40 Wh 14.8 V Dell Inspiron battery
This new lithium-polymer replacement battery delivers 40 watt-hours at 14.8 volts for a wide range of Dell Inspiron 14, 15 and 17 models across the 3000 and 5000 series. It also fits select Vostro and Latitude notebooks and matches a long list of original Dell part numbers.
2600 mAh capacity decides fit
The single figure that determines whether this is the correct part is the 2600 milliamp-hour rating combined with the 14.8 V output; if the original battery shows the same voltage and capacity, the upgraded internal PCB ensures full compatibility without model-year restrictions.
Handles daily mobile workloads
A 40 Wh pack comfortably powers typical office tasks, web browsing and video playback for several hours on a single charge; it will run out sooner under sustained heavy loads such as gaming or video rendering, where higher-capacity alternatives would be required.

Questions about this item
How long will the 40Wh capacity last in a real laptop?
The 40Wh rating means the pack stores forty watt-hours of energy; actual runtime depends on the laptop's power draw, so a system drawing twenty watts would run roughly two hours on a full charge.
What does the 14.8V rating mean for charging and use?
The battery operates at 14.8 volts nominal, matching the original Dell specification; the laptop's charging circuit manages voltage and current, so no external adapter change is needed.
Will the 270g pack with dimensions 14.33in W x 12.83in H x 9.06in D fit my Inspiron bay?
Those are the shipping carton dimensions; the cell pack itself is designed to the original M5Y1K form factor and fits the listed Inspiron 14, 15 and 17 models without modification.
