FAQ

Yes, we are a professional battery manufacture in Guangdong Province, China. And we produce plates by ourselves.

Primary batteries are ordinary dry batteries and can only be used once. Secondary batteries are also called rechargeable batteries. Power batteries (or traction batteries) in secondary batteries are currently the main power source for electric vehicles.

The capacity of the battery refers to the amount of electricity that the active material in the battery can participate in the electrochemical reaction is called the capacity of the battery, that is, the amount of charge that the battery can hold after charging. The unit is "Ah" (Ah) and 1 A (A). The current is discharged for 1 hour, and the capacity is 1 ampere hour (Ah). Assuming that the average current is 4A, the discharge time is 3 hours when the battery is discharged at the termination voltage of the battery, and the battery capacity is 12Ah (the discharge is not calculated here) effectiveness).

The rated capacity of a battery refers to the requirements for designing or manufacturing a battery when it is specified or guaranteed that the battery should discharge a minimum amount of power under certain discharge conditions. The battery capacity indicated by the manufacturer refers to the amount of power that the battery should provide when the battery is discharged to the termination voltage at a rate of 10h at an ambient temperature of 25 C. The unit is Ah (ampere * hour).

According to the amount of active material contained in the battery, the capacity of the battery calculated from electrochemical theory is called the design capacity.

The actual capacity of the battery refers to the actual amount of electricity discharged by the battery under a certain discharge condition, which is mainly affected by the discharge rate and temperature (so strictly speaking, the battery capacity should indicate the charge and discharge conditions).

Under the specified charging voltage and current conditions, the amount of charge the battery accepts per unit time.

After the battery is charged, the phenomenon that the capacity decreases by itself during storage is called self-discharge, also known as the charge retention ability, which refers to the ability of the battery to maintain the amount of electricity stored under certain conditions when the battery is open. Measuring the percentage of battery self-discharge to the total capacity over a certain period of time is called "self-discharge rate".

It refers to the resistance to the current flowing through the battery when the battery is working. There are two parts: ohmic internal resistance and polarization internal resistance. Large internal resistance of the battery will cause the battery's discharge working voltage to decrease and shorten the discharge time. The internal resistance is mainly affected by the battery material, manufacturing process, battery structure and other factors. Is an important parameter to measure battery performance.

There are many unfavorable factors to the battery, which mainly occur during the charge and discharge stage. 1. The "second super" discharge phase is mainly the discharge current overvalue, that is, the discharge exceeds the allowable current value for a long time; the second problem of discharge is overdischarge, that is, exceeding the allowed discharge amount of the battery, called "second super", which is very harmful to the battery life .2. The charging stages of "two passes" and "two owes" are "two passes" and "two owes".(1) "Two passes": One pass is overcharging; one pass is lead-acid batteries that have been stored for an extended period of time without being used, and are replenished from time to time.(2) "Two shortfalls": One shortfall is due to undercharging of lead-acid batteries. The batteries are often not fully charged, and the plates cannot be restored in time after vulcanization, which is extremely taboo for lead-acid batteries; The underbalance between them causes the difference between the discharge level and the charge level of each single battery in a group of batteries to widen, the more the undercharge becomes the more undercharge and the overdischarge becomes the more overdischarge. Affect the life of the entire battery pack, but also increase their own economic expenses."Two passes" and "two owes" are the enemies of the battery, not to be underestimated. However, the "two passes" and "two owes" are caused by people themselves, and the problems are more complicated. There are many reasons, from selection, maintenance, reasonableness of the matching of controllers and chargers, and timely causes of battery failure Detection, etc., they are interconnected.

It cannot be used, because the pure water that people drink everyday has a higher impurity content than the battery water requirements, but some elements in the water are beneficial to the human body and less bacterial sediment. Battery water should meet JB / T10053-1999 standard requirements.

No.

We Adopt ISO 9001 quality system to control the quality. We have Incoming Quality Control (IQC) department to test and confirm raw material meets high quality producing requirements, Production Quality Control (PQC) department contains The first Inspection, In-process quality control, acceptance inspection and full inspection, Outgoing Quality Control (OQC) department confirm no defective batteries come out from the factory.

