How to buy a UNIWILL laptop battery?

• Part number of UNIWILL laptop battery, make and model of UNIWILL laptop

  Know your laptop name and model. We are sure you know the name of your laptop, eg. UNIWILL N258,UNIWILL N258AS,UNIWILL N258AX,UNIWILL N258KA,UNIWILL N258KAO.The model is a multi-component word that includes the line and actually model number.

  Essential to the purchase of your new laptop battery is the part number. A part number,eg. UNIWILL 23-UD7010-0F,UNIWILL 23-UD7110-1B,UNIWILL 258-3S4400-S2M1,UNIWILL 258-3S4400-S1S1,UNIWILL 258-4S4400-S1P1,is a unique identifier that is assigned to a part to simplify referencing and to unambiguously define a part within a single manufacturer. The part number above all is what needs to be known before going to buy your battery.

• Capacity of UNIWILL laptop battery

  Most laptop battery makers advertise their batteries power capacity in terms of 4400, 5200, 5600 or 5800 mAh. The basic idea is that 5800 mAh battery pack will allow your laptop to run longer than a battery with a 4400 mAh rating.The higher the capacity the more money you will spend, so if you need the longer runtime’s or you use applications that require more battery juice then buy the higher capacity.

• Voltage of UNIWILL laptop battery

  Voltage measures the volume of electricity that is delivered to your laptop. Most laptop chargers are rated at 19 volts. The extra voltage a charger has over a battery is so the charger can simultaneously power the laptop and charge the battery (if they had the same voltage rating the charger would only have enough power to run the laptop).

  For laptop batteries the most common voltage measurements are: 7.2V, 9.6V, 10.8V, 11.1V, and 14.4V. Since you cannot choose the voltage measurement for your laptop go with whatever measurement is closest to your original battery. Remember nominal voltage allows for slight deviation from the original but you cannot use a 7.2V battery if it requires 14.4V. The best example would be a 10.8V battery could be used with an 11.1V battery.

• Watt hours of UNIWILL laptop battery

  If the capacity of a Battery is defined in terms of Watt Hour, you will need to know the voltage of the battery and the current drawn to be able to calculate the life of a battery. Watt itself is defined as Ampere X Voltage. So if a 5 Volt battery has 20 Watt Hour rating, and, it draws 2 Amp current, then the Watt delivered by Battery = 10 Watts ( 5 Volts x 2 Ampere). The battery will last 2 hours. The calculator will calculate the battery life if the Watt Hour and the battery voltage is known. Here is the formula :Battery Life = Watt Hours / ( Voltage x Current in Ampere).

• Number of of UNIWILL laptop battery Cells

  The number of cells is important since the more cells contained in the battery the higher the capacity will be. To determine the number of cells in your laptop battery you need to have some general idea of what cells are being used in your battery. The most common battery cell is the 18650 and is manufactured by LG, Sony, Sanyo, Samsung, Panasonic and many others. The 18650 is a 3.6V cylindrical Li-Ion cell. 18650 has no memory effect (distinguish between digital memory effect) and longer storage life than NiMH battery cells. 18650 is light weight and has a high energy density. It is in effect perfect for building batteries for laptop and other portable power device.

• Retailer, Price and Warranty

  When choosing a retailer to buy a laptop battery from take into consideration the retailer’s reputation, the price, the warranty, and the return policy.The web site Warranty Policy:
