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.

ECS G730 / Green 732 — 14.8V Li-ion Replacement Battery (LIP-X036)
This is a 14.8V, 4400mAh (65.12Wh) Li-ion replacement battery for the ECS G730 and Green 732 notebooks. It slots into the same battery bay as the original LIP-X036 cell and restores mobile operation when the factory pack has degraded or failed entirely. Voltage and connector match the OEM specification exactly.
- G730 and Green 732 shared platform: Both models run the same 14.8V four-cell Li-ion bus, share the LIP-X036 connector pinout, and use the same BMS handshake protocol — which is why one replacement battery covers both. Swapping between these models requires no adapter or firmware change.
- Bench tested on actual hardware: We cycled this cell through charge, idle draw, and load discharge on the G730 platform. The BMS completed its initialisation handshake without error, and charge termination triggered correctly at full capacity with no trickle-loop fault.
- First-cycle calibration on the G730: After fitting this cell, let the laptop discharge fully until it hibernates, then charge uninterrupted to 100% without interruption. This single full discharge-to-hibernate cycle resets the BIOS battery learn sequence and clears the inaccurate health warning that appears on the first boot after any cell swap.
Why the G730 BIOS flags a new battery as poor health or unknown
The G730 BIOS reads battery health from EEPROM data written to the original cell at the factory. When a new cell is installed, that EEPROM data is either blank or mismatched, so the BIOS reports the pack as unknown, 0%, or degraded — even though the cell is new. This is not a fault with the replacement battery. Running one full discharge-to-hibernate cycle followed by an uninterrupted full charge gives the fuel gauge IC enough data to overwrite the stale EEPROM values and report correctly.
Laptop shuts down at 20–30% shown on the fuel gauge
This happens when the fuel gauge IC is still calibrated to the old cell's discharge curve. The displayed percentage and the actual cell voltage fall out of sync, and the BIOS triggers a protective shutdown before the gauge reaches zero. The fix is the same calibration cycle — discharge to hibernate-cutoff, then charge fully without interruption. After two to three full cycles, the fuel gauge IC re-maps its curve against the new cell and the early shutdowns stop. Check the battery percentage during a CPU-plus-display load cycle; if it stabilises after the second full cycle, calibration is complete.

Frequently Asked Questions
The G730 BIOS is showing this new battery as "unknown" or giving a 0% reading — is the cell faulty?
The cell is not faulty. The G730 BIOS pulls health data from EEPROM written to the original factory pack, and a new cell comes in with either blank or mismatched EEPROM values. Run one full discharge to hibernate-cutoff, then charge uninterrupted to 100% — this gives the fuel gauge IC enough real-world data to overwrite the stale values. After that single cycle, the BIOS should report the battery correctly.
My G730 is shutting down randomly at 20–30% remaining — did I get a bad battery?
This is a fuel gauge calibration mismatch, not a bad cell. The fuel gauge IC is still mapped to the old cell's discharge curve, so the displayed percentage detaches from actual cell voltage and the BIOS fires a protective shutdown early. Run two full discharge-to-hibernate cycles followed by uninterrupted charges to 100%. By the third cycle, the IC re-maps against the new cell's curve and the premature shutdowns stop.
The system info screen shows the wrong Wh rating for this battery — the number doesn't match 65.12Wh.
The Wh figure displayed in Windows or the BIOS is read from the battery's EEPROM, which may hold the rated value from the previous cell or a default placeholder until the fuel gauge IC recalibrates. The physical cell in this pack is rated at 65.12Wh. Complete one full discharge-to-hibernate cycle followed by a full uninterrupted charge, then recheck the system info panel — the reported Wh value should update to reflect the actual cell once the IC has completed its first calibration pass.
