Short summary and practical steps relevant to 's TravelMate 4011WLCI and 's suggestion to contact Acer support.

Identify the battery first. Laptops use either a coin cell (round, held in a clip) or a small rechargeable battery pack (flat/rectangular or cylindrical cells with a two‑wire connector). Coin cells are typically 3.0 V types (CR2032, CR2025, CR2016); some older laptops use a rechargeable 3.6 V NiMH pack. The correct replacement must match the battery chemistry and voltage and have a compatible connector or holder. A visible part number on the battery harness or a marking on the mainboard (FRU/PN) is the most reliable identifier.

Safe replacement workflow. Remove AC and the main battery, discharge residual power, and ground against static. Open the access panel per the service manual, note the battery shape and connector, record any markings, and measure the old battery voltage with a multimeter if available. If the cell is in a holder, replace with an identical coin cell paying attention to polarity. If the unit uses a wired pack or a soldered cell, obtain the exact replacement pack or have a qualified technician replace it—never substitute a battery with a different nominal voltage.

Where to source the correct part. Manufacturer parts lists/service manuals and motherboard FRU numbers provide exact part numbers; parts sellers and local electronics shops can match a battery from a clear photo of the battery/connector plus the laptop model and any board stickers. Prioritize an identical voltage and connector; brand matching is not required but quality matters. After replacement, verify BIOS time and settings and reconfigure any lost settings.

Cautions. Avoid guessing by size alone. Soldering on the motherboard risks damage. If uncertainty remains, the manufacturer or a repair shop is the safer route.

if the batteries are the same size and voltage, shouldn't be a problem
