Replacement battery for Acer Timeline series

This lithium-ion battery replaces the original Acer AS09D34, AS09D56 and AS09D70 packs used in Aspire Timeline 3810T, 4810T and 5810T models. It is built for owners who need a new power source after the factory cell has lost capacity.

Sustained discharge at 4.4 Ah

The 4.4 Ah rating delivers a steady current over long work sessions rather than a brief peak. The cell chemistry maintains voltage through extended typing, browsing or video playback without the sharp drop seen in aged packs.

Low heat and silent operation

Normal office loads keep the pack near ambient temperature and it produces no audible noise. Power draw follows the laptop's own management, so the system regulates charge rate and thermal limits without extra fan activity.
