In one embodiment, battery pack receptacle/adapter  520  embodiments may hold battery packs having different types of voltages, such as 12 V., 18 V., 24 V., 36 V., etc. In one embodiment, battery pack receptacle/adapter  520  embodiments include a circuit that limits voltage/amperage for different types of electronic devices, which may have different power requirements. It should be noted that cordless device battery packs typically include a specifically designed housing with specific designed housing contours and electrical connections that are unique to each brand or manufacturer. The specific designed contours and electrical connections (or electrical contacts) are uniquely designed for the brand or manufacturer&#39;s cordless tools and battery pack chargers. One brand or manufacturer&#39;s battery packs do not work in other brand or manufacturer&#39;s cordless tools or battery pack chargers since the electrical contacts and contours are different from each other. The battery packs include multiple rechargeable batteries that are included in a housing that transfers the combined voltage from the multiple rechargeable batteries through electrical contacts on the exterior of the housing. In this way, a user just needs to slide in or insert the battery pack into a cordless power tool to take advantage of the combined voltage or power from the multiple batteries internal to the battery pack.
