Replacement Battery for Alcatel DECT Phones

The Cameron & Co DS-CS-ALM300CL is a lithium-ion replacement cell built for Alcatel DECT handsets including the 300, 400, Reflexes and Octophon Open series. It restores talk time for home or office cordless phones that use the original ALCH-011664AC or 3BN66305AAAA part numbers. Buyers needing a battery for a different brand or a smartphone will not find a match here.

Steady Low-Power Operation

The 3.7 V, 800 mAh cell delivers 2.96 Wh of energy for long standby and talk sessions typical of DECT use. Lithium-ion chemistry keeps self-discharge low so the handset stays ready after days on the cradle. No active cooling or high-current draw is involved, so the battery runs silently and stays cool during normal charging cycles.

Direct Fit with OEM Dimensions

Measuring 51.23 x 37.90 x 11.28 mm, the pack slides into the handset battery compartment without adapters or filing. The black casing matches the original aesthetic and the connector alignment follows the factory layout for a secure click. Users who need a higher-capacity pack or a different voltage should look elsewhere.

Questions about this item

How do I fit the DS-CS-ALM300CL into my Alcatel 300 DECT handset, and which step do people often miss?

Open the battery cover, align the 51.23 x 37.90 x 11.28 mm pack with the contacts, press until it clicks, then close the cover — the step most often missed is ensuring the connector seats fully before snapping the cover shut.

What maintenance or replacement will this 3.7 V 800 mAh Li-ion pack need over time?

Keep the contacts clean and store the handset in a cool place; when talk time falls well below the original 2.96 Wh rating, swap in a fresh DS-CS-ALM300CL unit.

What limit appears first during a long call on this 0.8 Ah battery?

The 800 mAh capacity sets the talk-time ceiling; once the charge drops the handset will power down until recharged.
