Cameron & Co DS-CS-LVE590NB laptop battery 4.05 Ah

Cameron Sino DS-CS-LVE590NB 4.05 Ah Li-Polymer

This replacement battery fits Lenovo ThinkPad E14, E15, E480, E485 and E490 models. It uses Li-Polymer chemistry rated at 4.05 Ah and comes in black. The part replaces Lenovo numbers 01AV446, L17C3P51, L17M3P52 and L17M3P53. It is intended for owners of those specific ThinkPad laptops who need a new internal battery.

Sustained load behaviour

Li-Polymer cells maintain a steady voltage curve during long work sessions, so run-time stays consistent rather than dropping sharply after a short burst. The 4.05 Ah capacity supports typical office workloads across a full day without the sharp fade seen in aged original packs. Heat build-up stays moderate because the chemistry handles continuous discharge efficiently. No performance figures beyond the rated capacity are supplied.

Installation notes

The battery slots into the internal compartment of the listed ThinkPad models using the existing screw points and connector. Alignment is straightforward when the correct model is matched to the part numbers above. The most common issue is ordering the wrong variant for a similar but incompatible ThinkPad chassis, so verify the exact model and Lenovo part number before fitting. No tools beyond a small Phillips screwdriver are typically required.
