Battery Pack Retention Systems for Mobile Computing Devices

A computing device includes: a housing defining a battery chamber; an electrical contact disposed on a wall of the battery chamber; a latch extending into the battery chamber, the latch movable between (i) a first position to retain a battery pack within the battery chamber and engage the battery pack with the electrical contact, and (ii) a second position to disengage from the battery pack; an auxiliary retainer in communication with the battery chamber, the auxiliary retainer configured to retain the battery pack within the battery chamber, independently of the latch, via engagement with a complementary retaining structure of the battery pack.
