Replacement battery for Vivo Y55 series

This Cameron & Co DS-CS-BKY550SL battery fits Vivo Y55, Y55A and Y55L models. It replaces the original B-B1 and BBK B-B1 packs with a 2.7 Ah lithium-polymer cell. The black unit measures 83.10 x 61.20 x 3.20 mm and supplies 3.85 V for 10.40 Wh of energy. It arrives new and fully compatible with the listed handsets.

Owners of compatible Vivo phones needing a fresh

The pack suits anyone whose Y55, Y55A or Y55L no longer holds a charge and who wants a direct OEM-style replacement. Buyers with different Vivo models or other brands should look elsewhere because the connector and dimensions are specific to the Y55 family. It is not for users who need a higher-capacity pack or a power-bank solution.

Check your exact model number and battery code

Before ordering, confirm the phone shows Y55, Y55A or Y55L in its settings or on the label. Verify the old battery carries part number B-B1 or BBK B-B1 so the connector matches. Ensure the handset back cover can be removed to access the cell; some variants use adhesive that requires careful prying. No tools are included.
