Dell 4R084 modular bay battery

Published on by Laptop Battery

For some laptop systems, the laptop manufacturers, such as Fujitsu & Dell, offer a battery that can be used in the modular bay (optical drive media bay such as DVD/CD drive bay) to extend your notebook’s battery life over the single battery configuration. This enables the use of two batteries for a laptop and potentially extends the available run time.

If a secondary modular bay battery is installed, it will be used first, and 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.

This is a 48 WHr 6-Cell Secondary Modular Bay Battery for Dell.
