 Beijing China the Keya Flying Technology Co., Ltd. 
 Beijing China the Keya the Flying Technology Co., Ltd. after the lead-acid batteries by adding electrolyte, the temperature rises what is the reason? 
 New battery to the electrolyte, the temperature rise associated with the new battery and internal factors. Dry charged battery fluid temperature, battery temperature is not very clear, this is because the dry-charged plates through anti-oxidation treatment, the factory battery is fully charged state, plus the liquid you can load; plate battery, without the antioxidant treatment, the negative plates in a fully charged state, a considerable part of the material is to generate a lot of heat for the lead oxide and sulfuric acid reaction, so long high temperature. Sometimes the summer temperature of 50 ℃, the charge should pay attention to the artificial cooling. 
 26 constant pressure limiting VRLA battery charge, and how to determine the battery is fully charged? 
 Two based on: 1) the charging time of 18 to 24 hours (non-deep discharge can be shorter, such as the 20% depth of discharge of the battery, charging time can be shortened to 10 hours). 2) the charge current drops to the minimum three hours remain unchanged. 
 27 produce What are the causes of plate sulfation.? 
 Produce plate sulfation the following reasons: 
 1) Battery charging less than the beginning or the beginning of charging interrupt a long time; 
 2) Battery charge long enough; 
 3) after discharge, failure to charge; 
 4) often overcharge or current deep discharge; 
 5) the electrolyte density is too high or the temperature is too high, the lead sulfate in-depth formation difficult to restore; 
 6) The battery holds a longer time not used for long without periodic charging; 
 7) electrolyte impurities, self-discharge; 
 8) the local effects of an internal short circuit or battery surface water caused by leakage; 
 9) Battery internal electrolyte liquid, so that the plate and exposed parts of sulfuric acid. 
 28 battery storage requirements? 
 Requirements of a well-ventilated, dry (preferably mounted air conditioning), keep the ambient temperature around 25 ℃; ground bearing capacity; to conduct additional power after storage for 3 months.
