Compatible Dell Laptop Battery

The Total Micro 1WND8TM is a 3-cell 31.5Whr 11.4V replacement battery built for select Dell laptop models. It meets or exceeds OEM specifications to restore original runtime. The unit is supplied new and ready for immediate use.

Upgrade From Worn Original Cells

This battery replaces a factory pack that no longer holds a useful charge or that shuts down under load. The jump is worth it when the laptop runs only minutes on battery or refuses to start without AC power. It is not for buyers who need a higher-capacity pack or a different voltage for another chassis.

Straightforward Internal Swap

Installation requires opening the laptop case, disconnecting the old pack, and connecting the new one using the existing cable. What usually goes wrong is forgetting to detach the AC adapter first or seating the connector incompletely, which prevents the system from recognising the battery.

Questions about this item

Will this 11.4 V, 31.5 Whr battery fit my Dell laptop chassis?

It is built to the same physical dimensions as the original Dell pack it replaces, so it slides into the same battery bay without modification.

What is the correct way to install the 1WND8TM battery?

Power off the laptop, disconnect the AC adapter, release the retention latch, insert the pack until it clicks, then charge fully before first use.

When should I replace this 3-cell 31.5 Whr battery?

Replace it when a full charge no longer powers the notebook for a useful session or the system reports a permanent capacity loss.
