11.1V 49Wh replacement battery for Acer TravelMate

The Dr. Battery BATBL50L6 is a new lithium-ion pack rated at 11.1V and 49Wh. It fits a wide range of Acer TravelMate 2490, 4200 and 4230 series laptops plus several Aspire, Extensa and eMachines models. The battery restores mobile runtime for machines whose original cells have degraded.

Upgrading from a worn original pack

When the factory battery no longer holds a useful charge this unit replaces it directly with the same voltage and capacity. The jump is worth it if the laptop otherwise meets your needs but is tethered to an outlet. It is not for buyers who need higher capacity than 49Wh or a different voltage.

Fits existing battery bay without extra parts

The pack slots into the standard battery compartment using the original latch and connector. No adapters, cables or firmware updates are required. It frees you from carrying a bulky power brick for short trips. Builders who need a second battery for hot-swap configurations cannot use this single pack alone.
