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: 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 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: How to deal with waste batteries?: The old battery is ground and then sent to the furnace for heating, then the volatile mercury can be extracted, the temperature is higher when the zinc is also evaporated, it is also precious metals. Iron and manganese fusion after the steel to become the required ferromanganese alloy.

Q: Maintenance-free battery how to detect it?: Battery pole Pole terminal has corrosive material without treatment, as long as no loose on it. If the appearance of the corrosive material, the inner surface of the terminal will also be corrosion, resulting in increased resistance, affecting the normal battery charging and discharge, it must be promptly processed.

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: What are the advantages of maintenance-free batteries?: The advantage of a maintenance-free battery is that the service life is twice as long as the dry battery! And in the use of the process without maintenance! The voltage is also relatively stable.

Q: 80ah how much battery storage capacity?: Is 80AH. Understood to discharge at 80 amps for about 1 hour (but not to say that after 1 hour is finished, there is still electricity). In theory, this is your battery power.

Q: What kind of battery is divided into?: 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. It also has a shock, high temperature, small size, self-discharge characteristics of the general life is generally ordinary Twice the battery. There are two kinds of maintenance-free batteries on the market.

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.
