Dr. Battery MPL05240P-20 6-cell 10.8V 4400mAh laptop battery

Replacement for Dell Vostro and Inspiron models

This 6-cell lithium-ion battery replaces the original power pack in a wide range of Dell Vostro and Inspiron laptops. It delivers 10.8V and 4400mAh for a total of 48Wh. The unit is new and carries a one-year warranty. A built-in smart control chip manages charging and protects against short circuit, overheat and overload.

Voltage and capacity define the practical limit

The 10.8V output and 4400mAh capacity set the energy budget for each charge cycle. Runtime will vary with the laptop's power draw, screen brightness and workload. The smart chip enables quicker charging and lower power consumption during use. No higher-capacity option is offered in this form factor.

Upgrades worn or failed original packs

This battery replaces an ageing or defective OEM unit that no longer holds sufficient charge. The jump is worth it when the original pack gives only minutes of runtime or triggers shutdown under load. It is not for buyers who need a higher-watt-hour design or a different voltage. Always verify the exact model number and voltage before purchase.
