Replacement battery for Dell laptops

This Dr. Battery MPL05308P-29 lithium-polymer unit delivers 11.4 V and 3400 mAh capacity. It is built as a direct replacement for a wide range of Dell Inspiron and Latitude models, including 13, 14, 15 and 17 inch variants. The pack includes a smart control chip that manages charging and provides short-circuit, overheat and overload protection.

Suitable for owners of listed Dell models needing

Buyers who cannot confirm their original battery part number or output voltage should not purchase this unit. It is not for users whose laptop requires a different voltage, connector layout or physical dimensions than the original Dell specifications. Anyone needing an external power bank or AC adapter should look at a different product category.

11.4 V 3400 mAh lithium-polymer specification

The single decisive figure is the 11.4 V output combined with 3400 mAh capacity in a lithium-polymer form factor. If the original battery shows a different voltage or a substantially different milliampere-hour rating, this pack will not be compatible. Matching those two numbers to the original Dell battery is the only way to confirm fit.

Questions about this item

How does the 3400 mAh rating translate to actual use?

The 3400 mAh capacity at 11.4 V supplies roughly 42 Wh of energy, matching the manufacturer's stated 3500 mAh / 42 Wh figure; real runtime varies with screen brightness, workload and system power management.

What connector standard does this battery use and what does it limit?

It uses the proprietary Dell battery connector for the listed Inspiron and Latitude models; the interface limits use to those specific Dell laptops and prevents cross-brand installation.

What physical checks are needed before fitting this pack?

Compare the pack's shape, screw-hole positions and label orientation with your original battery; the product is designed for the Dell models listed in the compatibility data.
