This brand new AlienWare 14 A14 M14 M14X R3 R4 replacement battery. This battery is not the correct battery for the M14x R1 or R2 models (revision 1 or 2). You can find the the correct listing here: ( Alienware M14x R2 Battery). This is an internal or integrated battery and you will need to unscrew the back case in order to install the new battery. A small phillips head screwdriver is all you will need to open up the case. Li-ion battery technology provides longer run times with less weight. In addition, Li-ion batteries are not subject to the memory effect common with older battery technology. This laptop battery replacement is 100% compatible with the original battery specifications and is individually tested and backed by a 1 year warranty.
You can expect about 3 – 5 hours of run time with this computer battery when new, depending on your energy use.
Like all Li-ion primary batteries, your run time will decline over time.
This battery replaces the AlienWare M14 M14X R3 R4 series laptop batteries.
