Questions about this item

Does this 72WHR GreenTech battery fit my ThinkPad T480 without any extra hardware?

Yes, it replaces OEM part 4X50M08812 and fits the T480 directly; no additional parts are needed.

Will the 10.8V 6-cell pack charge correctly if I keep my older 61++ battery as a spare?

Both batteries use the same 10.8V 6-cell design, so the laptop's charging circuit handles either pack without adjustment.

How can I confirm the 6600mAh capacity is working after I install it?

Check the reported capacity in Lenovo Vantage or the BIOS power section; it should show roughly 72WHR when fully charged.
