Laptop Battery FAQ – Before Buying a New Battery
I have seen different battery cell types like 6, 9, and even 12 cells, what are they?
This number indicates the number of individual cells used to make up the laptop battery. The more cells, the higher the capacity of the battery. Generally, the battery with the lowest number of cells is the standard battery that came with your laptop. The 9-cell or 12-cell batteries are the extended, higher capacity batteries that will provide you much longer run-time on a single charge.
Before purchasing a battery with more cells, you need to weigh up the benefits vs the extra size and weight, especially if you carry your laptop around with you all day.
Is the grade of the battery cells important?
In general, a laptop battery will provide between 400-800 life cycles depending on usage and battery quality. Lower quality or poorly manufactured batteries will provide fewer cycles, and a shorter overall lifespan.
- Highest Quality Batteries (Grade A Cells) – 12-18 months
- Medium Quality Batteries (Grade B Cells) – 10-15 months
- Low Quality Batteries (Grade C Cells) – 5-10 months
How long will the new battery power my laptop?
Actual battery run-time depends upon the power demands made by the equipment such as the applications you are running and your laptop settings. Our replacement batteries will last the same or longer than the original battery which came with the laptop when it was brand new (at the same capacity). Generally, a standard 4400 mAh will last between 45-90 minutes. You can calculate how long a higher capacity battery will last based on the mAh difference. A 7200 mAh battery will give you 64% more run-time, and a 10400 mAh will give you 136% more run-time than the 4400 mAh on a single charge.
How long does a laptop battery last? When should I consider replacing mine?
All rechargeable batteries wear out with time and usage. As time and cumulative use increase, the performance will degrade. For the typical user, noticeable reduction in run time generally will be observed after 18 to 24 months. For a power user, reduction in run time generally may be experienced prior to 18 months. We recommend buying a new laptop battery when the run time does not meet your needs.
