NLBA Reset Option is new and it is growing. Can you come with more details, for which chips ?

Since you have already been using Be2Works than you should know that changing DC is not a very good idea. Especially on Lenovo and Dell batteries.

DesignCapacity it is not mandatory to change it, the battery will function the same, even the cells are replaced by a higher capacity cells.

The only thing that is affected is the computation of Wear Level, just a value reported by most PC softwares as FCC divided by DC.

Yes and this is what i wanted to explain. Changing the DC on some chips will result in the battery fail to pass the bios check and the laptop will refuse to charge it. I guess the only reason why he wants to change DC is if he replaces the original cells with lower capacity ones so that PC softwares will show less battery wear.

I hope @p.porzi will return and explain in which condition he needed mandatory and be2works helped him.

If you want to ask put question mark at the end of sentence. Otherwise your post looks like statement instead.

Yes, some BIOS performs check of battery static parameters including Design Capacity. And could refuse to charge the battery if it's different then projected by maker. But not all, far not all notebooks doing it.

So in many cases you have a freedom to edit it to get correct SoH and ASoC calculation.

In many cases changing FCC is enough to get benefits of larger capacity cells, because ACPI driver and Windows uses RSoC% parameter for displaying charge percentage and to control laptop power.

And RSoC is always calculated based on FCC (Last Learned Capacity).

But sometimes editing Design Capacity is the only measure to get benefits of larger cells.

Just recent example.

Customer sent me Dell N71FM 65Wh battery. It's 3S2P 6-cells battery in 9-cells casing. So there is free not used space inside. He wanted to recell it with 9 cells to get 3S3P configuration and longer laptop working time.

During recelling FCC was changed from 6000 to 9000mAh as normally done when upgrading the cells. Design Capacity was not touched having in view it was Dell battery.

What was surprise that after one calibration cycle FCC was dropped to 6000mAh, so chip not allow to rise FCC more then Design Capacity, it was bq8050-D1 there. After discussion with customer we decided to change DC as well to 9000mAh and to check then if laptop Bios will be liked with it.

Later on when customer received the battery he reported all is running fine and he got about 30% addition in working time relatively to new one.
