Direct replacement battery

This PISKEKAT 0PD19 battery replaces the original power cell in Dell Inspiron 14 and 15 models including 5442, 5443, 5445, 5447, 5448, 5457, 5542, 5543, 5545, 5547, 5548 and 5557 as well as Latitude 3450 and 3550. It suits owners who need a new 4-cell lithium polymer pack to restore mobile runtime. Buyers whose laptops use a different connector or voltage should look elsewhere.

Thermals and power draw

The pack delivers 7.4 volts and 58 watt-hours from a 7410 milliampere-hour capacity. Lithium polymer chemistry keeps self-discharge low during storage and provides stable voltage under typical office workloads. No active cooling is required because the battery sits inside the chassis and relies on the laptop's own thermal design. Press the connector firmly during installation so the system recognises the pack immediately.

Build integration

The battery fits the existing bay in the listed Inspiron and Latitude chassis without modification. Its 4-cell layout matches the original form factor, leaving all ports, drives and expansion slots accessible. The package contains one brand-new cell and no additional cables or tools. Users replacing a 11.1 volt 43 watt-hour unit such as the TRHFF should verify the voltage label before fitting.

Questions about this item

How do I install the 0PD19 battery and what step is often missed?

Remove the old pack, align the 7.4V 58Wh unit with the Dell Inspiron or Latitude bay, then press the connector firmly until it clicks; a loose fit causes the laptop not to recognise the battery.

What maintenance or replacement will the 4-cell Li Polymer pack need later?

The 7410mAh cells slowly lose capacity over repeated charge cycles; plan to swap the battery when run-time no longer meets your daily workload.

What limit appears first during sustained use of this 7.4V 58Wh battery?

The 58 watt-hour capacity sets the maximum run-time per charge; under continuous load the pack will deplete before any thermal or voltage limit is reached.
