is composed of positive and negative plates, partitions, shell, electrolyte and wiring pile head and other components, the discharge of the chemical reaction is to rely on positive electrode active substances (lead dioxide and lead) and negative plate active substances (sponge Pure lead) in the electrolyte (dilute sulfuric acid solution) under the action, which plate grid, the traditional battery lead and antimony alloy manufacturing, maintenance-free battery is made of lead calcium alloy, the former with antimony, the latter with calcium, This is the fundamental difference between the two points.
Q:What is the meaning of the battery above 12v65Ah?
12V is said to be the voltage, 65Ah is the current. (A is the unit of current. H is the time unit .1 hours.)
Q:How does the battery increase the voltage?
Chemical energy can be converted into electrical energy device called chemical battery, generally referred to as the battery. After discharge, the internal active material can be regenerated by charging - the electrical energy stored as chemical energy; chemical energy can be converted to electrical energy again when the discharge is required. This type of battery is called a battery (Storage Battery), also known as secondary battery.
Q:What are the advantages of maintenance-free batteries?
Maintenance-free battery using lead-calcium alloy grille, the amount of water generated when charging less water evaporation is low, with the shell with a sealed structure, the release of sulfuric acid gas is also very little, so with the above advantages.
Q:How to determine the battery is good or bad?
If less than 9V but the pointer is in a certain value does not move that the battery is in a state of loss, need to add charge.
Q:What is a maintenanceable battery?
It also has a shock, high temperature, small size, self-discharge characteristics. Life is generally twice the ordinary battery.
Q:How does battery activation work?
If you are talking about dry batteries, that is, to add sulfuric acid can use the battery (commonly known as water bottles), then it is because the long-term storage so that a high degree of oxidation of the negative board, plus acid will be a high temperature, Low, you can add acid in the pool after the addition of a small current for a long time to charge, you can solve. Generally with 0.05C charge to 3 times can be.
Q:What are the technical parameters of the battery?
Usually the capacity of the power supply is expressed by kV · A or kW. However, as a power supply VRLA battery, the use of security (A · h) that its capacity is more accurate.
Q:How is the capacity of the battery defined?
General circuit has a battery protection circuit, once the battery voltage is less than 10.8V will automatically cut off the electricity to prevent the battery because of over-discharge and damage. (Nominal value of 12V battery internal six cell grid) with the battery discharge current multiplied by the discharge time to express how much energy the battery can store, is a very image of a measure. The greater the value of the battery, indicating that the battery can store more energy. But does not mean that the battery can use such a large current discharge.
