Both chargers & batteries came the 15th. Plugged in the AAA as a test, think it may work unless they won't hold a charge too long.Okay you convinced me, I just ordered a rechargeable setup for both the AAA & AA battery packs with chargers. A triple 'AAA' for the keyboard which I do like & a dbl 'AA' setup for the Logitech M510 mouse that I also like for my All-In-One. Now I no longer have a new/unused Mouse & Keyboard combo. Thanks to 'Mint' & UPS.
Decided to return the wired KB & mouse unopened since my last order hasn't been shipped. Easy, Peasy!
