Rechargeable batteries can be considered as micro-batteries. its basic principles is same with the car battery , that is, positive and negative electrodes are composed of a metal material , chemical energy storage media is added in it. before leaving the factory,Rechargeable Ibm thinkpad t40 battery is activated ,charged and discharge in the production line.
Rechargeable batteries are different from the ordinar disposable alkaline batteries. with normal battery discharge, the voltage linear decrease, and can not be restored. The voltagere of chargeable batteries reduced with a reduction in electricity while in use (loading) , but the cessation of use (off load),whether remaining amount of power regardless is little or not ,the voltage will be restored to 1.2V or slightly below. because charge voltage is higher than the Dell inspiron 6000 battery voltage in charging, after charging , the battery voltage go up to 1.4V or so general, but shelved for a while, charging the battery will return to 1.2V.
Any battery, including batteries and rechargeable batteries, can not over-discharge. Otherwise, light in reducing battery life, in serious cases will cause the batteries short-circuit, the Ibm thinkpad t400 battery is completely broken. Its appearance is the battery voltage drops below 1V, and may only have a few 0:00 V, a charge immediately washed over very quickly, but then a load right away have no electricity.
It should be clarified, but also very important. If the rechargeable batteries are not used for a long-term, should discharge the battery, rather than washed over. When fully charged, rechargeable batteries, such as a long-term need, due to chemical reactions within the battery will shorten the battery life, and even damage to rechargeable batteries. This is not the same as with the Ibm thinkpad t61 battery . The new rechargeable battery are fully discharged in the factory . There is no electricity in rechargeable batteries and voltage can not be saw . Rechargeable battery with or without electricity, voltage is 1.2V. Through the following ways to verify: the new rechargeable batteries (not completely red electricity) into DC, will find no power of a few can not shoot.
Now on the market of automatic red appliances, a lot of batterycan not be charged. Charger are included with the instructions given in a variety of capacity rechargeable Dell inspiron 6400 battery charging time, but often not to the nominal time to recharge to end. Full power is not red rechargeable battery for DC, if DC is the result of electrical charges. You often see complaining about color, the same machine, other people’s power, its own special charges electricity. Is likely to be full of rechargeable batteries, not red. From this point may wish to look for reasons. Some automatic charger with a charging function of turbulence. In this charger, the rechargeable battery in the red after full power continue to use the turbulence in the red for one hour. This rechargeable 17inch apple macbook pro akku can better washed over.
In addition, the new rechargeable batteries should be full charged and discharged for 3 – 5 times ,it can achieve the best condition. The use of rechargeable batteries should cultivate good habits, compulsory full no power (DC auto-shutdown), the further charge. Whether or not automatic charger, red finished immediately after power-rechargeable Dell inspiron 710m battery should be removed
