Less than the long-term charge, no reaction of active substances leads to irreversible high-positive large particles PbS04 grain (ie, irreversible sulfate) to enable the battery capacity decline in resistance increase, charging more difficult, resulting in early damage to batteries. Therefore, as far as possible to ensure adequate battery power, to prevent irreversible sulfation. TOSHIBA Laptop Battery Laptop BatteryACER Laptop Battery 2, charging the choice of frequency Battery charge cycle life on the great influence on the depth of the basic exponential change. This is because the positive active material for Pb02, the combination of fastness is not high, discharge into PbS04, charging Shiyou into Pb02, andThe volume ratio of about 2:1. Therefore, positive plate, the active material expands and contracts will be repeated so that the connection between particles gradually fall off, so that loss of battery discharge characteristics of active materials as "anode mud" so that battery performance degradation until the end of life. The deeper depth of discharge,Dell Latitude C600 Battery, Dell Latitude C610 Battery, Dell Latitude C640 Battery, Dell 1691P Battery, expansion contraction the greater the damage to the active material binding the larger the shorter life expectancy; and vice versa the longer cycle life.IBM thinkpad t41p battery IBM THINKPAD T42 Battery Charging process is the reverse electrochemical reaction discharge reaction process, if the rechargeable electrochemical reaction process carried out in an ideal state, this process should be mutually reverse reaction, that is filled into the electricity and the release of electricity should be almost equal. However, in a serious analysis of gas state, the effective charging energy consumed in the electrochemical reaction process not reach 40% of the total electricity consumption, that is a waste of electricity over 60%. Gases within the porous electrode gathered in the batteries, reducing the electrolyte and porous electrode contact area, that is, charging the electrochemical reaction interface is drastically reduced, so that chemical reaction speed reduced charge, the charge is very difficult to extend the charging time.Gassing serious damage batteries: IBM ThinkPad R60 Battery IBM ThinkPad T60 Battery ? a large number of gases to the electrode active materials are scouring effect, so that active substances that can loose and shedding. ACER Laptop Battery DELL Laptop Battery HP Laptop Battery ? In the high polarization voltage, the positive plate grid will produce severe corrosion, generate Pb02, the corrosion and electrochemical survival Pb02 is completely different, which is not reversible oxide, conductive poor, enable grid deformation, embrittlement, loss of the role of skeleton and conductivity.Dell Latitude C610 Battery, Therefore, in the charge should be possible to prevent the overcharge.
