Replacement Battery for Acer Aspire Laptops

This 6-cell lithium-ion battery delivers 10.8V and 4400mAh capacity for compatible Acer Aspire models. It suits owners of listed Aspire 4250, 4551, 4739, 5250, 5251, 5253, 5336, 5349, 5551, 5552, 5733, 5733Z, 5736Z, 5742, 5742Z, 5749, 5749Z, 5750, 5755, 7551, 7560, 7741G, 7750, AS5336, E1-431 and E1-531 series laptops needing a fresh power source. Built-in protection circuits guard against short circuit, overheat and overload during use.

Upgrade from Worn or Failed Original Cells

The pack replaces OEM part numbers BT.00607.130, BT.0060G.001, BT00603111, BT00603124, BT00606008, BT00607125 and BT00607126 when the original no longer holds charge. A smart control chip supports quicker charging, lower power consumption and longer discharge time compared with degraded cells. The swap is worth it when runtime has dropped noticeably or the laptop shuts down unexpectedly on battery power.

Check Model Number and Voltage Before Ordering

Confirm the laptop model appears in the compatibility list and that the original battery shows 10.8V output. Compare the physical shape and connector orientation with your existing pack to ensure a proper fit. This unit is not for users whose laptops require a different voltage, cell count or form factor.
