What this battery replaces

Check before ordering

Verify that your handset is the BT Elements 1K model and that the existing battery label shows either 043048 or CS-BTK100CL. Confirm the connector orientation and cable length match the original pack. This unit is not compatible with other BT series phones or third-party handsets.

Performance over time

Capacity remains stable across repeated charge cycles without the memory effect seen in older nickel-based cells. Self-discharge is low so the handset stays ready after days on standby.
