Replacement Battery for Dell Inspiron

The 2-Power 3521 is a new 6-cell lithium-ion battery rated at 11.1 V and 5200 mAh. It is built to replace the original power pack in Dell Inspiron 1525, 1526, 1545, 1546, 1750 and 1440 models as well as Vostro 500 systems. The black casing matches the factory look and the cell chemistry is certified to CE, FCC and RoHS safety standards.

Fits Directly Into Existing Battery Bay

The pack slides into the same compartment used by Dell part numbers such as GW240, RN873, M911G, K450N and the 312-0625 series. No adapter cables or firmware updates are required; the laptop recognises the battery immediately. This frees the user from relying on a mains adapter when moving between rooms or working away from a desk.

No Extra Accessories Or Software Included

The box contains only the battery itself, so there are no driver discs, management utilities or mounting brackets to install. Buyers who need a higher-capacity 9-cell option or a 14.8 V 8-cell variant will not be served by this 11.1 V 6-cell design. Compatibility should be verified against the listed part numbers before purchase.

Questions about this item

How long will the 5200mAh capacity last before the battery needs recharging under continuous load?

The 5200mAh rating at 11.1V delivers 57.72Wh; actual run-time depends on the laptop's power draw, so a system averaging 20W would run roughly 2.9 hours on a full charge.

Does the lithium-ion pack generate noticeable heat or noise during all-day operation?

Lithium-ion cells produce no audible noise; warmth is normal during charge or heavy discharge but the pack has no fan and stays within safe limits for the certified 6-cell design.

Which Dell models or part numbers must the owner already have for this 3521 battery to fit?

It replaces part numbers such as GW240, RN873, 312-0625, 312-0626, M911G and fits Dell Inspiron 1525, 1526, 1545, 1546, 1750, 1440 plus Vostro 500.
