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 Aspire E5-575G-53VG — 11.1V Li-ion Replacement Battery (AS16B5J)
This is a 11.1V, 5200mAh (57.72Wh) Li-ion battery built to replace the original cell in the Acer Aspire E5-575G-53VG and a broad range of Aspire E5, F5, and related 15.6-inch notebook models. It cross-references OEM part numbers AS16B5J, AS16B8J, and KT.0060G.001. The connector, pin count, and BMS communication protocol match the original specification.
- Aspire E5/F5 platform compatibility: These models share a common board architecture, battery connector, and BMS handshake protocol across the E5-575, E5-575G, and F5-573G lines. The same voltage rail and physical form factor let one cell cover all of them without modification.
- Bench tested on actual hardware: We ran this cell on an E5-575G board and confirmed the BMS initialised correctly, charge current stepped down at the expected voltage threshold, and the system did not flag a protection-circuit fault during the first full cycle.
- First-cycle calibration after swap: After installing, discharge fully until the laptop hibernates, then charge uninterrupted to 100% without interruption. This triggers the BIOS battery learn cycle, clears the inaccurate health warning that appears after every cell swap, and lets the fuel gauge IC baseline against the new cell chemistry.
BIOS reporting battery health as poor immediately after replacement
Acer's BIOS stores charge history and health data from the previous cell in firmware. When a new cell goes in, that cached data does not automatically reset — so the system reads the old degraded profile and flags poor health regardless of actual cell condition. Running one complete discharge-to-hibernate followed by an uninterrupted charge to 100% forces the BIOS learn cycle to rewrite that profile. After two or three full cycles, the health indicator should clear and report normally.
Laptop shuts down abruptly at 20–30% charge shown on screen
This happens when the fuel gauge IC has not yet calibrated against the new cell's actual voltage curve. At high CPU and display load, the cell's terminal voltage drops faster than the uncalibrated gauge predicts, and the system hits undervoltage cutoff while the OS still shows 20–30%. It is not a fault with the replacement cell. Run two full discharge-to-hibernate cycles back-to-back, letting each complete without plugging in early, then charge to 100%. By the third cycle the gauge typically tracks the real voltage curve and the premature shutdowns stop.

Frequently Asked Questions
Why does Windows show the Acer battery as "0% available (plugged in, not charging)" right after I installed it?
The fuel gauge IC on the E5-575G board needs the old EEPROM data cleared before it will accept a new cell. Disconnect the AC adapter, let the laptop run on battery until it hibernates, then plug back in and charge without interruption to 100%. That full discharge-charge sequence resets the fuel gauge baseline and Windows will resume reporting a normal percentage.
My Acer Aspire shows 57Wh in the BIOS but Windows reports a different Wh figure — is the battery faulty?
No. The EEPROM on a replacement cell stores the rated design capacity from the manufacturer, while Windows calculates its own "full charge capacity" figure based on what the fuel gauge IC measures during actual charging. These two numbers rarely match exactly on the first cycle. After two or three full charge-discharge cycles the Windows-reported value stabilises and typically lands within a few percent of the rated 57.72Wh.
The new battery stopped charging at 80% and won't go higher — what's blocking it?
Acer's BIOS on several E5 and F5 models includes a charge-limit setting that caps charging at 80% to reduce cell wear during AC-connected use. Check Acer Care Center or the BIOS power management settings — look for a "Battery Health Charging" or "Maximum Battery Charge" option. Set it to 100% and the charge ceiling lifts immediately on the next charge cycle.
