Weak current College】 【battery types and the correct use and maintenance of】.

<br> <br> At present, we commonly used vehicle storage battery is mainly divided into three categories, namely normal batteries, dry charged batteries and battery. <br> Ordinary batteries; ordinary batteries plate is made of lead and lead oxide, the .electrolyte is an aqueous solution of sulfuric acid. <br> Its main advantage is voltage stability, price; the disadvantage is the low specific energy (ie per kg of batteries stored power), the short life and daily maintenance frequently. <br> Dry .charged battery: its name is dry-charged battery, its main characteristic is the negative plates have higher storage capacities, in completely dry conditions, within two years, save the resulting electricity, when used, simply join the electrolyte, etc have 20-30 .minutes. <br> Maintenance-free battery: maintenance-free battery because of its structural strengths, electrolyte consumption is very small, in the use of the life of basic does not require supplementary distilled water. It also has the seismic resistance, high temperature .resistance, small size, low self discharge characteristics. Service life is twice that of conventional batteries. Market of maintenance-free battery also has two kinds: the first one in the purchase one-time electrolyte later use does not need to maintain (add additional .liquid); the other is the battery itself, the factory has been combined with good electrolyte and sealed, the user would not have been able to add additional liquid. <br> Battery for correct use and maintenance in the following seven points: <br .> 1. check the battery in the bracket with the bolt is tightened, the installation does not secure due to traffic vibration caused by damage to the shell. Also do not use metal on the battery in case of short circuit. <br> 2. .always view the pole and wiring is header connection is reliable. To prevent oxidation can smear Vaseline terminal protection agent. 3, unavailable direct spark (short-circuit test) method to check the battery power that would cause damage to the battery. <br> .4, notice of ordinary batteries to regularly add distilled water. Dry charged battery in use before the appropriate charge. As for the extra water maintenance-free battery is not an appropriate view cannot maintain the necessary supplementary distilled water helps to prolong service life. < .br> 5. battery cover should be smooth on blowhole. Battery charging will produce large amounts of bubbles to vent is blocked so that gas can't escape when the pressure increases to a certain extent it will cause battery exploding shells. <br> 6 ., battery pole and covered around there are yellow-white paste, because the acid corrosion a root column, line cards, retention, etc. These substances have very large, to promptly clear. <br> 7, when you need to use two batteries .in series with the best battery capacity. Otherwise affect battery life. <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br>.
