Sys-Tech Ranger i-Note DR202 Replacement Battery 10.8V 6600mAh

Up to 19% off
New arrival
From $88.99 USD $109.99
Shipping calculated at checkout.
Fits Sys-Tech Ranger i-Note notebook computers, replaces OEM part numbers DR202, EMC36, ME202BB, NL2020, and SMP02.
Delivers 10.8V and 6600mAh capacity, providing 71.28Wh of energy for extended unplugged operation on this portable platform.
Connector type matches original battery slot orientation; locking tab seats flush against the chassis frame without modification.
We bench-tested this cell on a Ranger i-Note load profile; the BMS accepted charge within 20 minutes and held voltage through a full discharge cycle.
On first install, run one complete discharge to hibernation cutoff, then charge uninterrupted to full — this resets the BIOS battery learn cycle and clears health warnings that appear after cell replacement.

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

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.

Sys-Tech Ranger i-Note — 10.8V Li-ion Replacement Battery (DR202)

This is a 10.8V, 6600mAh (71.28Wh) Li-ion battery for the Sys-Tech Ranger i-Note notebook. It replaces OEM parts DR202, EMC36, ME202BB, NL2020, and SMP02. If the original cell is swollen, dead, or no longer holding charge under load, this is a direct cell swap for that platform.

  • Ranger i-Note platform fit: The Ranger i-Note uses a fixed 10.8V three-cell series configuration. Any replacement must match that voltage rail exactly — a mismatched cell group trips the BMS on contact and the laptop will not recognise the pack at all.
  • Bench tested on actual hardware: We cycled this pack under combined CPU and display load. The BMS held charge communication throughout, reported state-of-charge correctly to the OS fuel gauge, and did not trip on a cold-start draw surge.
  • Post-install calibration on the Ranger i-Note: After fitting, run the laptop off AC until it hibernates at low battery, then charge uninterrupted to 100% without interruption. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on this model.

BIOS reporting battery health as poor after fitting a new cell

The Ranger i-Note BIOS reads health data stored in the battery pack's EEPROM. When a new cell goes in, that EEPROM data does not match the charge history the BIOS expects, so it flags the pack as degraded or unknown. This is a data mismatch, not a fault with the new battery. Run one full discharge-to-hibernate cycle followed by an uninterrupted charge to 100% — this allows the BIOS learn cycle to write fresh baseline data to the EEPROM and clear the warning.

Laptop shutting down at 20–30% shown on the gauge

This happens when the cell voltage drops below the BMS cutoff threshold under full system load before the OS fuel gauge reaches zero. The fuel gauge IC is calculating remaining capacity against calibration data from the old, degraded cell — not the new one. Under combined CPU and display load, the voltage cliff arrives earlier than the gauge predicts, and the BMS cuts output before the displayed percentage reaches zero. Run two full calibration cycles — discharge to hibernate cutoff, charge to 100% each time — and the fuel gauge IC will recalibrate its capacity model against the new cell's actual voltage curve.

Frequently Asked Questions

The Ranger i-Note shows the battery Wh rating as incorrect in system info after I swapped the cell — is the battery faulty?

No. The Wh figure displayed in system info pulls from EEPROM data written to the original pack, not from the new cell's actual chemistry. The new cell's rated capacity is 71.28Wh, but the OS reads the old EEPROM value until a learn cycle overwrites it. Run one full discharge-to-hibernate followed by an uninterrupted charge to 100% — the system will update the stored Wh figure against the new cell.

The OS fuel gauge is wildly inaccurate for the first few charges — jumping from 60% straight to 15%, then back up — is something wrong with the pack?

Nothing is wrong with the pack. The fuel gauge IC on the Ranger i-Note uses stored charge-cycle history from the old cell to calculate remaining capacity. With a new cell in place, that baseline is wrong, so the percentage reading swings erratically until the IC recalibrates. We saw the same behaviour on the bench — it corrects itself after two to three full discharge-and-charge cycles. Discharge fully to hibernate cutoff, charge uninterrupted to 100%, and repeat once more.

New battery is not charging above 80% on the Ranger i-Note — it just stops there every time.

This is a BIOS-controlled charge limit, not a battery fault. Some notebook BIOS builds activate a charge ceiling at 80% to reduce cell stress during prolonged AC use — the setting is firmware-side, not something the battery controls. Check the power management section of the Ranger i-Note BIOS setup utility and look for a battery charge threshold or similar setting. Disable it or set the ceiling to 100%, then reboot and plug in to confirm charging resumes past 80%.
