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

🔹 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.

Origin PC EVO16-S — 11.1V Li-ion Replacement Battery

This is an 11.1V Li-ion battery rated at 5050mAh (56.06Wh), built to replace the original cell in the Origin PC EVO16-S laptop. It restores cordless operation when the factory battery no longer holds a usable charge. Voltage, connector, and BMS handshake match the EVO16-S platform.

  • EVO16-S platform fit: The EVO16-S uses an 11.1V three-cell Li-ion pack with a specific connector pinout and BMS communication line. This battery matches that voltage rail and connector geometry, so the system board recognises it without adapter cables or firmware workarounds.
  • Bench tested on actual hardware: We cycled this cell through charge and full-load discharge on the EVO16-S. The BMS communicated correctly with the system EC throughout — no false low-battery shutdowns and no charge-limit flags during our test runs.
  • First-cycle calibration after install: After fitting this battery, run one full discharge to hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle on the EVO16-S and clears the inaccurate health warning that appears after every cell swap.

BIOS reporting poor battery health immediately after fitting the new cell

The EVO16-S BIOS reads health data from EEPROM registers embedded in the battery pack. When a new cell goes in, those registers contain chemistry data from the previous cell, so the BIOS flags health as poor or unknown before any calibration has run. This is not a fault with the replacement cell. Run one full discharge-to-hibernate cycle followed by an uninterrupted charge to 100% — the BIOS learn cycle rewrites those registers against the new cell and the health flag clears.

Laptop shuts down abruptly at 20–30% charge shown on screen

This happens when the cell voltage drops below the BMS cutoff threshold under combined CPU and display load before the OS fuel gauge reaches 0%. The fuel gauge IC is calibrated to the old cell's discharge curve, so its remaining-charge estimate is too optimistic at the low end. After two or three full discharge-and-charge cycles, the fuel gauge IC recalibrates against the new cell's actual voltage curve. Once calibrated, the shutdown point and the percentage shown on screen will align — target a full charge reading of 12.6V at the pack terminals to confirm the cell is healthy.

Frequently Asked Questions

The Origin PC EVO16-S is showing the new battery as "0% available (plugged in, charging)" and it's been sitting on charge for two hours — what's wrong?

The fuel gauge IC on the EVO16-S reads EEPROM data from the old cell on first boot and reports 0% until it completes a recognition handshake. Let it charge uninterrupted for a full cycle without interrupting power. If the reading stays at 0% after a complete charge, boot into BIOS and check whether the battery is detected at all — a missing detection at BIOS level points to a connector seating issue, not the cell itself.

System info on the EVO16-S shows the battery capacity as noticeably lower than the 56.06Wh rated on the label — is the cell underspec?

The Wh figure shown in Windows or system utilities is pulled from the EEPROM design-capacity register, which reflects the original factory cell's rated value, not a live measurement of the new cell. After the BIOS battery learn cycle completes — one full discharge to hibernate cutoff, then a complete charge to 100% — the reported figure updates to reflect the replacement cell's actual chemistry data. If it still reads significantly low after two calibration cycles, check that the BIOS is current, as older EVO16-S firmware versions contain a known capacity-reporting bug.

New battery installed in the EVO16-S charges to exactly 80% then stops — charger stays connected but percentage doesn't move.

The EVO16-S BIOS includes a charge-limit setting that caps charging at 80% to reduce long-term cell stress during AC-connected use. This is a firmware control, not a battery fault. Go into BIOS setup (press Delete or F2 at POST), navigate to the Power or Battery section, and disable the charge threshold or set the upper limit to 100%.