It depends on battery capacity, depth of discharge, and battery usage. Please kindly contact us for accurate information based on detailed requirements.

Each battery has the capability of electrochemical conversion, that is, the stored chemical energy is directly converted into electrical energy. As far as a secondary battery (also called a battery) (another term is also called a rechargeable portable battery), In the process, chemical energy is converted into electrical energy; in the charging process, electrical energy is converted into chemical energy again. This process can be charged and discharged more than 500 times, depending on the electrochemical system.

It is necessary to pay attention to insulation; because the battery leaves the factory with liquid charge, it should prevent the danger of short circuit or electric shock due to improper operation.

Colloidal batteries are recognized internationally by using gel-specific separators (PVC, PE, phenolic resin, etc.) as true colloids, and AGM separators as false colloids are not recognized internationally. The definition of true and false colloids still depends on the amount of silica added. The amount of silica used for colloidal separators is more than 5%, and AGM separators exceeding 1.5 are difficult to add.

A loose connection will cause the resistance at the connection to increase, which will easily cause sparks during charging and discharging. In severe cases, it will cause heat and fire, and an accident will occur.

About 7 days for stock products, around 25-35 days bulk order and 20ft full container products.

You may have heard it said "you need a 3 stage charger". We've said it, and we'll say it again. The best kind of charger to use on your battery is a 3 stage charger. They are also called "smart chargers" or "micro processor controlled chargers". Basically, these types of chargers are safe, easy to use, and will not overcharge your battery. Almost all of the chargers we sell are 3 stage chargers. Okay, so it's hard to deny that 3 stage chargers work and they work well. But here's the million dollar question: What are the 3 stages? What makes these chargers so different and efficient? Is it really worth it? Lets find out by going through each stage, one by one.

Sealed lead acid battery life is determined by many factors. These include temperature, depth and rate of discharge, and the number of charges and discharges(called cycles).

Reserve capacity is the number of minutes a battery can maintain a useful voltage under a 25 ampere discharge. The higher the minute rating, the greater the battery's ability to run lights, pumps, inverters, and electronics for a longer period before recharging is necessary. The 25 Amp. Reserve Capacity Rating is more realistic than Amp-Hour or CCA as a measurement of capacity for deep cycle service. Batteries promoted on their high Cold Cranking Ratings are easy and inexpensive to build. The market is flooded with them, however their Reserve Capacity, Cycle Life (the number of discharges and charges the battery can deliver) and Service life are poor. Reserve Capacity is difficult and costly to engineer into a battery and requires higher quality cell materials.

All sealed lead acid batteries self-discharge. If the capacity loss due to self-discharge is not compensated for by recharging, the battery capacity may become unrecoverable. Temperature also plays a role in determining the shelf life of a battery. Batteries are best stored at 20℃. When batteries are stored in areas where the ambient temperature varies, self-discharge can be greatly increased. Check the batteries every three months or so and charge if necessary.

The capacity of a battery, in Ahs, is a dynamic number that is dependent on the discharge current. For example, a battery that is discharged at 10A will give you more capacity than a battery that is discharged at 100A. With the 20-hr rate, the battery is able to deliver more Ahs than with the 2-hr rate because the 20-hr rate uses a lower discharge current than the 2-hr rate.

The newer type of sealed non-spillable 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. Just like the Gel batteries, the AGM Battery will not leak acid if broken.

A gel battery design is typically a modification of the standard lead acid automotive or marine battery. A gelling agent is added to the electrolyte to reduce movement inside the battery case. Many gel batteries also use one way valves in place of open vents, this helps the normal internal gasses to recombine back into water in the battery, reducing gassing. "Gel Cell" batteries are non-spillable even if they are broken. Gel cells must be charged at a lower voltage (C/20) than flooded or AGM to prevent excess gas from damaging the cells. Fast charging them on a conventional automotive charger may be permanently damage a Gel Battery.
