- Q: How to determine the battery is good or bad?
- General side maintenance has an observation hole if it is green to prove that the battery is normal if it is black to prove that the battery does not save electricity. There is to observe whether there is liquid exudation, if any, proved to be bad. Finally, you can touch the hand, such as feeling the battery around the plane has proved proof bad.
- Q: How to deal with waste batteries?
- Laboratory recycling method: ordinary dry battery is cylindrical, the outer cylinder made of zinc, the zinc cylinder is the battery negative; tube central carbon rod for the positive; tube for the manganese dioxide, ammonium chloride and chlorination Zinc.
- Q: Maintenance-free battery how to detect it?
- Do not always check the color of the electric eye for maintenance-free batteries. Green for the full power; black for the lack of electricity, need to be added to charge; gray or light yellow for the electrolyte is insufficient, because maintenance-free battery can not add liquid, should immediately replace the battery.
- 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?
- 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: What is the meaning of the battery above 12v65Ah?
- 12V represents the rated voltage. 65Ah indicates that the battery capacity (ie 1 ampere current can be used for 65 hours).
- Q: How should the battery be well maintained?
- Voltage check the state of the battery standard voltage should be maintained between 12.2 ~ 12.7V. If the voltage is too low should be charged, the charge should be kept small charge for a long time. Battery charging need to use a professional charger, the owner will not try to charge their own, the owner can only keep the engine running on the battery can be charged. If the battery aging should be replaced.
- 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: 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: Lead-acid battery how to maintain?
- After 5 hours of repair, the excess electrolyte is sucked out with a straw, and if the electrolyte is sucked out into black, it indicates that the battery is severely grounded and that the battery is difficult to repair.
