The ability of this Li-ion laptop battery dell 0KY266 for latitude E6400 to run away with electricity is several times stronger than that of many other types of batteries. For example, while other batteries have at most only eight hours of service time, which is indicative of their inferior quality, this battery has at least eight hours of service time, which is exhibitive of its superior quality and unparalleled performance. Furthermore, a charge of this battery by the adapter of the laptop computer makes demands on electric supply which the laptop is using, so every laptop, in a real sense, has no compatible adapter, and users are not recommended to buy it, because electric currents, voltages, power ports vary from laptop to laptop.
Although the current market has some cheap compatible adapters, they will show a lot of problems in their actual usage. For example, despite the identicalness of the ports of adapters with each other, the electric voltage and current below the standard values of the machine can lead the laptop that is working to the fullest extent, to be unable to obtain ample charging electricity, which is harmful to the Li-ion laptop battery dell 0KY266 for latitude E6400. And given the electric voltage and current are below the machine′s standard values too much, then the laptop cannot be opened or charged. That is why it is proposed that users buy this battery suitable for the automatic adjustment of the situations of the electric adapter to a reasonable supply of the laptop computer with electricity. And the best way to keep the battery without causing the loss of its cells is to make its discharge at 40% for storage, keep it off damp and high temperature, and put it in a cool and dry place whose temperature must not be so low as to greatly reduce its capacity. The ideal temperature is 20 degree centigrade.
