- 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: What are the hazards of battery over discharge?
- The battery discharge to the standard termination voltage when the internal resistance will become larger, the battery electrolyte concentration will become very thin, especially the battery plate micropores and battery plate surface these two points are almost neutral; battery over discharge because of Internal resistance will become larger, so the battery will appear inside the phenomenon of heat, the battery volume will appear fever expansion.
- Q: What battery does the van use?
- The battery is mainly composed of tube positive plate, negative plate, electrolyte, separator, battery compartment, battery cover, pole, injection liquid cover and so on. The electrode of the exhaust type battery is made of lead and lead oxide, and the electrolyte is an aqueous solution of sulfuric acid. The main advantage is the voltage stability, the price is cheap; the disadvantage is lower than the energy (that is, per kilogram of battery storage power), short life and routine maintenance frequently. Old ordinary battery life of about 2 years, and the need to regularly check the height of the electrolyte and add distilled water. However, with the development of science and technology, lead-acid battery life becomes longer and maintenance is also more simple.
- Q: What is the meaning of the battery above 12v65Ah?
- 12V is said to be the voltage, 65Ah is the current. (A is the unit of current. H is the time unit .1 hours.)
- 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 does the battery increase the voltage?
- Chemical energy can be converted into electrical energy device called chemical battery, generally referred to as the battery. After discharge, the internal active material can be regenerated by charging - the electrical energy stored as chemical energy; chemical energy can be converted to electrical energy again when the discharge is required. This type of battery is called a battery (Storage Battery), also known as secondary battery.
- Q: What is a maintenanceable battery?
- 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.
- Q: Battery 200ah / 104 what does that mean?
- This should be refers to 2V200AH battery 104, power with the 220V.
- 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.
