This brand new Lenovo X300 and X301 replacement laptop battery. This is the larger 6 cell battery which lasts as long as 5.5 hours with minimum power settings set on your laptop. This is much longer than the 3.4 hours the original 3 cell battery. This battery is slightly thicker than the original 3 cell battery (43R1965). The original 3 cell battery has been discontinued, so this is the only battery available as a brand new battery. 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 2 Year warranty.
You can expect up to 4-5 hours of run time with this computer battery when new, depending on your energy use. It is possible to get much longer run time with this battery, however this requires setting your screen at a much dimmer setting and disabling wireless and other functions on your laptop that consume power.
Like all Li-ion primary batteries, your run time will decline over time.
This battery replaces the Lenovo ThinkPad X300 X301 series laptop batteries.
