Direct replacement for Galaxy S III variants

This Estry battery is a direct replacement for the Samsung Galaxy S III and its regional variants including GT-I9300, SGH-I747, SGH-T999, SC-03E and SCH-J021. It matches the original EB585158LP, EB-L1G6LLU and GH43-03699A part numbers with a lithium cell rated at 3.8V and 2100mAh capacity. The pack carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications for safety compliance.

Verify model number and part code before ordering

Confirm the device model printed under the battery cover matches one of the listed compatible models such as S III, S3 Alpha or Progre 4G LTE. Cross-reference the existing battery part number against EB585158LP, EB-L1G6LLZ, EB-L1G6LVA or EB-L1G6LLUC to ensure correct fit. The cell measures 63.0 x 50.4 x 5.4mm and weighs 61.6g so it sits flush in the original compartment.

Fits existing chassis without modification

The battery slots into the standard S III battery bay and connects to the original terminals, requiring no adapter or soldering. Built-in protection guards against overcharge, over-discharge, over-voltage and short circuits to protect the phone circuitry. At 7.98Wh it restores factory runtime for daily use, freeing the user from carrying a power bank for routine tasks. Buyers needing higher capacity or a different form factor should look elsewhere.
