Estry Standard Battery 2.4V 600mAh Ni-MH for Audioline SLIM DECT 500 502 580 582

Replacement Battery for Audioline SLIM DECT Phones

This 2.4V 600mAh Ni-MH pack replaces the original battery in Audioline SLIM DECT 500, 502, 580 and 582 handsets. It matches the factory specifications for voltage and capacity so the phone charges and reports remaining power correctly. The 1.44Wh cell fits the existing compartment without modification.

Thermal Behaviour and Power Draw

Nickel-metal-hydride chemistry runs cool during normal standby and talk time, producing no noticeable heat in the handset. Self-discharge is low, so a fully charged pack holds usable energy for weeks when the phone sits on its base. The protection circuit prevents over-charge, over-discharge and short-circuit conditions without adding audible noise.

Sustained Load Performance

During long conversations the cell delivers a steady current until the handset signals low battery, avoiding the sudden voltage drops seen in aged packs. Repeated daily charge cycles are supported by the ISO9001, RoHS, CE, UN38.3 and MSDS certifications that confirm consistent manufacturing quality. Capacity remains stable over hundreds of cycles when the phone is returned to its charger after each use.
