Firstly, the form of damaging the battery
Arising from the use of battery failures, mainly due to maintenance and use resulting from the inappropriate. External battery failure, there are shells and crack sealing lid glue dry, loose clusters and corrosion, etc. internal fault with hob, self-discharge within the short-circuit the active excretion of pigs plate, etc..
During use, mainly to prevent excessive discharge and overcharging. Excessive discharge plate cooking, even the council of the active substance can not participate in the formation of a chemical reaction PbSO4 white crystals, which is one reason for early damage batteries, and the same time, dell kd476 battery following excess discharge at high current, such as excessive use of choke, when large current discharge is too long, but can not be replenished in a timely charge, causing song arcade plate, partition damage, so the battery in poor condition. Excess energy pricing of water electrolysis to produce hydrogen and oxygen, so the pore plates produce a pressure plate off and save some of the active ingredient.
Secondly, the factors that affect the battery capacity
Factors that influence the capacity of the battery are: tectonic plates, the size of the discharge current, temperature of the electrolyte and the electrolyte density, whose charge and discharge current and temperature, greatest impact. Such as charge and discharge current is too large, will make a significant change even in the business of the board surface, a much smaller capacity, while lower temperatures lead to electrolyte low mobility, contraction plaque, slow chemical changes, hp f4809a battery increased battery internal resistance. If the temperature decreased to 30 ℃ 1 ℃, capacity will increase to about 1%, its resistance also increased. Therefore, in cold regions, temperature from -20 ℃ below capacity fell to 60% increase resistance, the engine often do not start, often feel less battery power. Easy cold area of the excessive discharge, while the temperate regions are often over-charging problem. Therefore, a good battery to use must be based on local climatic conditions for the real situation, to master the law of its use. The rechargeable battery must be based on the selection of different situations with appropriate methods and proper use of the charging device, so as to strengthen the capacity of batteries and prolong battery life.
3, battery charging method commonly used in
Pricing methods are commonly used: the rate constant load, constant pressure and pulse fast charging, the battery in the use of scarcity pricing often take on a regular basis to supplement charging. To maintain a certain capacity and prolong battery life, been required to charge and recharge cycles of the year. To remove the plate from drying failure, requiring pricing to vulcanization. The first phase of early perception of the load current at its rated capacity of 1 / 15, the second phase of load current by half. Additional charge for the first phase of the nominal load current capacity of 1 / 10, the second phase was reduced by half, the characteristics of lead acid battery is fully charged: maximum terminal voltage of 2.7 V or more, and no longer in the 2h-3h increased; compaq presario r3000 battery battery produces a large number of air bubbles in the electrolyte boiling.
Fourthly, use and maintenance of batteries
The proper use and maintenance of batteries include:
1, an analysis of the machine electricity consumption will control the voltage generator terminal in the specified scope. For example, the mechanical work during the day often charge a long time, discharge time is short, to avoid an excessive burden of the issue should be properly reduce the load current, the mechanism of night work, to launch frequent avoid excessive discharge, must be adapted to try to load current ratings greater, in the parking should be sufficient electricity for the next transaction.
2, attention to work machines or vehicles, the temperature conditions. In colder regions, we must pay attention to the isolation cell, a reasonable choice in terms of density of the electrolyte, to keep it fully charged. Fill with distilled water when the load to prevent freezing. Must start before the engine is hot, and the proper use of each start-up time starter does not exceed 5S, again, begin to be 15S interval, two consecutive first term, should be and then start troubleshooting.
3, to improve maintenance of the battery. sony vgp-bps2 battery If the only use, no maintenance, coupled with the poor conditions on the role of the battery (vibration, dust, pollution), the consequences are obvious.
Battery maintenance include:
①, the external battery to keep it clean, always remove the battery cover of dust and dirt overflow of the electrolyte to help prevent self-discharge.
②, periodically check the lid holes, so that it remains free of debris and if the holes were blocked, battery resulting gas burst.
③, solid installation requirements of the battery, mechanical bumps in the road driving accident, the battery can not install the seat up and down on the impact the fight against the rubber mat battery-vibration pads at the bottom should be order to avoid upset, loose wiring and internal polar head plate damage. In addition to verifying the installation of a solid, but also notes that removing the battery clamps produced sulfate oxide. toshiba pa3399u-1brs battery Vaseline can be used after cleaning rust Guajing materials to avoid corrosion longer. Should always check the connectors son, to ensure reliable contact.
④, regular checks of the level of liquid electrolyte. Electrolyte in the battery charge time in May is as natural evaporation is reduced, the plate surface exposed, the exposed part of it will soon heal, so that smaller battery capacity, even after adding the electrolyte to the dive vulcanized part of the plate is also difficult to restore the status quo ante. Therefore, timely check the liquid level of the battery and the timely filling in distilled water or electrolyte. Usually inspected once a week in summer, winter, two weeks to check again. Translucent plastic shell with batteries, you can see the internal height liquid outer shell, shell, there are still down two standard lines, the height of liquid as it can between two lines marked. With black plastic for the tank battery, check fluid when draining the cover of Canada with your eyes observe and evaluate the surface height can also be used a small tube inserted the battery, hold the tube with your fingers missing you check the electrolyte. Under normal circumstances, the level of the liquid electrolyte should be above the plates 10-15mm. Found that the liquid level is too low add distilled water when completed, should the electrolyte is spilled or overflow, and should add to the electrolyte. It is noteworthy that can be tap water, river water, well water and ordinary water other than distilled water to add.
⑤, always check the specific gravity of the electrolyte. ibm thinkpad t40 battery More water is found, they should consider whether the excess charges, found the density is too low, it is necessary to examine whether the excessive discharge, it should be added the burden.
⑥, battery warm in winter to prevent frost cracks, this long battery life.
