The part number for the US Battery US185HCXC changed to [US185HCXC2](https://www.batteriesinaflash.com/aut...) but is still the same battery with some performance updates in the design. However, if one battery is bad then you should typically replace them all or the older batteries will run down your new battery very quickly causing you to end up replacing them all.
