FAQ

What is a AGM (Absorbed Glass Mat )Battery?

The newer type of sealed nonspillable maintenance free valve regulated battery uses "Absorbed Glass Mats", or AGM separators between the plates. This is a very fine fiber Boron-Silicate glass mat. These type of batteries have all the advantages of gelled, but can take much more abuse. These are also called "starved electrolyte.Ąą Just like the Gel batteries, the AGM Battery will not leak acid if broken.

What are the advantages of the AGM battery?

The advantages of AGM batteries are no maintenance, sealed against fumes, hydrogen, leakage, or non-spilling even if they are broken, and can survive most freezes. AGM batteries are "recombinant" ¨C which means the Oxygen and Hydrogen recombine inside the battery. These use gas phase transfer of oxygen to the negative plates to recombine them back into water while charging and prevent the loss of water through electrolysis. The recombining is typically 99+% efficient, so almost no water is lost. Charging voltages for most AGM batteries are the same as for a standard type battery so there is no need for special charging adjustments or problems with incompatible chargers or charge controls. Since the internal resistance is extremely low, there is almost no heating of the battery even under heavy charge and discharge currents. AGM batteries have a very low self-discharge rate (from 1% to 3% per month). So they can sit in storage for much longer periods without charging. The plates in AGM's are tightly packed and rigidly mounted, and will withstand shock and vibration better than any standard battery.

Q:What are the hazards of battery over discharge?
Excessive discharge can seriously damage the battery's electrical performance and cycle life.
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:What is the meaning of the battery above 12v65Ah?
Voltage 12V, current 65AH, that is the capacity of 65A. (A is the unit of current. H is the time unit)
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: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:How does battery activation work?
Always keep the battery surface clean. Found that the surface of dust and acid, it should be timely wipe, wipe can be wiped with soda water wipes wipe again, after rinse with water.
Q:80ah how much battery storage capacity?
The size of the battery storage power refers to the battery capacity. Battery capacity is generally calculated in AH (safety). You 80Ah battery capacity is 80Ah, meaning that if you discharge current to 80A, you can put an hour.
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.
Q:What kind of battery is divided into?
At present, we used the car battery is divided into three categories, namely, ordinary batteries, dry batteries and maintenance-free batteries three.
