Cameron & Co DS-CS-STP446TW Li-ion battery 3.7V 800mAh black

Ready Power for Marine Radios

This Cameron & Co lithium-ion cell replaces the original pack in Stabo 20640, freecomm 600 Set, PMR 446 and Topcom Twintalker 7100 handsets. It matches the FT553444P-2S part number and delivers 3.7V with an 800mAh rating for 2.96Wh of capacity. The slim 46.35 x 31.94 x 6.31 mm black housing slides straight into the radio's battery bay without modification. Boaters and field teams who need a direct-fit spare for these specific models will find it ready to install.

Steady Output Through a Shift

The 0.8Ah lithium chemistry maintains a consistent voltage curve during extended transmit cycles rather than sagging after a few bursts. That behaviour keeps the radio at full power for longer conversations on channel 446 or during a day on the water. Users who regularly drain a pack to empty before recharging will notice fewer early low-battery warnings compared with aged original cells. The pack is not suited for radios that require a higher capacity or a different voltage platform.

Compact Shell, Simple Swap

The 6.31 mm thickness lets the battery sit flush against the radio body so belt clips and waterproof cases still close properly. Gold-plated contacts resist corrosion from salt spray and humidity common in marine environments. A single black unit ships in sealed packaging, so there are no extra cables, chargers or adapters to manage. Builders needing a multi-cell pack or a different connector layout should look elsewhere.
