Q:How should the battery be well maintained?
Electrolyte density This is to evaluate whether the battery charge is normal, whether the aging of the important parameters, the use of density meter or electrolyte density tester can be measured. If the electrolyte density is too small, you need to charge. And the electrolyte concentration is too thick or too thin to a certain extent, it means that such as the occurrence of plate vulcanization, short circuit or overcharge phenomenon, this time on the need for maintenance.
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:The role of the battery?
It filled with lead plate filled with sponge lead as a negative electrode, filled with lead dioxide lead dioxide as a positive electrode, and with 22 to 28% dilute sulfuric acid as electrolyte. In the charge, the electrical energy into chemical energy, the discharge of chemical energy and into electrical energy.
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:How does the battery increase the voltage?
You can use the same battery in series, with 5 12v battery in series becomes 60v, if you need the current is relatively small, you can use DC-DC module to 12v voltage rise to 60v.
Q:What battery does the van use?
General use of lead-acid batteries. Electrode is mainly made of lead and its oxide, the electrolyte is a sulfuric acid solution of a battery. English: Lead-acid battery Discharge state, the main component of the cathode is lead dioxide, the main component of the negative lead; charge state, the main components of the positive and negative are lead sulfate. Divided into exhausted batteries and maintenance-free lead-acid batteries.
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: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: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.
Our pioneering efforts have earned us 10 national patents so far. In fact, we have the second largest number of patents among listed suppliers in mainland China.We also been offering complete solutions for LiFePO4 battery pack buyers for over six years. Customers especially enjoy our battery pack, battery management system and charger solution.
