I plan to use 55Wh most of the time when working at home while laptop will be connected to docking station (charge level set to 80%).
Furthermore, I plan to insert 61Wh batter when I’ll need to travel and any 1Wh will count, with charge levels set to 100%. I travel for a week or two every 1–2 months. I’ll take a travel power adapter, but mostly will work on battery.
I would like to ask if there are any hols in my plans and what can go wrong.
Additionally, I’ll store battery not in use charged to 50-60%.
If you are concerned about battery life on longer trips just keep the 61WH battery installed. Like @Shawn_D_Alimonte said, you might wear out the connector/contacts, or worse bend a pin from swapping them. Yes they are meant to be replaced, they are not designed to be swapped like older laptops that had a battery you could snap in and out.
When you are at home and docked; limit the charging to 70%. Then when you are going to be travelling change it back to 100%. That will give you the most life out of it. The battery is specified to last a long time and over a lot of charge cycles. More so than the cheaper battery packs used elsewhere in the industry.
