Dr. Battery 10.8V 4400mAh Replacement

This new lithium-ion battery replaces original Acer TimelineX packs in the 4820T 4820TG 5820T and 5820TG families. It restores mobile runtime for owners of those specific models who need a direct 10.8V 48Wh substitute.

Simple swap with built-in protection

The pack fits the existing battery bay without tools and includes short-circuit overheat and overload safeguards. The main risk is ordering the wrong part — the 3820 series is explicitly not supported so verify your exact model and original battery number before purchase.

Voltage and capacity match decides fit

Only a 10.8V 4400mAh rating guarantees correct charging and runtime for the listed TimelineX machines. A different voltage or capacity will not work even if the physical shape appears similar.
