Dr. Battery JK6Y6 CF5RH laptop battery 11.4V 3600mAh for Dell Inspiron Latitude Vostro

Professional Series Li-polymer replacement

This Dr. Battery Professional Series unit is a brand-new lithium-polymer replacement battery engineered for select Dell Inspiron, Latitude and Vostro laptops. It restores reliable mobile power for everyday home, school and office workloads. The 11.4V 3600mAh pack uses OEM-grade cells tested for stable performance and long cycle life. Built-in protection guards against over-charging, over-discharging, overheating and short-circuit conditions.

Slim internal form factor fits supported chassis

The battery measures 8.0 by 1.5 by 0.8 units and weighs 0.4 units, matching the slim internal profile required by the listed ultraportable and 2-in-1 models. It connects directly to the motherboard header without cables or adapters, so installation is a straightforward swap inside the service bay. The compact footprint leaves no clearance issues for surrounding components or thermal solutions. Users should verify the original part number such as CF5RH, JK6Y6 or C5KG6 before fitting.

Chemistry and voltage define the practical ceiling

Lithium-polymer chemistry at 11.4V sets the energy ceiling at 3600mAh; runtime scales with the host system's power draw and cannot exceed this physical capacity. The pack does not support fast-charge protocols beyond the laptop's stock controller, so recharge times remain tied to the original AC adapter. Capacity will gradually diminish over repeated cycles, a normal trait of Li-polymer cells. Buyers needing higher capacity or a different voltage must choose a battery the laptop's firmware recognises.
