Cameron & Co DS-CS-PRT100SL e-book accessory battery 700mAh 3.7V black

Replacement battery for Sony PRS-T series

The Cameron & Co DS-CS-PRT100SL is a lithium-polymer battery built for the Sony PRS-T1, PRS-T2, PRS-T3, PRS-T3E and PRS-T3S e-readers. It replaces the original 1-853-104-11 and LIS1476 cells with a 100% OEM-compatible unit. Readers who need a fresh power source for daily commuting or long trips will find it a direct fit. The black finish matches the original aesthetic.

Fits inside the original battery compartment

No tools beyond a small screwdriver are required to swap the old cell for this 66.85 x 43.80 x 3.00 mm pack. The connector aligns with the existing socket so the e-reader recognises the battery immediately. Installing it restores the device to portable use without relying on a mains adapter. Builders who need a second battery for a different model should look elsewhere.

700 mAh at 3.7 V for typical reading sessions

The 2.59 Wh capacity delivers enough energy for weeks of intermittent reading on a single charge. Heavy users who keep the front light at maximum brightness will see the runtime shorten accordingly. The lithium-polymer chemistry holds charge well during storage between books. Readers who want significantly longer endurance between charges cannot achieve it with this capacity.
