56 Wh Dell replacement battery

This 56 Wh lithium-ion pack replaces the original 33YDH unit in a wide range of Dell Inspiron, G-series, Latitude and Vostro laptops.

Verify part number and model before ordering

Confirm that your laptop uses a 33YDH or PVHT1 type battery and that the voltage reads 15.2 V in the system information. The supported families include Inspiron 17 7000 and 7773, G3 3579 and 3779, G5 5587, G7 7588, Latitude 3380, 3490, 3580, 3590, 3400, 3500, Vostro 7570 and 7580. Cross-reference the printed P/N on your old pack with the list supplied by the vendor.

Sustained daily cycling performance

The cell chemistry is specified for over 1000 full charge-discharge cycles while retaining usable capacity. Under continuous load the pack maintains a steady 15.2 V output without the voltage sag seen in aged originals. Thermal behaviour stays within normal laptop operating limits during extended work sessions. Cycle life is maximised by avoiding deep discharges and storing at partial charge when unused for long periods.
