E7270 3 cell vs 4 cell battery

Hi,

I'm considering getting the E7270 with 12.5" 1920x1080 non-touch screen, i5 6300U and 256GB SSD and wondered if anyone has any experience with recent 3 and 4 cell batteries?
What is the real life difference between them?

 

I've no experience with this notebook but the 3 cell battery is 37Whr and the 4 cell is 55 Whr so it has about 50% more capacity. Which, for a given usage pattern, means 50% more run time. Personally, for 105g (about 4 ounces) extra weight I wouldn't hesitate to get the bigger battery. It might be good for all day whereas the small battery wouldn't. If you are frugal you might get 5W power drain. 6W or 7W is more typical for reasonably light usage. And a Lithium battery which is regularly fully drained will tend to wear out faster.

I agree with John, I usually alway go for the larger battery unless the # of Whr is almost the same which it usually isn't. Sometimes with Dell, you also have more control over charging behavior with the larger batteries such as setting custom charging thresholds such as charging to 95% rather than 100% and letting it discharge to 60% before it charges. Those are the settings I use personally, mostly because it fits mu usage pattern and tends to keep the battery healthy longer.
