Cameron & Co DS-CS-LVT550NB replacement battery

This Cameron & Co DS-CS-LVT550NB is a new lithium-polymer battery built for select Lenovo ThinkPad models. It delivers 11.4V and 3.9Ah capacity in a black housing measuring 197.50 x 93.92 x 7.38 mm. The unit replaces original part numbers 00NY639, 45N1740, 45N1741, 45N1742, 45N1743 and SB10K12721.

Fits ThinkPad T550, T550s, T560, W550 and W550s.

This battery suits owners of the listed ThinkPad T550, T550s, T560, W550 and W550s machines who need a direct 11.4V replacement. Buyers with different ThinkPad series or non-Lenovo notebooks should look elsewhere because the connector and form factor only match the models named above.

Voltage and capacity must match 11.4V 3.9Ah

The single specification that decides fit is the 11.4V 3.9Ah rating paired with the exact part-number cross-reference. A battery with a different voltage or capacity will not operate correctly in the supported ThinkPad T550, T560 or W550 systems.
