Direct replacement for Aastra DECT handsets

The Cameron Sino DS-CS-ADT690CL is a lithium-ion battery built to replace the original packs used in Aastra DH4-BAAA/2B, DT690 and DT692 cordless phones. It matches the OEM part numbers 660190/1A, 660190/R2B and 660216/1B1 for a direct fit. The 3.7 V, 930 mAh cell delivers 3.44 Wh of capacity in a black housing measuring 72.80 x 43.78 x 9.20 mm.

Low self-discharge chemistry for standby readiness

Lithium-ion construction keeps self-discharge minimal, so the handset holds charge during long periods on the cradle or in storage. No memory effect means the pack can be topped up at any state of charge without reducing usable capacity. Normal office use produces no audible noise and negligible heat from the battery itself.

Steady output through a full talk-time cycle

Under continuous call load the cell maintains a stable voltage curve, avoiding the sharp drop-off seen in aged nickel-based packs. Capacity remains consistent across repeated charge cycles, supporting the handset's rated talk and standby times. The pack is not suited for devices requiring higher voltage or different form factors.

Questions about this item

How do I install the DS-CS-ADT690CL battery in my Aastra DT690 handset, and what step is often missed?

Power off the handset, remove the battery cover, disconnect the old pack, connect the new 3.7V 930mAh Li-ion battery ensuring the connector clicks fully into place, refit the cover, then charge for several hours before first use.

What maintenance or replacement will this 3.44Wh Li-ion battery need over time?

The battery will gradually lose capacity; expect to replace it when talk time drops noticeably or the handset no longer holds a charge through a normal shift, typically after several hundred charge cycles.

What limit appears first during sustained heavy use of this 0.93Ah pack?

Under continuous calls the 930mAh capacity depletes first, requiring a recharge before the handset can be used again.
