Lead-acid batteries and lead oxide on human nervous system, digestive system, blood system and kidneys to a certain extent, is usually best not to waste battery anatomy. Please note the time required to dissect the protection and guidance staff.
12、After the absorption of lead poisoning, how to treat?
After the absorption of lead poisoning treatment agencies should enter the professional treatment of persons engaged in lead exposure in diet can be more drinking milk, soy milk and other help lead out of the body.
13、What are the common types of battery slot?
Common battery slot with hard rubber and polypropylene, automobiles, motorcycles, traction battery slot, ABS sealed battery compartment, and made a small amount of polystyrene battery compartment.
14、What are the common battery separator?
Common battery separator rubber diaphragm, PP partitions, PE partitions, PVC partitions and the AGM separator.
15、Whether daily consumption of pure water can be used for battery use?
Can not be applied because of the daily pure water that people drink their water impurities is much higher than batteries required, just water, some elements of the sediment bacteria beneficial to humans and less. Battery water should reach JB/T10053? 1999 standards.
16、Manufacturing lead-acid batteries commonly used alloys are those?
The alloy used to make lead-acid batteries are mainly lead-antimony alloy, lead antimony alloy lower, lead-antimony alloy and lead-calcium cadmium alloy.
17、What lead-acid battery charging method?
There are constant current charging, constant voltage charging, constant current voltage limited charging, equalizing charge, floating charge and the pulse fast charging.
18、Lead-acid battery electrolyte density and open circuit voltage have anything to do?
Open circuit voltage = 0,85 + electrolyte density (empirical formula)
19、Plate lead-acid battery capacity depends on what?
Depends on positive and negative plate active material.
20、What is the main components of lead-acid battery positive and negative plates?
Major components of positive plate active material is lead dioxide, the main component negative electrode active material is sponge lead.
21、Why lead-acid battery charging fever?
Battery charging process, the energy into chemical energy part, but also use some energy into heat energy and other. HP Pavilion dv9000 Battery heat is normal, but high temperatures should be checked in time when the charge current is too large or internal short-circuit the battery, etc., heat, and the electrolyte volume is less, in the case of less sealed battery electrolyte resistance increases when will cause the battery temperature and charging students a high voltage.
23、Why lead-acid battery charging pungent smell?
Battery charging process, battery acid inside the steam generated, steam, hydrogen and oxygen mixed material escaped into the air, will give the impression Road, irritating odor.
24、What is a lead-acid battery float charging, equalizing charge?
Float Charging: When the normal power supply interruption to the circuitry of the battery. The terminal is always connected to the constant voltage power supply to maintain the battery fully charged state is close. Equilibrium charge: To ensure that all single battery fully charged battery charge of a continuation.
25、After the new lead-acid battery electrolyte added, why the temperature rise?
Adding new battery electrolyte, the temperature rise with a new battery internal factors. After the dry-charged battery fluid temperature rise increases the battery temperature is not very clear, this is because dry charged plates through anti-oxidation treatment, the factory battery is fully charged state yes, plus you can load after the use of liquid; ordinary plates batteries, without the antioxidant treatment, negative plates in a semi-fully charged state, a considerable part of the material is lead oxide and sulfuric acid reaction to produce large amounts of heat, so long high temperature. Sometimes the summer temperature reaches above 50 ℃, the charge should pay attention to artificial cooling.
26、Constant pressure limiting manner VRLA battery charge, how to determine the battery is fully charged?
There are two basis: 1) the charging time of 18 to 24 hours (non-depth of discharge can be shorter, such as the 20% depth of discharge of the battery, charging time can be shortened to 10 hours). 2) the minimum charge current reduced to 3 hours and continuous change.
27、What causes sulfated plates?
Sulfated plates produced for the following reasons:
1) The initial charging the battery charge insufficient or early interruption longer;
2) Battery charge long enough;
3) failure to charge after discharge;
4) often overcharge or deep discharge a small current;
5) electrolyte density is too high or temperature is too high, the formation of lead sulfate will not recover in depth;
6) The battery holds a longer time, not used for long without periodic charging;
7) electrolyte impurities, large self-discharge;
8) The local effects of the internal short circuit or the battery more than surface water caused by leakage;
9) The liquid electrolyte within the battery is low, so that the exposed part of the sulfation plate
28、Battery storage requirements?
Required good ventilation, dry (preferably mounted air conditioning), to keep the ambient temperature around 25 ℃; stronger ground bearing capacity; storage after 3 months to conduct additional power.
29、What causes the battery leakage and how to solve?
Reason:
a) sealant for sealing cracks caused by the aging;
b) severe overcharge the battery, mix different types of batteries, PA3399U-1BAS Battery gas recombination efficiency is poor; c) when the acid spilled acid irrigation, resulting in false leakage.
Solution:
1) may be false wipe the battery leakage, left latter observation;
2) the replacement of leaking batteries.
30、Found on the capacity of detecting less than the capacity of the battery packs,What should do?
1) The entire group should do both the battery charging process, that are full 18-24 hours.
2) or with a single machine to the battery charge to add a separate power.
