That advice is always correct, except when it isn't.
Designers sometimes do stupid things to reduce costs.
Sometimes advisers extrapolate their experience to situations
where it doesn't apply and express it with arrogance.

Check out the schematic for a Compaq Aero 4-25.
The only thing between the battery and the charge jack is a FET switch.
They use the current limit in the power brick to limit the charge
current.  If you use a charger with a higher current limit, you overheat
the battery.
If you use an unlimited current source, the FET catches fire.
Somewhere around here I have a motherbord with a hole burned in it.

Expressing advice concisely and completely with maximum arrogance
to a newbie without a voltmeter or the
means or understanding to verify the advice is irresponsible...
even if it is correct ALMOST all of the time.
Sometimes, the advice doesn't apply.
