Exact replacement for Audioline cordless phones

The Estry 3.6V 600mAh Ni-MH battery matches the original specifications for Audioline models CLA 103, CLA 120, CLT 3300, CLT 3600, CLT 4400, CLT 4600, CLT 5200 and CLT 6400. It also fits CLT 630, CLT 460 and CDL 960G handsets. The pack delivers 2.16Wh and carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications.

Chemistry and voltage set the practical limits

Nickel-metal-hydride chemistry requires a full charge cycle before first use and performs best when the handset remains on its charging cradle between calls. The 3.6V nominal voltage and 600mAh capacity are fixed by the phone's charging circuit; a higher-capacity cell will not increase talk time because the base station terminates charge at the same voltage threshold.

Simple two-wire connector fits the battery

The pack measures 42.6 x 29.95 x 14.54mm and weighs 87.2g, matching the original footprint. Installation fails most often when the polarity of the connector is reversed or when the handset's battery contacts are oxidised; cleaning the contacts with isopropyl alcohol before fitting the new pack restores reliable charging.
