Professional Series replacement

This Dr. Battery Professional Series unit replaces the original pack in Dell Latitude 5420, 5520 and Precision 3560 laptops. It uses lithium-polymer cells rated at 15.2V and 3000mAh to restore mobile power for business and everyday workloads. The pack measures 8.0x1.5x0.8 and weighs 0.4, matching the factory form factor.

Voltage and capacity limits

The 15.2V output is fixed by the cell chemistry and cannot be adjusted for other platforms. Capacity is limited to 3000mAh, so runtime scales directly with the host system's power draw and cannot be extended without a higher-capacity pack. Built-in circuitry stops charging at the safe voltage threshold and cuts discharge before the cells reach a critical low point.

Internal fit and common issues

Installation requires opening the chassis and disconnecting the old pack, so basic disassembly skill is needed. The connector keying matches the listed Dell part numbers, but forcing the plug can damage the motherboard header. Swelling or failure to charge usually points to a worn charging circuit rather than the battery itself.
