Q: What is a modular bay battery?
A: In some laptop systems Dell offers a battery that can be used in the optical drive media bay (DVD/CD drive bay). This enables the use of two batteries, potentially extending the available run time.
Q: If I install a modular bay battery, are my primary and modular bay batteries working at the same time to power my laptop computer?
A: No, the modular bay battery is used first, then the system automatically switches to the primary battery. This is a deliberate design to allow the most amount of run time to remain in the primary battery in case the modular bay battery is removed and replaced with an optical drive.
