Replacement battery for Galaxy A11

This KingSener HQ-70N unit is a direct replacement battery for the Samsung Galaxy A11 (A115 2020). It uses Li-ion cells rated at 3.82V and 4000mAh to restore the original runtime. The pack is new and built to match the factory dimensions exactly. No adapters or modifications are required for installation.

Who this suits and who it does not

It suits owners of the Galaxy A11 (A115 2020) whose original battery no longer holds charge and who want a like-for-like swap. It is not for users of other Samsung models or different A11 variants where the connector or case outline differs. Buyers who need a higher capacity than 4000mAh will not find it here.

Deciding specification

The critical figure is the 3.82V / 4000mAh rating combined with the HQ-70N part number. Confirm that your original battery carries the same model code and voltage before ordering. A mismatch in either value means the pack will not fit or function correctly.

Questions about this item

How often should the 4000mAh Li-ion cell be cycled to maintain capacity?

Fully charge and discharge the battery from low current two or three times when new, then repeat a full cycle at least once per month if the phone is stored unused.

What is the first limit reached during continuous heavy use?

The 3.82V nominal voltage drops as the 4000mAh capacity is depleted, ending the usable runtime before thermal limits appear.

Does the replacement battery run hotter than the original during all-day use?

High-quality cells and matching PCB keep heat similar to the factory pack; avoid hot environments and long-term charger connection to prevent excess warmth.
