Replacement for Kindle Oasis 2016

The KingSener 223337 is a new lithium-ion battery built to replace the original cell in the Amazon Kindle Oasis released in 2016. It delivers a 3.71 V nominal voltage and a 245 mAh capacity, matching the design specification so the e-reader regains its intended runtime. The pack uses the part number 58-000117 and is sized to fit the existing compartment without modification.

Thermals and power draw

Li-ion chemistry keeps self-discharge low and maintains a stable voltage curve during normal reading sessions, so the device runs cool and the battery does not heat up under typical load. There are no moving parts, so operation is completely silent. The supplier advises an initial conditioning routine of two to three full charge and discharge cycles at low current to reach rated capacity.

Upgrade context

This unit is a direct like-for-like swap for a depleted original battery; it does not increase capacity beyond the factory 245 mAh figure. The jump is worth it when the Oasis no longer holds a charge through a normal reading week or when the original cell shows swelling. Buyers who need a higher-capacity pack or a different voltage should look elsewhere, as this model replicates the stock specification exactly.

Questions about this item

How do I install the KingSener 223337 battery in my Kindle Oasis (2016) and what step is often missed?

Match the connector orientation exactly to the original 58-000117 battery before securing it; the polarity key is easy to reverse if you rush.

What maintenance will this 245mAh Li-ion cell need over time?

If stored, charge above 80% once a month; avoid constant adapter connection and hot or humid conditions to preserve capacity.

What limit appears first during sustained use of this 3.71V battery?

The 245mAh capacity dictates runtime; continuous draw depletes the small cell quickly, so expect shorter sessions than larger packs.
