  • Maximum operating  temperature range -40oC to 50oC(-40oF to 122oF)

  • A separate battery room is  not necessary

  • Reduced maintenance no water  addition required.

  • Design float life: 20 years at 25oC (77oF)

Solar Battery REX Series Construction

  • Positive plate --- Reinforced grids in a corrosion-resistant pure  lead, high tin, low calcium alloy

  • Negative plate --- Lead-calcium alloy grid

  • Separator ---  High  density microporous glass mat with low electrical resistance

  • Container & lid --- High strength ABS(HB). Optional flame retardant F V-0 and halogen-free versions available

  • Electrolyte --- Sulphuric acid with a density of 1.28g/ml  absorbed in AGM

  • Terminal design --- Patented leak resistant seal configuration with  brass insert

  • Safety valve --- Calibrated opening pressure , the valve  equipped with flame arrestors for  increased operational safety and service life.


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:How to deal with waste batteries?
In addition to lead-acid batteries, all kinds of batteries are dissolved in sulfuric acid, and then by means of ion resin from the solution to extract a variety of metals, raw materials obtained in this way than the heat treatment method is pure, so the market price is higher, and the battery contains 95% of the various substances can be extracted.
Q:What is the difference between a maintenance-free battery and a conventional battery?
As a result of maintenance-free batteries using lead-calcium alloy grille, the amount of water generated when charging less water evaporation, coupled with the shell with a sealed structure, the release of sulfuric acid gas is also very small, so it compared with the traditional battery, With no need to add any liquid, the wiring pile head, wire and body corrosion less anti-overcharge capacity, starting current, power storage time is long, by the car people welcome.
Q:How to repair the battery?
Maintain the battery before, first of all to clean up the battery appearance of the dust, remove the terminal above the stain and corrosion.
Q:The role of the battery?
Battery is widely used, can be used for ups, electric cars, scooters, cars, wind energy solar systems, security, and so on.
Q:What are the advantages of maintenance-free batteries?
Maintenance-free battery because of its normal charging voltage, the electrolyte only produce a small amount of gas, so throughout the use of the need for the addition of distilled water, in the normal charging system, do not need to remove the charge from the removal. But in the maintenance of the proportion of its electrolyte should be checked.
Q:How to determine the battery is good or bad?
Observe the battery electrolyte is turbid, turbidity that the battery positive plate softening. Observe the bottom of the battery whether there is sediment, if the plate off the battery capacity has been inadequate. Hand hit the battery two electrode piles If you hear an empty voice that pole pile and plate break. With a thick wire short-circuit positive and negative pile observation of the battery filling holes, such as the discovery of a bubble appears that the interval has been damaged.
Q:What is a maintenanceable battery?
This is relative to a maintenance-free battery. Maintenance of the battery needs to be supplemented with electrolyte to ensure work, while maintenance-free is not required.
Q:80ah how much battery storage capacity?
0AH storage is 80AH ah If the actual storage capacity will have to see the brand. I have seen 100AH only 24 pound. This is not even 60AH.
Q:What are the technical parameters of the battery?
The main performance parameters of the battery are the following: model; voltage; battery capacity; battery type, such as lead-acid batteries, alkaline batteries, lithium batteries, solar cells, fuel cells.
Q:Maintenance-free battery how to detect it?
Check the height of the electrolyte at least once a month. There is no mark line of the battery, the electrolyte added to the plate 10-15mm can be higher; there are two red line of the battery, the electrolyte can not exceed the red line above.
