Why are there many different part numbers for my device?

The Original Equipment Manufacturers will make Batteries, AC Adapters and other Accessories with part numbers that change for a variety of reasons. They may issue different part numbers to indicate date of manufacture, the country or the factory where the part was made, or even just to indicate that particular production run. So, there could be laptop batteries or laptop ac adapters with 10-12 different part numbers that are identical in every other way and that are all compatible with you notebook.

Keeping extremely accurate and up-to-date cross references of this data is often a tricky task that most resellers (and some OEMs) have trouble doing. But not PowerCenter.com. This seems to be their area of expertise. When they offer a product that is for a specific model and series, or as a replacement for a specific part number, you can buy with confidence knowing that the item will work in your device and that it will equal or exceed the performance and specifications of the part it replaces.
