Frequently Asked Questions
Q: Is this battery larger than the original 61 or 61+?
A: Yes, the 61++ is a 6-cell extended battery. It will protrude slightly from the bottom, which tilts the laptop forward for better ergonomics and cooling.
Q: Does this fit the T480s?
A: No. The “s” models (like T480s/T470s) use an entirely different internal battery. This is for the standard T480/T470 series.
