Cameron & Co DS-CS-AUT300NB laptop battery 6.75 Ah Li-Polymer Black

Cameron & Co DS-CS-AUT300NB Li-Polymer Battery

This Cameron & Co DS-CS-AUT300NB is a 6.75 Ah lithium-polymer replacement battery built for Asus Transformer Book T300, T300L and T300LA models. It suits owners of those devices who need a fresh 7.4 V power source with 49.95 Wh capacity. The black pack measures 192.53 x 165.10 x 5.23 mm and replaces part numbers 0B200-00570000 and C22N1307. Buyers whose laptops use a different connector or voltage should look elsewhere.

Practical limits of the 7.4 V Li-Polymer interface

The pack delivers 6750 mAh at a fixed 7.4 V, so runtime scales directly with the notebook’s power draw and cannot exceed the cell chemistry’s inherent discharge curve. Capacity will diminish over charge cycles and the thin 5.23 mm profile leaves no room for additional thermal buffering. Systems that expect a different voltage or a smart-battery data protocol may not report charge levels correctly.

Installation notes and common pitfalls

The battery slots into the Transformer Book’s internal bay without tools, but the fragile flex cable and adhesive strips require careful alignment to avoid pinching. First-time installers often forget to disconnect the old pack before prying it loose, risking a short on the mainboard. Applying even pressure across the 192.53 mm length prevents the polymer pouch from creasing, which would permanently reduce the 6.75 Ah capacity.
