With the coming of winter, the temperature decreases, and the starting ability of our motorcycle battery is also undergoing a severe test, because the decrease of temperature will reduce the chemical reaction activity inside the battery, and the ability of chemical energy inside the battery to convert electric energy will be weakened. This directly leads to the difficulty of cold start of many cars, the extension of ignition time, and even the inability to start. So let`s talk about the battery today.
Motorcycle battery is generally divided into dry battery (maintenance free battery) and water battery, so what is the difference between the two kinds of battery?
Maintenance free battery introduction: due to its own structural advantages, electrolyte consumption is very small, in the service life of the basic need not add distilled water. It also has the characteristics of shock resistance, high temperature resistance, small volume and small self discharge. The service life is usually twice as long as that of ordinary batteries. There are also two kinds of maintenance free batteries on the market: the first is to add electrolyte at one time when purchasing, and then do not need maintenance in use (add supplementary solution); the other is that the battery itself has been added electrolyte and sealed when leaving the factory, so the user can not add supplementary solution at all.
The general water added lead-acid battery is composed of positive and negative plates, separators, shells, electrolytes and terminals. The chemical reaction of its discharge depends on the active substances of positive plate (lead dioxide and lead) and negative plate (spongy pure lead) is carried out under the action of electrolyte (dilute sulfuric acid solution). The grid frame of electrode plate is made of lead antimony alloy in traditional storage battery, and the maintenance free storage battery is made of lead calcium alloy. The former uses antimony, and the latter uses calcium. This is the fundamental difference between the two. Different materials will produce different phenomena: the traditional battery will reduce the liquid in the process of use, because the antimony on the grid will pollute the sponge like pure lead on the negative plate, weaken the back EMF in the battery after full charge, cause excessive decomposition of water, and a large amount of oxygen and hydrogen will escape from the positive and negative plates respectively, so as to reduce the electrolyte. At low temperature, the output power of this kind of battery is reduced due to the increase of electrolyte viscosity, permeability and resistance, which makes it difficult for the starter to drive the engine and may not reach the minimum starting speed, which affects the engine starting.Because the maintenance free battery uses lead calcium alloy grid frame, the amount of water generated during charging is less, the amount of water evaporation is low, and the shell is sealed, the released sulfuric acid gas is also less, so compared with the traditional battery, it has the advantages of no need to add any liquid, less corrosion of butt wire pile head and wire, strong resistance to overcharge, large starting current and long storage time And so on.
Under normal charging voltage, the electrolyte of maintenance free battery only produces a small amount of gas, the electrode plate has strong anti overcharge ability, and has the characteristics of small internal resistance, good low-temperature starting performance and long service life compared with conventional battery. Therefore, it is unnecessary to add distilled water during the whole service period, and it is not necessary to remove it for supplementary charging under normal charging conditions. However, the specific gravity of electrolyte should be checked during maintenance.
The water battery should check the liquid level at least once in a year to see if it loses water. If it is lower than the minimum liquid machine scale, it should make up water in time. The battery is maintenance free. If it is a water loss phenomenon caused by frequent overcharge and discharge, it can also be used with appropriate water. In other cases, it is not necessary to add water for maintenance. Generally, the service life of brand-name batteries in the factory is long, so it is necessary to add water and electricity The battery life is more than 3 years, and the maintenance free battery life is more than 4-5 years. However, due to the use of recycled lead or no purified lead, the service life of some miscellaneous batteries on the market is greatly reduced. Generally, it will be invalid in about one year, and there are also defects in the design of anti explosion. Therefore, it is better not to buy inferior batteries at a low price! Our company's Starlight motorcycle lead-acid batteries have a complete range, with a shelf life of one year. Our products are exported to 40 countries and regions! Our company has always been convinced that the principle of good faith for the customer first, warmly welcome new and old customers call the inquiry letter.
