The electrolyte concentration test of the battery is the key to detect the key in the field of lead-acid batteries, in particular the water-acid battery, the density of the single-bit specific gravity, often can determine the good or bad of the battery, or different styles, and the battery of the factory. There is a certain difference between the density in electrical conditions, and the section 1.26-1.295.1, specific gravity determination
When the measurement is measured, the electrolyte is slowly suiled into the outer cylinder using a suction type proportion to observe the scale of the buoy.
The electrolyte specific gravity of the lead battery will vary with temperature, the specific gravity of the electrolyte is 20 degrees at 20 degrees Celsius, so the proportion of the gravity must be converted to the standard specific gravity at 20 ¡ã C. When the temperature change 1 ¡ã C, the specific gravity changes 0.0007, so, while the measurement is measured, the temperature must be measured, and the temperature is measured, use a rod-shaped alcohol thermometer.
The specific gravity measured when the temperature T ¡ã C is ST, then the specific gravity S20 is converted at the standard temperature of 20 ¡ã C.
S20 = ST + 0.0007 (20-T)
S20 .. is a specific gravity of converting 20 ¡ã C
ST .. The proportion measured at T ¡ã C
T .. . to measure the actual Celsius temperature of the electrolyte
For example: 20 ¡ã C is 1.280, at 10 ¡ã C to 1.273; 30 ¡ã C, becomes 1.287
2, add pure water
When discharge is repeated, the electrolytic liquid surface will slowly decrease, so regularly check the electrolyte liquid level, supplement pure water at any time to maintain the appropriate level. If it is ignored by ignoring, the polar plate is exposed, the electrolyte is increased, and a chain reaction such as battery vulcanization is damaged.
3, non-fluidity and battery life in the electrolyte
In the electrolytic solution contain nitric acid, hydrochloric acid, sulfuric acid, salt, organic matter, etc., will corrode the plate to speed up the battery life, and will also speed up self-discharge, in addition, copper, nickel, iron, manganese will harm the battery Self-discharge increases.
When the battery is hydrated, you must use pure water. When rinsing the battery with water, it is necessary to cover the battery cap to avoid flushing water into the battery.
4. Disadvantages caused by excessive hydration
If it exceeds the highest liquid level, it will occur when charging, and the dilute sulfuric acid ingredient is lost, corroded the battery case, and the electrolyte proportion is low, and the storage capacity is insu Recommend: LiFePO4 Battery Manufacturer Energy storage battery Manufacturer Integrated machine energy storage battery series Manufacturer Lead lithium battery Manufacturer Outdoor Backup Battery Manufacturer Portable outdoor power supply Manufacturer Power battery Manufacturer Powerwall LiFePO4 Battery Manufacturer Battery rack Manufacturers Telecom LiFePO4 Battery Manufacturer Wall mounted battery storage Manufacturer China Lifepo4 Battery
