This brand new eMachine e730 replacement laptop battery is especially designed for your eMachine laptop. We have built this battery cartridge with the very best component parts available to keep up with the increased power demands of your eMachines laptop. Consequently, this battery contains the longest running and the very best quality Lithium-ion rechargeable battery cells available from our South Korean supplier. There are cheaper batteries in the marketplace using cheaper li-ion cells that do not run as long on a single charge and neither do they have as long a service life as these top of the line computer batteries. This is the most expensive component inside your battery. Cheaper batteries use inferior cells that sometimes last only 6 months before wearing out completely. In addition, cheaper batteries have a much shorter run time than our more robust 5200 mAh lithium-ion cells. Cheaper batteries use the lower capacity battery cells which are identified as 4400 mAh capacity. This battery ships from our Ohio warehouse with free ground shipping anywhere in in the continental US. Expedited and international shipping is also available. These costs will be displayed once you enter your address in the checkout phase. This eMachines computer battery replacement is 100% compatible with the original battery specifications and is individually tested and backed by a 2 Year warranty. We feel so confident about the quality of our batteries and power adapters that we offer a unconditional 30 day money back guarantee on all purchases. Further, if one of our eMachines batteries fails to perform upon arrival, we will ship a brand new battery to you as well as pay all shipping costs to replace and return it..

You can expect about 2 hours to 2-1/2 hours of run time with this e730 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 eMachine e529 series laptop batteries.
