Dr. Battery 11.1V 4400mAh Replacement

This 11.1V 4400mAh lithium-ion battery replaces original Acer AS07B31, AS07B41, AS07B51, AS07B61, AS07B71, AS07BX1 and AS07BX2 packs. It fits a long list of Gateway MC, MD and NV series notebooks as well as Acer Aspire 5220, 5315, 5520, 5720, 5730, 6930 and 7720 models. Buyers who need a different voltage or a higher capacity pack cannot use this unit.

Sustained discharge with protection circuits

The 49Wh cell delivers a steady 11.1V output during extended work sessions and includes short-circuit, overheat and overload safeguards. Internal protection circuitry regulates current flow to keep temperatures stable under continuous load. The pack is not compatible with 10.8V-only systems or Aspire 8930 series laptops.

Simple bay swap with model verification

Installation requires sliding the pack into the laptop battery bay until the latch clicks, a process that takes less than a minute. The most common issue is ordering the wrong voltage; this battery only works with 10.8V and 11.1V versions, so confirming the original part number such as AS07B31 or BT.00603.033 before purchase avoids returns.

Questions about this item

Does the 11.1 V lithium-ion pack run hot or draw extra power during all-day use?

The battery operates at its rated 11.1 V with built-in overheat and overload protection, so it stays within normal thermal limits during extended sessions.

What must I already own for this DRPROAC203P-02 to work in my laptop?

You need a compatible Gateway or Acer notebook such as the Aspire 5220, 5720, 5730, 5520, 6930, 7720 or 5315, or a Gateway MD2614u / MD2601u series model.

Will this 49 Wh replacement work alongside the original 10.8 V battery I kept as a spare?

The pack is compatible with both 10.8 V and 11.1 V systems, so it can replace the original and the older spare can remain as a backup.
