Battery Care Tips
Battery Care Tips
🔹 Getting Started
Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.
🔹 Keep It Healthy
Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.
Delivery and Shipping
Delivery and Shipping
🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Compaq Evo N410C Series — 14.8V Li-ion Replacement Battery (292389-001)
This 14.8V Li-ion battery replaces the original pack in Compaq Evo N410C laptops, including the N410C-470039-399, -509, -584, and -679 configurations. Capacity is 2200mAh (32.56Wh), matching the original spec. OEM part numbers covered include 292389-001, 213282-001, 291693-001, 235596-001, 232593-B25, 293343-B25, and 231445-001.
- Evo N410C battery platform: All N410C variants in this cluster share the same 14.8V four-cell series configuration, connector pinout, and BMS communication protocol — that is why one cell covers the full range of sub-models listed.
- Bench tested on actual hardware: We ran this cell through a full charge-discharge cycle and verified the BMS handshake. The protection circuit tripped correctly at low-voltage cutoff and accepted charge without issue from the N410C's onboard charging circuit.
- First-cycle calibration on the Evo N410C: After installing, discharge the laptop to hibernate cutoff under normal use — screen on, a background task running — then charge uninterrupted to 100%. This gives the BIOS fuel gauge IC a reference point against the new cell and clears the inaccurate health warning that appears after every cell swap.
Why the Evo N410C shuts down at 20–30% shown remaining
The N410C's fuel gauge reads state-of-charge based on a voltage curve mapped to the previous cell's age and internal resistance. A new cell has a steeper voltage cliff near depletion — the system reads 25% but the cell voltage drops below the BMS cutoff threshold faster than the gauge expects. The result is an abrupt shutdown with charge still showing on screen. One full calibration cycle — discharge to hibernate, full uninterrupted recharge — corrects the voltage-to-percentage mapping and eliminates the early cutoff.
BIOS reporting battery health as poor immediately after replacement
The Evo N410C reads battery health data from EEPROM fields written by the original cell, including cycle count and design capacity. A new cell ships with EEPROM values that differ from the aged pack the BIOS last learned, so Windows and the BIOS both flag health as unknown or poor on first boot. This is a calibration state, not a fault. Run one full discharge-to-hibernate and charge-to-100% cycle — the BIOS learn cycle rewrites its reference data against the new cell and clears the warning.

Frequently Asked Questions
The Evo N410C fuel gauge is jumping around — showing 60%, then 40%, then 80% within minutes of each other. Is the new battery faulty?
The fuel gauge IC on the N410C needs two or three full cycles against a new cell to build an accurate charge map. The erratic readings are the IC interpolating between stale EEPROM data from the old pack and actual voltage readings from the new chemistry. It is not a cell fault. Discharge to hibernate cutoff, charge uninterrupted to 100%, and repeat once more — the gauge stabilises after the second full cycle.
Windows shows the Evo N410C battery as 32Wh but the system info screen is displaying a completely different Wh figure — why does it not match?
The Wh figure in system info is pulled from EEPROM data embedded in the cell, which records rated design capacity at manufacture. The 32.56Wh value in the product spec reflects actual measured capacity of the cells installed. These two figures come from different sources and a small discrepancy is normal. If the displayed value is wildly off — more than 10Wh — run a full discharge-to-hibernate then charge-to-100% cycle so the BIOS recalculates against real charge throughput.
The replacement battery charged to 100% once, but now it stops charging at 78–80% every time. Nothing changed in the settings.
Some Evo N410C BIOS versions include a charge limit threshold that activates after the first cycle — it is a firmware-controlled ceiling, not a cell problem. Check the BIOS power management screen (F10 at POST) for a battery charge limit or conservation mode setting and disable it. If no such setting exists, update the system BIOS to the latest Compaq-released version for the N410C, as early firmware revisions have a known charge ceiling bug that was patched in later releases.
