Direct replacement for Portege and Tecra models

This GreenTech battery replaces the OEM PA5331U-1BRS pack in Portege A30-E, R30-A, X30L-G and Tecra A30-G and A40-E series laptops. It is a brand-new 4-cell lithium-ion unit tested for correct voltage and circuit protection. Buyers with other Dynabook chassis or different part numbers cannot use this pack.

42 Wh capacity for typical office workloads

The 15.4 V, 2700 mAh rating delivers 42 Wh, enough for a full day of document editing and web browsing on supported ultraportables. Heavier loads such as sustained video rendering or virtual machines will drain the pack faster and require mid-day recharging. Users needing longer unplugged runtime must choose a higher-capacity alternative.

Black 4-cell housing with CE.

The pack fits the internal battery bay without adapters and uses the original connector layout for a secure fit. Rigorous pre-ship testing confirms stable current and low self-discharge. The certified cells meet safety standards but the battery is not hot-swappable; the laptop must be powered down for installation.

Questions about this item

Will this 15.4V 42WHR battery fit alongside the existing power connector on my Portege A30-E?

Yes, it replaces OEM part numbers PA5331U-1BRS and PA5331U and is listed as compatible with the Portege A30-E series, so it uses the same connector and mounting points.

How can I confirm the battery is working correctly after installing it in my Tecra A40-G?

After installation the OS should detect a 15.4V 2700mAh 4-cell pack, show charging status, and report capacity near the rated 42WHR in the battery health section.

Does the package include only the battery or are screws and tools also supplied?

The box contains the GreenTech 4-cell lithium-ion battery unit only; any screws or tools needed for the swap must be sourced separately.
