Direct replacement for Dell V6VMN 21X15 P26S001

This new lithium-ion battery delivers 55Wh at 7.6V using four premium cells. It is built as a direct replacement for the listed Dell part numbers and carries CE and RoHS certification. Buyers who need a different voltage or a higher capacity will not be served by this unit.

Fit and safety certifications change the risk

The CE and RoHS marks confirm the pack meets European safety and environmental standards. The supplier notes there are two different batteries for the same laptop model that are not interchangeable, so matching the part number against the original is the only way to guarantee fit.

Simple swap but part-number mismatch is the common

Installation requires removing the old pack and fitting this one in the same bay; no tools beyond a standard screwdriver are typically needed. The most frequent problem is ordering the wrong variant because the laptop model accepts two incompatible batteries.

Questions about this item

How many charge cycles before the 4-cell lithium-ion pack needs replacement?

The battery uses a 4-cell lithium-ion design rated for typical cycle life; capacity will gradually decline after several hundred full cycles.

What limits runtime first during a continuous heavy workload?

The 55 Wh capacity sets the energy ceiling, so sustained high draw depletes the charge fastest.

Does the 7.6 V pack run hot or draw extra power when the laptop is on all day?

Normal operation stays within thermal limits; the lithium-ion chemistry and CE certification keep heat and self-discharge low during extended use.
