Replacement for Acer Aspire TimelineX series
This 6-cell lithium-ion battery replaces original Acer packs across the Aspire 4553, 4745, 4820, 5553, 5745, 5820, 7250, 7739 and 7745 families. It is built for owners who need a direct-fit, new-condition power source without modifying the chassis. The black housing matches the factory aesthetic and installs using the existing latch mechanism.
Thermals, noise and power draw in normal use
The 10.8 V, 4400 mAh (48 Wh) chemistry delivers steady voltage under typical office and browsing loads. An integrated smart control chip manages charge current, reduces self-discharge and activates short-circuit, overheat and overload safeguards. No moving parts means silent operation and no additional heat beyond the cells themselves.
Upgrades worn or failed original packs
Swapping out a depleted BT.00607.122, BT.00607.123, BT.00607.124, BT.00607.128, LC.BTP00.119, LC.BTP01.029 or AK.006BT.081 restores full runtime and reliable charging. The jump is worth it when the original battery no longer holds a useful charge or triggers capacity warnings. Not for buyers who need higher capacity than 4400 mAh or a different voltage.

Questions about this item
How do I install the 6-cell 10.8V pack in my Acer Aspire 5820TG, and what step is often missed?
Power off the laptop, remove the AC adapter, slide the release latch, insert the pack until it clicks, then charge fully before first use; the step often missed is the initial full charge cycle.
What replacement will this 4400mAh lithium-ion battery need over time?
The pack itself is the only replaceable part; swap it for a new 6-cell 10.8V unit when capacity falls below useful levels.
What limit appears first during sustained use of this 48Wh battery?
The 4400mAh capacity determines runtime; under continuous load the pack will deplete before any thermal or voltage threshold is reached.
