Compatible replacement battery

The Cameron & Co DS-CS-KBM204SL is a lithium-polymer battery built for Kobo Aura HD and N204-KBO-B e-readers. It replaces the original SP305590 pack and restores the device to its factory power profile. Readers who need a fresh cell for daily reading sessions will find a direct-fit solution.

Thermals noise and power draw

The 3.7 V 1500 mAh cell stores 5.55 Wh and uses Li-Polymer chemistry that runs cool during normal page turns and wireless sync. No fan or moving parts are present, so operation stays silent. Power draw follows the e-reader's low-current design without extra heat.

Build quality and daily implications

The black pack measures 84.50 x 49.00 x 2.80 mm and slots into the existing battery cavity without modification. OEM-compatible connectors align with the stock header for a secure fit. The slim 2.80 mm thickness keeps the original device profile intact for comfortable one-handed reading.

Questions about this item

How do I install the DS-CS-KBM204SL battery in my Kobo Aura HD, and which step is often missed?

Remove the back cover, disconnect the old pack, connect the new 3.7V 1500mAh Li-Polymer unit, and reassemble; the step often missed is ensuring the connector clicks fully into the socket before closing the case.

What maintenance or replacement will the DS-CS-KBM204SL battery need later?

No routine maintenance is required; when runtime drops noticeably, replace the whole 1.5 Ah pack with another DS-CS-KBM204SL.

What limit appears first during sustained reading on the DS-CS-KBM204SL battery?

The 5.55 Wh capacity sets the runtime ceiling; after several hours of continuous use the voltage will fall and the e-reader will shut down until recharged.
