If you're an Apple MacBook Pro user, you'll know the importance of keeping your system properly maintained, and of optimizing its performance with memory upgrades and updated software. You probably don't think too much about your Apple laptop battery, but if it runs out of power on a long flight or suddenly won't hold a charge before an important client visit, it could mean lost productivity and in some cases, even lost data. At USB Phone World, we carry Apple A1321B replacement batteries for Apple MacBook 15-inch computers. Our replacement computer batteries are manufactured in accordance with OEM specifications and are designed to fit and work exactly like the factory shipped originals. The Apple A1321B battery is 11.10V with a capacity of 5600mAh, and the average running time after being recharged is 3-5 hours. This can vary depending on the operating system, brightness of the screen and if you are using wireless devices. CD and DVD burning and 3D computer games are also "energy hogs" and will quickly drain a battery's power. It is advised that you keep this in mind when you're away from an electrical outlet for an extended period of time.
Our Apple laptop battery replacements are good to have on hand if you're frequently on the road for business, or if you regularly use power-draining programs while on battery power. Consider having a spare in case of emergency. This is especially important if you have an older system, as a battery over time will begin to lose its capacity to hold a charge. In addition to Apple A1321B batteries, we also carry laptop replacement batteries for other Apple models.
