    Anyone aware of any downsides to Lenovo's Rapid Charge technology? For example, do the batteries that support this last just as long as those that do not? These days, you are lucky to get 3 years out of most lithium batteries and by then they usually don't hold a full charge.

    I'm interested in knowing that as well. The X301 6-cell battery I have is 4 years old and still holds 95 % charge, so I guess not all batteries are dead after 3 years. But maybe if you use RapidCharge, they will be.

    I would guess Rapid Charge is based on changes baked into the firmware of the batteries. Some automotive batteries use a similar system and it does not affect the lifetime of the battery. As such, I would guess that Rapid Charge is similarly safe.

    batteries must be formulated specifically to support rapid charging.   you can't rapid charge standard batteries without negative effects.

    This also explains why Lenovo put a hardware lock on the new systems so they don't attempt to rapid charge batteries that aren't designed for it.
