6-cell 5200 mAh Li-ion battery for Dell laptops

This replacement battery fits Dell Inspiron 1520, 1521 and 1721 models as well as Vostro 1500 and 1700 systems. It delivers 11.1 V from six lithium-ion cells rated at 5200 mAh. The unit is new and carries CE and FCC safety certifications with built-in circuit protection.

Direct swap installation with part-number matching

The pack is designed as a direct swap for the original Dell modules listed under part numbers such as W280, 0UW280, NR239, 312-0589, 451-10477, FK890, GK479, 312-0504, 312-0575, 312-0576, 312-0590, 312-0594 and FP282. Installation requires only removing the old battery and fitting this one in the same bay. The main risk is ordering the wrong variant, so verify the exact part number printed on your current battery before purchase.

5200 mAh capacity for typical daily workloads

At 5200 mAh the pack supports ordinary office tasks, web browsing and media playback for several hours on a full charge. Runtime will fall with heavy CPU or GPU load, high screen brightness or attached peripherals. It is not suited for users who need all-day operation away from mains power without recharging.

Questions about this item

How can I confirm the 11.1 V 5200 mAh battery is recognised correctly by my Inspiron 1520 after installation?

Insert the pack, boot into the BIOS and verify the reported voltage reads 11.1 V and the capacity shows 5200 mAh; the Dell power manager should then display normal charging and discharging cycles.

What is included with the PISKEKAT 6-cell pack and do I need a separate charger for my Vostro 1500?

The box contains only the 6-cell Li-ion battery; your existing Dell AC adapter charges it normally so no extra charger is required.

Which part-number version should I choose for a Dell Inspiron 1721 — W280, 0UW280 or 312-0589?

All three part numbers (W280, 0UW280, 312-0589) are listed as compatible with the Inspiron 1721, so any of them will fit and work correctly.
