Purpose and compatibility

This Cameron & Co DS-CS-P28115CL lithium-ion battery replaces the original pack in a wide range of DECT 6.0 cordless handsets from brands such as GE, Philips, Thomson, Grundig, Alcatel, Swissvoice and BT. It delivers 3.7 V and .5 Ah of capacity for models including the 28106, 28115 and 28118 series as well as the Versatis Slim 300 and Iron handsets.

Thermals noise and power

As a low-voltage Li-ion cell rated at 1.85 Wh, the battery generates negligible heat and makes no audible noise during normal standby or talk time. Power draw follows the handset’s own transmitter duty cycle, so typical use mirrors the original pack’s runtime without extra thermal load on the phone chassis.

Build and daily use

The black rectangular cell measures 43.00 x 28.00 x 4.00 mm and fits the original battery compartment without modification. Standard polarity tabs align with the handset’s connector, allowing a straight swap that restores talk and standby time for compatible devices such as the BT Granite, Philips ID 555 series and Grundig Scenos models.

Questions about this item

How do I install the DS-CS-P28115CL battery in my DECT 6.0 UltraSlim handset, and what step is often missed?

Open the battery compartment, disconnect the old pack, connect the new 3.7 V 500 mAh Li-ion battery observing the polarity markings, then secure the cover; the step often missed is ensuring the connector clicks fully into place before closing the cover.

What maintenance or replacement will the DS-CS-P28115CL need over time?

Li-ion cells degrade with charge cycles; expect reduced talk time after roughly 300–500 full cycles, at which point the battery should be replaced with another 3.7 V 0.5 Ah pack of the same 43.00 x 28.00 x 4.00 mm form factor.

What limit appears first during a long call on the DS-CS-P28115CL?

The 1.85 Wh capacity sets the practical limit; continuous use will drain the 500 mAh cell in a few hours, so talk time ends before any thermal or voltage protection triggers.
