Replacement battery for Xperia Z3

This Cameron & Co DS-CS-ERZ300SL is a new lithium-polymer cell built for the Sony Ericsson Xperia Z3 family including D6603, D6616, D6633, D6653, L55T, L55u, M55w and related Pegasus models. It arrives ready to install in black.

Capacity and daily headroom

Rated at 3.1 Ah (3100 mAh) and 11.78 Wh at 3.8 V, the pack matches the original LIS1558ERPC specification. It powers normal mixed use through a full day, while heavy GPS navigation or continuous video streaming will drain it faster.

Physical fit and connection limits

The cell measures 79.05 x 60.26 x 4.26 mm and uses the stock connector, so it seats directly in the handset without adapters. Buyers needing higher capacity or a different form factor will not be served by this single-unit replacement.
