 FAQ of Solar Battery REX Series

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.

What is battery cycle life?

One cycle of a battery is a discharge from full charge to full discharge and a return to full charge again. The total number of cycles a battery can perform before failure is called its Cycle Life. Moat battery manufacturers will not discus the Cycle Life of their product. Many advertised Deep Cycle batteries have not been tested, or, which is the case with cranking batteries, were never designed for long Cycle Life .

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:How should the battery be well maintained?
Voltage check the state of the battery standard voltage should be maintained between 12.2 ~ 12.7V. If the voltage is too low should be charged, the charge should be kept small charge for a long time. Battery charging need to use a professional charger, the owner will not try to charge their own, the owner can only keep the engine running on the battery can be charged. If the battery aging should be replaced.
Q:How to repair the battery?
Charge the battery at constant voltage. It is the beginning of the time, using 0.1C ~ 0.25C current charge, to 16.2V later, by reducing the current method to maintain the charging voltage, until the charge current drops to 0.03C when the stop charging.
Q:Battery 200ah / 104 what does that mean?
This should be refers to 2V200AH battery 104, power with the 220V. Lead-acid battery nominal voltage is 2V / (each or monomer), but in fact will be higher than 2V, so the actual use and charging equipment for the matching will use 104, also useful 103, also useful 108 Only.
Q:Lead-acid battery how to maintain?
Open the rubber cap, exposing the exhaust raft, you can see the battery inside, some of the battery exhaust cutting can be unscrewed.
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.
Q:What are the hazards of battery over discharge?
Crystalline conductivity is poor, and bulky, will clog the pores of the battery plate, affecting the battery electrolyte penetration and exchange, but also further increase the battery resistance, a long time will prevent the battery power and chemical energy Of the reversible conversion, resulting in poor recovery of the battery charge, the battery was seriously damaged, or even unable to repair until scrapped.
Q:What is a maintenanceable battery?
Maintenance-free battery due to its own structure on the advantages of electrolyte consumption is very small, in the life of the basic need not add distilled water.
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 kind of battery is divided into?
Ordinary battery: ordinary battery plate is composed of lead and lead oxide, the electrolyte is sulfuric acid aqueous solution. Its main advantage is the voltage stability, the price is cheap.
