What's the real reason that laptop batteries are made not-accessible?

Inside a laptop or cell phone, the battery case is the chassis. If you allow a pouch battery to be taken out of the chassis easiliy, you'll have to protect the fragile battery with an additional layer of plastic/case. In addition: no you can't make it fit tightly as batteries swell as they discharge.

That's a pretty poor argument as there *are* plenty of machines with removable batteries. If this was indeed a thing, "criminals" could simply bypass all these clever law enforcement types and pick out a laptop with a removable battery.


--- Quote from: Ben321 on December 03, 2021, 02:59:50 am ---Simplest design is to make sure that the farthest back component in the laptop's case (closest to the removable panel back panel of the case, so as to have direct access to it after the panel is removed) is the battery. How hard is that? Just make sure there are no PCBs between the battery and the removable panel. Not exactly a major engineering achievement. If it's NOT the closest thing to the removable panel, then you can be sure the companies are trying to deter the end user from trying to remove it.

You seem to assume the only design achievement the engineers need to worry about is making the battery easily accesible. I'm guessing they may have one or two other goals on their checklist.

I wonder why the batteries are failing so quickly? I replaced the battery once in my iPhone 4 before the phone got so slow due to software bloat that it was no longer viable to use. My current iPhone SE is still on the original battery although it's starting to get to the point where I'll be considering putting a new one in there sometime in the next year or so. That's one failed battery and one retired due to phone replacement in a ~10 year period.

Ever increasing charging speed?
David Hess:
1. User replaceable batteries increase liability in the event of a destructive fault.  If the user has to disassemble the device to change the battery, then more fault can be applied to them.

2. Integrated batteries are less expensive.

3. Integrated batteries encourage planned obsolescence.

Pouch batteries have a shorter life than cylindrical batteries because of their physical construction.

What does that have to do with this? Both of my iPhones use pouch batteries, just like the Samsung device mentioned.

And as I mentioned earlier in the thread, I have an iPhone 6 from 2014 and it's original battery is still showing 92% capacity.

I imagine to wear out a battery enough to need replacing you would have to charge/discharge it several times per day?
