Direct replacement for listed Dell models

This 40Wh lithium-ion battery fits Dell Latitude 3410, 3510 and Vostro 5300, 5301, 5401, 5402, 5501, 5502. It operates at 11.25V and uses a four-cell design built to match the original form factor. Buyers who need a different capacity or a battery for models outside this list cannot use this part.

Thermals noise and power draw

Lithium-ion chemistry delivers steady output with minimal heat during typical office or media tasks. The pack draws only what the laptop requests, so fan behaviour and system temperatures remain unchanged from the original battery. No active cooling or acoustic profile is added by the battery itself.

CE and RoHS certified safety

The unit carries CE and RoHS certification, confirming compliance with European safety and environmental standards. A one-year replacement warranty covers defects in materials or workmanship. No software, drivers or additional accessories are bundled with the battery.

Questions about this item

How do I install the 40Wh JK6Y6 battery in my Dell Latitude 3410, and what step is often missed?

Power off the laptop, disconnect the AC adapter, remove the bottom case screws, detach the old battery connector before unscrewing it, fit the new 4-cell pack, reconnect the cable firmly, then reassemble.

What maintenance will this 11.25V lithium-ion pack need over its life?

No scheduled maintenance is required; avoid deep discharges, store at roughly half charge if unused for weeks, and keep vents clear so the cells stay cool during operation.

What limit appears first when the 40Wh battery runs under sustained load?

The 40 watt-hour capacity sets the runtime ceiling; continuous high draw will deplete the charge faster and generate heat that triggers the laptop's thermal throttling.
