Direct replacement for Dell Inspiron and Vostro
This 56Wh lithium-polymer battery operates at 15.2V with a 3500mAh capacity. It matches part numbers 33YDH, 99NF2, PVHT1, 81PF3 and 081PF3. The black unit fits Inspiron 13, 15 and 17 models plus Vostro 15 series laptops.
Normal thermal and power behaviour
Li-polymer chemistry delivers stable voltage across the discharge cycle with minimal heat rise during typical workloads. No active cooling is required and the pack adds no audible noise. Power draw follows the host system's demand without extra overhead.
Restores original runtime without extra software
The battery installs directly and is recognised by the system firmware immediately. No drivers, utilities or calibration tools are bundled or required. Buyers needing higher capacity than 56Wh or a different voltage should look elsewhere.

Questions about this item
How do I install the 33YDH battery in my Inspiron 15 7577 and what step is often missed?
Power off the laptop, disconnect the AC adapter, remove the base screws, detach the old pack connector, fit the new 56Wh unit, reconnect the cable, reassemble the chassis, then charge fully before first use.
What maintenance or replacement will the 33YDH Li-polymer pack need over time?
No scheduled maintenance is required; the 15.2V 3500mAh pack should be replaced when runtime no longer meets your workload.
What limit appears first on the 33YDH during sustained heavy use?
The 56Wh capacity determines how long the battery can power the system before the voltage drops and the laptop throttles or shuts down.
