Battery for Dell G7 7590 and G5 5590

This 11.52V 3750mAh lithium-polymer cell replaces the original 4-cell pack in Dell G7 7590 and G5 5590 notebooks. It matches OEM part 7590-D1765B and carries China RoHS, Taiwan RoHS and WEEE certifications. The rechargeable battery is supplied new with an 18-month limited warranty.

Suits owners restoring runtime on compatible Dell

Buyers needing a different voltage, capacity or form factor should look elsewhere. The proprietary size fits only the listed G7 7590 and G5 5590 systems, so it will not work in other Dell series or third-party laptops.

Delivers steady 11.52V output during extended use

Lithium-polymer chemistry maintains consistent voltage through long discharge cycles rather than sagging after a short burst. The 3750mAh capacity supports prolonged mobile work between charges, and the pack is rated for repeated recharge cycles over its service life.

Questions about this item

My Dell G7 7590 currently uses a 4-cell 11.52 V 3750 mAh pack — does this battery match that exact specification?

Yes, this is a 4-cell lithium-polymer pack rated at 11.52 V and 3750 mAh, built to the same form factor as the original Dell 1F22N battery.

I plan to keep my older Dell G5 5590 as a backup machine — will this battery fit that model as well?

The part is listed as compatible with both the Dell G7 7590 and G5 5590 series, so it will work in either notebook.

After installing the battery, how can I confirm it is delivering the rated 11.52 V and 3750 mAh capacity?

Use the Dell Power Manager or BIOS battery health page; they will report the design voltage of 11.52 V and the full-charge capacity near 3750 mAh when the pack is functioning correctly.
