4 Cell Vs 6 Cell Battery: What’re The Key Differences?

Key Points:

  • 6-cell will be perfect if you are going to heavy-use but if not then 4-cell will do just fine. Because, it’s fast charging and easy to carry.
  • 6-cell has a better reserve capacity. It will last long on one-time charge but the battery will make your device a bit heavier.

You might be thinking about which one will last longer between 4 Cell Vs 6 Cell Battery? And how long should the reserve capacity be? Are 4 or 6 cells enough for your device?

To be honest it totally depends on your purpose and what you will do using the battery. A 6-cell battery will provide you with more run-time. Where 4-cells batteries are lightweight and get charged fast.

I have made a detailed comparison along with a comparison chart for a quick look between these two batteries. Let’s scroll below and learn more

4-Cell Battery

The number of cells doesn’t define the power or the capacity of a battery. It does contribute and more cells mean more power but the main factor here is watt-hour.

The more the Whr is the better it will deliver you. 4-cell means that it has 4 cells in its battery pack along with 4 lithium-ion 18650 type cells.

The battery capacity always depends on the user’s purposes. 18650 can provide you 2AHr range to 3.4Ahr, so to be honest you should always look for the higher Whr and not the number of cells.


  • Lightweight
  • Gets charged fast
  • Can be carried easily


  • Less reserve capacity

6-Cell Battery

More cells mean more power – it’s true but not entirely true. If a 4-cell battery has more Whr capacity than a 6-cell battery then it doesn’t matter the cell amount. A 4-cell will be counted as the powerful one.

But obviously, a 6-cell battery will provide you with more run-time. If your purposes are for heavy usage then you might want to go for it.


  • More reserve capacity
  • More voltage
  • More capacity


  • Heavyweight
  • Takes more time to be charged

4 Cell Vs 6 Cell Battery: The Detailed Comparison

Here’s a quick comparison chart is given below for a quick glance:

Reserve capacity2-3hrs4-5hrs
Charging time1-2hrs2-4hrs
Weight276 g (0.61 lb)0.45 kg (1.0 lb)


As I have said before, more cells mean more power but the entire decision depends on the user’s work purposes. It’s always true that 6-cell will give you more facilities.

Such as more reserve capacity, more Watt hr but it becomes an easier decision if you be clear with how you are going to use it and on what purposes. So, the amount of cells doesn’t define the power of the battery in a frank discussion.


In this case, 6-cell comes with 4400mAh which is way more than a 4-cell battery (2600mAh). More mAh means more run-time.

If you need a battery for heavy use and long run-time then 6-cell should be the priority but other than 4-cell should do just fine.

Reserve capacity

Reserve capacity means how long the battery will back you up without getting recharged. 4-cell can offer you 2-3 hours and for 6-cell it’s 4-5 hours. 6-cell is way ahead of 4-cells here.

If you need the battery for heavy use then you must go for the 6-cell battery. And otherwise, 4-cell is enough for one-time use.

Charging time

Charging time is an issue if you are travelling or in hurry. 6-cell can give you a long time use experience which 4-5 hours but it will take a long to be recharged again. It’s good for your device’s and battery’s health if you full-charge it before using.

6-cell will take 2-4 hours to be fully charged whereas 4-cell will take only 1-2 hours max. So, if you have the time to full-charge the battery before using it, then you should go for the 6-cell since it will comfortably give you 4-5 long hours of use time.

If you don’t want any heavy work done by your device you can definitely move on with a 4-cell battery. Which will easy to be charged and be ready to be used again.


Weight is a priority because you might carry the device here and there. Better the battery, the bigger the size. So if you are going with a 6-cell battery (0.45kg) you have to keep in mind that it will be heavier than the 4-cell one (276g).

Freequently Asked questions (FAQs):

What does 4 cell batteries mean?

4-cell means that it has 4 cells in its battery pack along with 4 lithium-ion 18650 type cells.

What does WHR mean in a battery?

Watt Hour. Watt-hour basically means the amount of power used over an hour (1hour).

How long does a 6-cell battery last?

Charge times mainly depend on the battery quality and the reserve capacity. Normally a 6-cell battery can provide you 4-5 hours if fully charged.

How long does a 4-cell battery last?

A 4-cell will last 2-4 hours max after being full-charged. Though it depends on other matters such as reserve capacity.


According to all the facts I have stated above, the bottom line is your decision stands on your work purposes and obviously on the device’s capacity. If your device isn’t capable of operating a 6-cell battery then it’s literally a bad idea to purchase a 6-cell battery.

After that, if you use your device only to do the usual stuff like office work and all, then you don’t need 4-5 hours of run-time. It will also take approximately 3-5 hours to get full-charged again before using. Time management can be an issue here.

If you carry your device with you all the time, a 6-cell battery can be a bit of a hassle since it’s heavier than the 4-cell one. This is also a concern. I have explained it all but the final decision is yours to take.
