Replacement for Dell Vostro and Inspiron

This new six-cell lithium-ion battery delivers 10.8 volts and 4400 mAh capacity for compatible Dell laptops. It suits owners of listed Vostro and Inspiron models who need a direct replacement for an ageing original pack. The black housing matches the factory appearance and fits the existing battery bay without modification.

Built-in protection chip and one-year coverage

The integrated smart control chip manages charging current, reduces power draw and extends discharge time during use. It also provides short-circuit, overheat and overload safeguards so the pack operates safely in daily conditions. A one-year manufacturer warranty backs the cell quality and assembly.

Verify model number and voltage before ordering

Check the part number printed on your current battery against the 312-series codes such as 312-0234, 312-0235, 312-0239, 312-0240, 312-1180, 312-1197, 312-1198 and 312-1200. Confirm that your original pack is rated at 10.8 volts and uses a six-cell layout. Buyers whose laptop requires a different voltage, cell count or connector layout cannot use this unit.

Questions about this item

When will the 6-cell lithium-ion pack need replacing?

The 4400 mAh / 48 Wh capacity will gradually decline with normal daily cycling; plan on a replacement once run-time drops below your needs.

What stops the battery from running longer on a heavy workload?

The fixed 4400 mAh capacity is the hard limit; sustained high draw simply depletes the available charge faster.

Does the pack get hot or draw extra power during all-day use?

The built-in smart control chip manages charging and discharge to limit heat, while over-heat and overload protections keep temperature and power draw in check.
