Replacement battery for Galaxy S II

This Cameron Sino battery replaces the Samsung EB-L1A2GB and EB-L1A2GBA cells used in the Galaxy S II, SGH-I777 and AT&T Attain models. It is a direct-fit lithium-ion unit rated at 1.65 Ah and 3.7 V, supplied new and ready to install. The black casing matches the original equipment colour.

Single-cell Li-ion chemistry limits

As a single lithium-ion pouch, the pack delivers 6.11 Wh from a nominal 3.7 V platform. Capacity is fixed at 1650 mAh and cannot be expanded or combined with other cells. Users needing longer runtime between charges must carry a spare battery or use an external power bank instead.

Upgrades worn-out original cells

The unit restores original run-time for phones whose factory batteries no longer hold a useful charge after repeated cycles. It is not suited for devices that require a higher-capacity pack or a different form factor, and it does not add fast-charging circuitry absent from the handset.

Questions about this item

Is this the only capacity available for the Galaxy S II?

This model supplies 1.65 Ah (1650 mAh) at 3.7 V, which matches the original EB-L1A2GB specification for the Galaxy S II and Attain SGH-I777.

What does the 1.65 Ah rating deliver in daily use?

The 1.65 Ah cell stores 6.11 Wh, giving typical single-day runtime on a Galaxy S II under normal mixed use before recharge is needed.

Does the battery use a standard connector for the SGH-I777?

Yes, it fits the OEM EB-L1A2GB interface directly, so the handset recognises the cell and charges to the full 3.7 V / 1.65 Ah rating.
