What battery should I choose for my Laptop if there are differences in Watt Hours (Whr) or Milliamp Hours (mAh)?

Sometimes laptop batteries from different manufacturers will have different Watt Hour (WHR) or Milliamp Hour (mAh) ratings. Also, some batteries are designed to have higher capacity. Also, a battery manufactured a year or two after the OEM battery may just be better due to slightly new technology or other factors. Generally speaking, a Higher Whr or mAh on the same system, using the same operating conditions will deliver longer laptop battery run time.

At ReplacementPower.com you can find both regular capacity and high capacity batteries. If you are happy with the life of your original notebook battery, a regular capacity battery is all you would need. But if you are looking for longer life, go for the high capacity laptop battery (the one with more mAh). In general they will provide 50% more working time (depending on application).

What is a Refurbished Battery?

Caution! A Refurbished Battery is simply a Used Battery. The extent to which it has been refurbished is always an open question.It may have been cleaned up or it may have some minor replacement of parts or even cell replacement. Refurbished Batteries typically sell for prices that are 25%-50% less than a New Battery. This reduced pricing reflects the reduced performance and value of these used batteries. Also, multi-cell batteries, like those used in high end applications such as notebook and laptop computers, are particularly susceptible to downgraded performance when they are refurbished. It is highly recommended to stay away from companies that sell refurbished batteries. Also stay away from companies that offer to refill your old batteries. In order to achieve maximum functionality and performance always buy new products.

If you are looking for a new laptop battery you should check out sites like MobileTechPower.com and ReplacementPower.com. Each site sells brand new 100% OEM compatible laptop batteries and laptop ac adapters. Every item is backed by a one year warranty so there is no reason not try their products.

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.

Why are Original Equipment Manufacturers (OEM) Laptop Batteries more costly than the Equivalent Parts in the After Market?

OEMs are focused on the next new product. They would prefer that you buy the next new laptop rather than extend the life of the product that you currently own. By making accessories, such as your laptop battery and laptop ac adapter, expensive, you are encouraged to upgrade the device rather than buy the replacement parts. Since they focus on the development of the next new item, the maintenance of replacement part inventories and the smaller production runs associated with manufacture of replacement parts is an added expense and a distraction from their core business.
