Can I equip 61Wh battery on Framework Laptop 13 with AMD Ryzen 5 7640U? How much it does go long time after fully charged? Is there any issue about battery swelling when charging the laptop is continued after fully charged?

Welcome to the forum.
All Ryzen 5 systems include the 55Wh battery. Only Ryzen 7 systems include the 61Wh battery.
No laptop, phone, tablet, or other proper li-ion device will continue charging after it reaches 100%. To safely charge, li-ion chemistry requires an intelligent charge controller that stops at 100%.
If you wish, Framework Laptops have an option in the BIOS to limit charge / stop at a lower percentage than 100, but this is really just to prolong battery life in situations where the laptop is plugged in the majority of the time. Since li-ion batteries age faster when kept full 24/7.
Thanks.
So if I buy the Ryzen 5 laptop and replace the battery from 55Wh to 61Wh, is it possible?
Have all Framework laptops such intelligent charge controller?
I bewared that after change my laptop to Framework some battery swelling issue could happen to me.
Yes, you can do that.
Yes.
Some limited amount of swelling appears to be normal / not harmful for li-ions over the course of their life. But some companies pack their devices so tightly that they provide zero room for it, and so the device will bulge, just poor design honestly. I read that Framework Laptops are designed with room.

Thanks. So could I regard that there is no problem about battery swelling even though my laptop is plugged in almost all time? How about the battery duration of 55/61Wh?
From this : Framework 13 AMD 7040U review about 10h.
@Cleber Thanks.
As an engineer who previously worked with li-ion batteries on power tools. I would recommend using metal plates to physically prevent the battery cells from swelling. The reason why cylinder cells often have longer life compared to pouch or “lithium polymer” cells is that cylinder cells can’t swell or deform. Swelling on pouch cells causes delamination, which means the electrodes and the separator between them no longer fully in contact. This leads to less contact area and incomplete electrochemistry reaction result in higher internal resistance and lower capacity in addition to normal battery degradation so it’s not entirely not harmful. During testing, we was able to demonstrate that when plates are clamped on a swollen cell to its original shape, said cell has higher voltage and lower internal resistance during discharging.

Hi, So your telling us that the same case will not accept the 61wh battery? It’s my understanding all 13" laptops have the same case. is this true or not? It’s my understanding that you will only get 2% battery improvement by going to the bigger battery.
Hi, I’ve just ordered a new battery as I noticed the dreaded “case-bulge” on my Laptop 13, and the battery has “popcorned”. Natually, it’s out of warranty by a few months :o( Them’s the breaks… Anywho, I noticed a lot of threads about this happening, is this something intrinsic to the battery supplier Framework use? I’ve had a lot of laptops over the years, some of which I’ve replaced the batteries on because they were no longer holding change, but this I’ve never had one bulge up like this, so wondered if there are other supliers for this type of battery?
