How to choose the right laptop battery
Remember that old adage “no two snowflakes are alike”? Well there’s a modernized version of the age-old saying and it goes a little something like this: “No two laptop users are alike.”
Each and every person that uses a laptop has their own unique way of doing so. Because of this, a notebook battery that works well for one person may not necessarily be the right solution for someone else. For example- the same way that an aggressive driver will take a heavier toll on a vehicle and reduce its efficiency, an aggressive laptop user will put more pressure on a battery and therefore require a battery more suited for his style of use.
When choosing a battery, the main quality that you need to consider is the amount of energy that can be stored in a battery. This is measured in Watt- Hours (Wh). For longer runtime per charge, choose a battery with a greater Wh rating.
Before someone is able to accurately decide what type of battery is best suited for their portable power needs, they need to know the differences between each battery and what it is that each brings to the table. For instance, putting additional cells in battery packs turns a standard battery into an extended battery. While extended batteries are a bit heavier and cost more than just a standard laptop battery, they allow laptop users a significantly increased amount of time of laptop use in between charges.
Cell capacity is another factor to consider when setting out to but the correct battery. Some of our laptop batteries are made with 2.2Ah cells versus 2.6Ah cells, and this will affect the ever so precious Wh rating that was mentioned earlier in the post. Here’s why:
Acer aspire 3690 battery | 2.2Ah cells with 6 cell will have 4400mAh = 49Whr |
Acer aspire 5920 battery | 2.2Ah cells with 9 cell will have 6600mAh = 73Whr |
Dell inspiron 1520 battery | 2.2Ah cells with 9 cell will have 6600mAh = 73Whr |
Dell latitude d531 battery | 2.6Ah cells with 9 cell will have 7800mAh = 87Whr |

If you want longer runtime you should choose higher capacity laptop batteries, but these batteries are higher cost and heavier on weight. If you want lighter weight and lower cost you should choose lower capacity but these batteries have lower runtime.
As we mentioned earlier, extended battery packs (HP DV6500 Battery, Toshiba PA3399U-2BAS Battery ) are available option as well. These are ideal for those who really want to extend their run time and don’t mind the heavier weight.
Simple enough, right? Just remember- “No two laptop users are truly alike”. Next time you set out to purchase a laptop battery, be sure to arm yourself with the knowledge that will allow you to choose the correct one for you.
Note: When used under the same conditions, a lower capacity battery will wear out faster than a higher capacity battery because it has to be charged more often.
