Motorcycle battery is generally divided into dry battery (maintenance free batteries) and water (water, battery battery) and what is the difference between these two kinds of batteries?

Maintenance free battery: maintenance free battery because of its advantage in structure and consumption of the electrolyte is very small, the service life of the basic does not need to add distilled water.   It also has the characteristics of high temperature resistance, shock resistance, small volume, small self discharge.   Life is generally two times the ordinary battery.   Maintenance free batteries on the market there are two types: the first one at the time of purchase one-time add electrolyte for use in the future without the need for maintenance (add liquid); the other is a battery factory has been added a good electrolyte and sealed, the user can add liquid.

Water is generally composed of lead-acid battery positive and negative electrode plates, plate, shell, electrolyte and wiring pile head, the discharge chemical reaction is dependent on the positive plate active material (two lead oxide and lead) and negative plate active material (sponge pure lead) in the electrolyte (sulfuric acid) are under the action of the gate frame the plates, with lead antimony alloy manufacturing traditional battery, maintenance free battery is made of lead calcium alloy, the former for the latter with antimony, calcium, this is the fundamental difference between the two.   Different materials will have different phenomenon: the traditional battery will reduce the phenomenon of liquid in the process of using, this is because the gate frame of antimony can sponge pure lead pollution on the negative plate, weakening the back EMF in the storage battery is fully charged, resulting in excessive decomposition of water, large amount of oxygen and hydrogen. From the positive and negative plate to reduce the escape of electrolyte.   Using calcium instead of antimony, can change the battery fully charged after the counter electromotive force, reduce the charging current, liquid gasification rate decreased, thereby reducing the loss of electrolyte.

The maintenance free battery lead calcium alloy grid by charging water produced by the decomposition of less moisture evaporation is low, add the shell sealed structure, release the sulfuric acid gas rarely, so it is compared with the traditional battery, do not need to add any liquid on the pile head connection, wire less corrosion resistance. Overcharge ability, large starting current, power has the advantages of long storage time etc..

Maintenance free battery for its normal charging voltage, electrolyte produces only a small amount of gas, the plate has a strong anti overcharge ability, but also has small resistance, good cold starting performance and long service life than conventional batteries, and so the whole during use without adding distilled water in normal charging system next, without additional charge removed from.   But the proportion of the electrolyte in the maintenance inspection.

The water level at least once a battery to use in a year's time, to see if the water loss, if less than the minimum liquid machine scale, timely replenishment, maintenance free battery if it is often excessive dehydration phenomenon belongs to the charge discharge process, can also be appropriate to use water, other conditions are not water maintenance, general factory brand battery life longer, battery water in more than 3 years, maintenance free battery in 4-5 years, but there is some brand-name batteries due to the use of the recovery of lead or no purification of lead, the service life of large discount, generally in a year or so will fail, but also in the design of anti existence defects. The explosion so it is best not to buy cheap inferior batteries!

Proper use and maintenance of batteries are mainly the following 7 points:

1, check the battery fixing bolt on the bracket is tightened, installation is not reliable due to traffic vibrations caused by shell damage.   Also do not put metal placed in the battery to prevent short circuits.

2, often see the pole and the terminal connection is reliable.   In order to prevent post oxidation can smear Vaseline protecting agent.

3, can not direct ignition (short circuit test) method to check the battery that will cause damage to the battery.

4, ordinary lead-acid batteries should pay attention to regularly add distilled water.   Dry charged battery before using the best appropriate charging.   As for the maintenance free battery is not water cannot maintain appropriate view when necessary to add distilled water helps to prolong the service life.

5, the battery cover hole should be smooth.   The battery will produce a large number of bubbles if the vent is blocked so that gas cannot escape when the pressure increases to a certain extent will cause the battery shell burst when charging.

6, paste in the battery pole and cover around often have white, this is because the sulfuric acid corrosion column and line cards, fixation by.   These substances have high resistance, should be promptly removed.

7, when used in series battery capacity is equal to the best with two batteries.   Otherwise it will affect the service life of the battery.
