KingSener G91J0 41Wh laptop battery for Dell Inspiron 5515 5625 5410 7415 Latitude 3320 Vostro 5620 5625

Direct replacement for Dell laptops

The KingSener G91J0 is a new 41 Wh lithium-ion battery built for Dell Inspiron 5515, 5625, 5410, 7415, Latitude 3320 and Vostro 5620, 5625 models. It delivers 3467 mAh at 11.25 V using cells made in China and matches the original dimensions for a tool-free swap.

Upgrading from a worn original

This unit replaces a factory battery that no longer holds a useful charge or that shuts down under load. The jump is worth it when run-time has dropped below half of the design capacity or when the system reports a permanent failure code. It is not for buyers who want a higher-capacity pack than the 41 Wh specification.

Limits of the 11.25 V lithium-ion format

Capacity will fade with each full cycle and the pack must not be left at full charge while continuously plugged into mains power. Storage above 80 % charge for longer than a month accelerates ageing, as does exposure to hot or humid environments. The battery cannot be repaired, punctured or disposed of in fire or water.
