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.
