Lithium Ion Power Tool Battery Appraisal

Kobalt 80V Max 5.0 Ah Lithium-Ion Battery

The item is a Kobalt brand 80-volt maximum, 5.0 amp-hour (Ah) lithium-ion battery pack, primarily designed for use with Kobalt's line of 80V power tools. It has a robust, rectangular black plastic casing with prominent blue accents, particularly a thin blue stripe encircling the top edge and extending down the sides, which is characteristic of the Kobalt 80V series. The front face features a large, rectangular label with 'KOBALT' in white text on a blue background at the top, followed by '80V MAX' in white and yellow lettering. Below this, there's a smaller yellow box with 'LITHIUM ION' and '5.0 Ah' in white text on a gray background, signifying its power and battery technology. The sides and upper section of the battery case exhibit a textured, perforated surface with numerous small, circular ventilation holes, likely for heat dissipation during charging and discharge. The overall condition appears used, with a visible layer of dirt and dust accumulated on its surfaces, particularly noticeable in the perforated areas and on the top surface. There are no obvious signs of significant structural damage, cracks, or repairs, though the extensive dust suggests it has been used in a workshop or outdoor environment. The plastic material itself has a matte finish, which appears slightly worn in places due to general use. The internal components, such as the battery cells and protective circuitry, are not visible. No manufacturing dates or specific model numbers beyond the '5.0 Ah' rating are discernible from the image. The construction appears sturdy, indicating a durable design suitable for demanding applications. It represents a modern power tool accessory, likely manufactured within the last decade given the prevalence of lithium-ion technology in power tools.
