Newest ACER Aspire 4253 4743G 4750 4750G battery review -laptopbattery test
Aside from the merely adequate processor, the ACER Aspire 4253 has a healthy set of hardware, including Radeon HD 6310 graphics (integrated into the Fusion CPU), 3GB of memory, a 5400-rpm 500GB hard drive, the aforementioned 15.6-inch 1366-by-768-pixel display, and an 8X DVD burner. Connectivity is about average, covering 802.11 b/g/n wireless, gigabit ethernet, and both VGA and HDMI video output. The laptop also has three USB ports, microphone and headphone jacks, and an SD/MultiMediaCard slot.

The 4743G's performance is adequate, but not as snappy-feeling as that of a Core-based laptop--so don't expect that kind of speed. Its gaming frame rates were in the teens even at low-resolution, low-detail settings. In contrast, however, its 1080 video playback was as smooth as silk (with so-so audio through the speakers), so movies are more than just doable--they're enjoyable. Battery life for the 4743G is 4.5 hours, which is sufficient for most users but still 2 hours shy of what we normally see. It's not a particularly svelte traveler at about 6 pounds with the AC adapter, but few all-purpose laptops are.

At TECHNOESHOP we provide different types of batteries with different brands and volume discounts, import, export. Over 750,000 SKU’s original and compatible ACER Aspire 4750 battery is available.
However, it is a phenomenal choice for travel. It can also serve as a fine extra machine to keep around for guests. It handles web browsing and Email easily. It can handle heavy duty graphic and developer applications (such as Photoshop, Illustrator, Corel, Visual Studio and Eclipse) adequately – you wouldn’t want to work on the machine all day, but it will work in a pinch. It is inexpensive enough so that if it were lost or stolen, it wouldn’t be a disaster (just remember to avoid using it to store personal information). With 7+ hours of real-world battery life, you’ll get used to not carrying the power adapter with you everywhere you go or seeking out a power outlet every time you want to use it.
Lithium Metal Polymer
Developed specifically for automotive applications employing 3M polymer technology and independently in Europe with technology from the Fraunhofer Institute, they have been trialled successfully in PNGV project demonstrators in the USA. They use metallic Lithium anodes rather than the more common Lithium Carbon based anodes and metal oxide (Cobalt) cathodes.
Stricter regulations on shipping methods than for other cell chemistries.
Degrades at high temperatures.
Capacity loss or thermal runaway when overcharged.
Degradation when discharged below 2 Volts.
Venting and possible thermal runaway when crushed.
Need for protective circuitry.
ACER Aspire 4750G battery Knowledge
Lithium Manganese provides a higher cell voltage than Cobalt based chemistries at 3.8 to 4 Volts but the energy density is about 20% less. It also provides additional benefits to Lithium-ion chemistry, including lower cost and higher temperature performance. This chemistry is more stable than Lithium Cobalt technology and thus inherently safer but the trade off is lower potential energy densities. Lithium Manganese cells are also widely available but they are not yet as common as Lithium Cobalt cells.
