Up to 20% off
New arrival
From $75.99 USD $93.99
Shipping calculated at checkout.
Fits ECS Elitegroup Alphatop G320, G720, G799 notebooks; replaces OEM part numbers LIP8020, LIP8082, EM-G320L1, EM-G320L2, ES1-2200, ES1-4400.
14.8V lithium-ion, 4400mAh capacity delivers 65.12Wh—sufficient for 4–6 hours typical office use on this chassis.
Connector seats flush into the battery bay with a single locking tab; orientation is fixed by the keyed slot on the pack housing.
We bench-tested this cell against an aged G320 pack; the BMS accepted charge current cleanly and held 14.8V under simulated CPU load without sag.
After installation, run one full discharge to hibernation-cutoff then charge uninterrupted to 100%—this resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap.

I'm writing this review to express my deep gratitude and appreciation for the quality of services provided to me by the BatteryWeb service team. I visited BatteryWeb to purchase a replacement battery for my Remington R9 razor. The staff was very responsive and I was really impressed with their willingness to help me and make the purchasing process as quick as possible. In particular I greatly appreciate the work of staff member Shane who was friendly and helpful.
In conclusion, I believe that BatteryWeb has excellent service staff who make their customers feel honored and valued.
I wish you all the best.
Sincerely,
Michael

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.

ECS Elitegroup Alphatop G320 — 14.8V Li-ion Replacement Battery (LIP8020)

This 14.8V, 4400mAh (65.12Wh) Li-ion battery replaces the original cell in the ECS Elitegroup Alphatop G320, G720, and G799 series notebooks. It also fits the Green 320 platform sharing the same connector and voltage rail. OEM part numbers covered include LIP8020, LIP8082, EM-G320L1, EM-G320L2, ES1-2200, and ES1-4400.

  • G320 / G720 / G799 platform compatibility: These three Alphatop models share the same 14.8V four-cell configuration, battery bay connector, and BMS handshake protocol — a single cell SKU covers the group without modification.
  • Bench tested on actual hardware: We ran this cell through full charge and load cycles. The BMS communicated correctly with the host system, accepted a full charge without early cutoff, and held voltage under sustained CPU and display load without triggering a protective shutdown.
  • Post-install calibration on the Alphatop G320: After fitting this cell, run one full discharge to the hibernate cutoff point, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning the Alphatop firmware displays after every cell swap.

Alphatop G320 shutting down at 20–30% charge shown

This is a voltage cliff issue, not a firmware fault. Under combined CPU and display load, the cell voltage drops faster than the fuel gauge IC can track — the system sees voltage fall below the safe floor and cuts power before the displayed percentage reaches zero. The old battery's discharge curve was mapped into the BIOS; a new cell with fresh capacity doesn't match that stored curve yet. Run two full calibration cycles — full discharge to hibernate, full uninterrupted charge — and the BIOS learn cycle will remap against the new cell's actual voltage curve.

BIOS reporting wrong Wh rating after cell swap

The Wh figure shown in BIOS or system info reads from EEPROM data stored on the battery's BMS chip, not from live measurement. A replacement cell's EEPROM is programmed to its rated chemistry specification, which can differ slightly from the previous cell's stored value. This is not a fault — the cell capacity is correct at 65.12Wh. If the BIOS value still looks wrong after one full charge cycle, pull the AC adapter, discharge fully to hibernate, then recharge to 100% to trigger a fresh EEPROM read.

Frequently Asked Questions

My Alphatop G320 shows the new battery as "0%" or "unknown" straight after I fitted it — is the cell dead?

No. The fuel gauge IC on the Alphatop's motherboard loses its reference point when the original cell is removed. It has no data to read until it runs at least one full cycle against the new cell. Plug in the AC adapter, let it charge uninterrupted to 100%, then discharge fully to hibernate cutoff. After that first complete cycle the gauge will register correctly.

The OS fuel gauge is jumping around wildly — showing 60%, then 85%, then 45% within minutes on my G320.

The fuel gauge IC calibrates its capacity estimate against the cell's actual discharge curve. A brand-new cell has a curve the IC has never seen before, so readings are erratic for the first two to three cycles. This settles on its own. Run two full discharge-to-hibernate then full uninterrupted charge cycles — after cycle three the gauge should track within a few percent of actual remaining capacity.

My G320 stopped charging at 80% and won't go higher — I've tried two different chargers.

This is almost always a BIOS-controlled charge limit, not a battery fault. Some Alphatop firmware builds ship with a battery health mode that caps charge at 80% to reduce cell wear — it activates silently and persists across reboots. Check the ECS BIOS setup utility under the Power or Battery section and disable the charge threshold setting. Once cleared, the cell will charge to 100%.
