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.

Acer TravelMate 5310-400508Mi — 14.8V Li-ion Replacement Battery (GRAPE34)
This is a 14.8V, 4400mAh (65.12Wh) Li-ion replacement battery for the Acer TravelMate 5310-400508Mi and a wide range of TravelMate 5520G, 5720, and 7520G laptops. It replaces failed or capacity-depleted original cells using OEM part numbers including GRAPE34, LC.BTP00.006, and BT.00807.013. Voltage, connector pinout, and BMS communication all match the original specification.
- TravelMate 5310 / 5520G / 5720 / 7520G compatibility: These models share the same 14.8V four-cell battery architecture, identical connector housing, and the same BMS handshake protocol — which is why one replacement cell covers the full platform range across those series.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on TravelMate hardware. The BMS negotiated correctly with the BIOS, reported state-of-charge without error flags, and held voltage across the full discharge curve without unexpected cutoff.
- First-install calibration on TravelMate laptops: After fitting this cell, run one full discharge to hibernate 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 on this platform.
Why the TravelMate BIOS flags a new battery as poor health immediately after swap
The TravelMate BIOS reads health data from the battery's EEPROM, not from live cell voltage. When a new cell arrives, its EEPROM counters start at zero and its rated Wh figure may differ slightly from what the BIOS expects — triggering a false poor-health flag. This is a data mismatch, not a faulty battery. Running one full discharge-to-hibernate followed by a complete uninterrupted charge gives the fuel gauge IC enough data to recalibrate and clears the BIOS warning on most TravelMate units.
TravelMate shutting down at 20–30% charge shown on the gauge
When a battery's cells age, they hit a voltage cliff under combined CPU and display load — the cell voltage drops below the BMS cutoff threshold before the fuel gauge reaches zero. The result looks like an early shutdown, but the gauge reading is wrong, not the hardware. After installing this replacement, the fuel gauge IC needs two to three full charge-discharge cycles to map the new cell's actual voltage curve. Until those calibration cycles complete, the percentage shown may be inaccurate — do not judge the cell by the first cycle reading.

Frequently Asked Questions
The Acer TravelMate BIOS shows the new battery as 0% or "unknown" straight after fitting — is the cell dead?
The BIOS is reading stale EEPROM data from the old battery session, not the live state of the new cell. Plug in the AC adapter and leave the laptop charging for a full uninterrupted cycle before drawing any conclusions. Once the fuel gauge IC has a complete charge cycle to work from, the BIOS health readout resets. If the display still shows 0% after one full charge, check that the battery connector is fully seated — a partially engaged pin will block BMS communication entirely.
The system info panel shows a Wh rating that does not match the 65.12Wh listed on the product page — which figure is correct?
The figure the OS reports comes from the EEPROM embedded in the battery pack, which stores the rated design capacity from the cell manufacturer. Small differences between that EEPROM value and the product-listed 65.12Wh are normal — they reflect rounding and the difference between rated and measured cell capacity. Neither figure is wrong. The number that matters is actual charge held across a full cycle, which the fuel gauge IC only calculates accurately after two or three calibration cycles.
Why does the TravelMate charge stop at 80% and refuse to go higher after fitting the replacement cell?
Some TravelMate BIOS versions include a charge-limit setting — sometimes labelled Battery Health Mode or similar — that caps charging at 80% to reduce long-term cell stress. This is a firmware control, not a fault with the replacement cell. Open the BIOS setup at boot, locate the battery or power management section, and disable the charge limit or set the threshold to 100%.
