They say...it's no good to always leave

your battery in the laptop when it's plugged and the battery always stay full at 100%. So, since I rarely need the battery, I was removing it and put it back in like every month or so. Now, I just bought a new laptop and...you can't remove the battery unless you dismantle the laptop Acer Aspire 3 A315-21-4808

 

Correct. The way things are progressing, batteries are no longer hard structures encased in plastic that snap in and out. Currently, batteries are being made in odd shapes to fit in odd spaces within the laptops. They now have a more fragile structure to make them more flexible, in a sense. Due to this, they are more hazardous to handle and manufacturers have started to integrate them into the design rather than make them accessible for removal.

The up-side is battery tech has also greatly improved in the last few years. More charge cycles, less degradation, more idle/shelf life, and greater life span. In essence, you no longer need to remove the batteries to protect them from over-cycling or heat degradation. Batteries today are more robust than even 3-5 years ago.

 

The cynic in me says that the driving force behind this is less of safety concerns and more of planned obsolescence.

 

I agree with planned obsolesce . But in smartphones at least we also get water resistance and don't forget about the fact that we also get slimmer devices because of this.

 

Removing all that plastic around a battery, and all the space lost by having the battery socketed also means that the OEM can fit a bigger battery, also, almost all removable batteries are based around 18650 cells, now with the thin and light craze there is not enough thickness in the chassis to use 18650, so everybody uses pouch cells that are rectangular, and have more freedom in placement.

Also, you can limit battery charge level to around 70% if you dont use your battery all that much, LiPo prefers to be around 50-70% charge level for storage.

 

I had some battery horrors with one of my gaming laptops where the battery having some sort of voltage issue I suppose, and the power brick would stop working after awhile because it wasn't playing nice with the faulty battery. So my battery was actively killing my power bricks. There was no indication that the battery was faulty though and so I just assumed the power bricks were just bad. I went through three separate power bricks before eventually isolated it to be my battery and then I never had that issue again afterwards. Ever since then, I'm a bit skittish with batteries in my gaming laptops. I never keep it from the wall anyway, and I can live without that 2-3 hours of battery life.

The first thing I did when I got my Nitro 5 is remove the battery and stuffed it back in the box, never to see the light of day again. Would recommend if your laptop just sits attached to an outlet all the time.
