Ready replacement for Huawei phones

This Cameron & Co DS-CS-HUT220SL battery fits the Honor Note 10, Mate 20 X and related models such as RVL-AL09 and EVR-L29. It replaces the original HB3973A5ECW pack with a 4.9 Ah lithium-polymer cell rated at 3.85 V and 18.87 Wh. The unit is supplied new and ready for installation.

Direct swap restores original runtime

No cables, tools or software are bundled; the battery itself is the only component. Fitting it restores the factory capacity of 4900 mAh so the phone can again reach its rated screen-on time between charges. The black polymer casing matches the OEM colour and fits the existing battery compartment without modification.

Slim profile fits sealed chassis

At 102.65 x 72.24 x 3.74 mm the pack slides into the tight internal space of the listed Huawei handsets. The thin 3.74 mm depth means no pressure on the back cover or display assembly after reassembly. Li-polymer chemistry keeps weight low while delivering the specified 18.87 Wh. Buyers needing a higher-capacity pack or a different voltage will not be served by this model.

Questions about this item

Will the Li-Polymer cell need replacement after a certain number of charge cycles?

The 4.9 Ah Li-Polymer cell is a consumable component; capacity typically fades after several hundred full cycles, so plan to replace the pack when run-time drops below your needs.

What stops the 4900 mAh pack from delivering full current during a long gaming session?

Internal resistance and the phone's thermal throttle limit sustained output; the 3.85 V nominal voltage will sag under heavy load, triggering the device to reduce performance.

Does the 3.74 mm thick battery get hot or draw extra power when the phone runs all day?

Normal operation warms the cell slightly, but the Li-Polymer chemistry and slim 3.74 mm profile are designed to dissipate heat without active cooling or noticeable noise.
