3-cell 41 Whr Dell replacement battery

This new Total Micro Technologies battery supplies 41 Whr at 11.25 V with a 3645 mAh rating across three cells. It fits a wide range of Dell Latitude and Vostro models including the 3320, 3330, 3420, 3520, 3530 and 3140 series as well as Vostro 14 and 15 inch variants such as the 5410, 3510 and 3515. The pack restores original run-time for daily office work and web browsing.

Capacity and runtime limits

The 41 Whr capacity comfortably powers typical productivity tasks for several hours depending on screen brightness and workload. Heavy multi-tasking, sustained video playback or discrete graphics loads will drain the pack more quickly and may require a mid-day recharge. Buyers needing all-day autonomy without access to a charger should consider a higher-capacity alternative if their chassis supports it.

Questions about this item

Will the 41Whr 11.25V pack fit a Latitude 3320 that originally shipped with a smaller 3-cell battery?

The pack is listed for Latitude 3320 among other models; the 3-cell 41Whr 11.25V specification matches the original Dell part for that chassis.

How can I confirm the 3645mAh cell is charging correctly after installation?

In the OS battery report check that design capacity reads 41Whr and full-charge capacity reaches the same value after a complete charge cycle.
