You're still talking past me. A standard form factor won't solve the trust problem.

Most people don't know how to choose a proper hard drive compatible with their M.2 adapter or cable for their USB device. Many people also buy counterfeit USB sticks and SSDs that don't have near the capacity they advertise. You and other tech-literate people aren't the only consumers manufacturers are selling to. Nor are people always sufficiently educated, or living among stores with sufficient reputation to source from a reputable aftermarket vendor for their replacements.

Look, I'm really not sure where you are coming from. Batteries are solved problem since 1920. It's just gadget and computer manufacturers that suddenly see a way to make a uick buck and to drive their cycle of planned obsolescence.

If I could do it at 6 and my mom can do it at close to 80 then I really don't see why other people could not. Sometimes there just isn't a problem unless you make one. Standardize the cells, sell them through the supermarket chains at a normal price, just like Duracell and other quality battery manufacturers have been able to do for ages. Problem solved, once and for all. No need to go through AliExpress, Amazon or some other shady online store, if you are that concerned about trust then the only way to solve that is to buy from a reputable vendor.

The trust problem is better solved by relevant legislation. The counterfeit problem is better solved by relevant legislation. Intentional incompatibility with generic replacement parts will eventually also be solved by, you guessed it, relevant legislation.

It would give reputable battery producers with all kind of certificates a thing and not buying dubious compatible batteries from Amazon/EBay/Ali/whatever a thing.

It would also make it easier for people to learn how to replace batteries.
