Direct replacement for Everex StepNote series

This 11.1 V lithium-ion battery delivers 4400 mAh capacity and matches the original specifications for StepNote VA250, NC1501, NC1502, VA4101M, NC1503, VA2000, VA4100M, VA2001T, NC1510 and VA4103 models. It is built to the same dimensions of 208.0 x 48.0 x 21.2 mm and weighs 433.6 g, ensuring a precise fit inside the laptop chassis. The cell chemistry and voltage are identical to the factory pack, so the system recognises it without firmware updates or calibration steps.

Built-in protection keeps thermals and draw stable

Overcharge, over-discharge, over-voltage and short-circuit safeguards are integrated into the pack, preventing excessive current flow that would raise temperature or stress the laptop's charging circuit. In normal use the battery maintains steady voltage output without triggering thermal throttling or fan spin-up beyond typical levels. The protection circuitry also limits self-discharge during storage, so the pack retains usable charge for longer periods between sessions.

Certified safety standards replace guesswork

The pack carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications, confirming compliance with international quality, hazardous-substance and transport regulations. No separate driver, monitoring utility or calibration tool is bundled; the laptop's existing power management handles all communication through the standard smart-battery interface. Buyers who need a higher-capacity cell or a different voltage for extended runtime will not find those options in this listing.

Questions about this item

How do I install this battery in my Everex StepNote VA250 and what step is often missed?

Power off the laptop, unplug the AC adapter, slide the release latch, remove the old pack, insert the 208.0 x 48.0 x 21.2 mm replacement until it clicks, then charge fully before first use.

What maintenance will this 11.1V 4400mAh Li-ion pack need over its life?

Store at roughly 50 % charge if unused for weeks, avoid deep discharges, keep contacts clean, and replace the pack once runtime drops below your needs.

What limit appears first during sustained heavy loads on this 433.6 g battery?

Thermal protection will throttle output before the 11.1 V nominal voltage sags excessively, preventing overheat and preserving cell health.
