The battery pack includes one or more cells. The cell includes first and second electrodes and an electrolyte. One or both of the first and second electrodes include a support layer and an electrochemically reactive species on the support layer and in contact with the electrolyte, and wherein the support layer includes a high specific surface area material.

Abstract: A tool comprising a working head adapted to perform an operation on a workpiece in response to an activation signal, a location detector connected to the tool to determine a geographic location of the tool, a memory and a processor, wherein in response to the activation signal, the processor causes the working head to perform the operation on the workpiece and records the geographic location of the tool at the time the operation was performed on the workpiece in the memory.

Abstract: Portable, hand-held, battery operated, hydraulic tools are provided with a tool frame, a force sensor, and a location detector. A piston actuated by a hydraulic system within the tool frame applies force to the working head to perform a task, such as to apply a crimp to an electrical connector. The tool determines the maximum force applied to the crimp and records that maximum force along with the geographic location of the tool when the crimp was formed. The maximum force provides an indication of the quality of the crimp and the recorded location allows a potentially defective crimp to be located.

Abstract: A multi-stage trigger assembly for portable, hand-held, battery powered tools is provided. The tool may be configured as a crimping tool, a cutting tool or other type of tool. The tool has an in-line handle assembly and a working head assembly. The trigger assembly has a first stage that is a manual operation and a second stage that is an electro-mechanical operation.

Abstract: Portable, hand held, battery operated, hydraulic tools are provided with a tool frame and one or more interchangeable working heads. When the working head is connected with the tool frame, a piston actuated by a hydraulic system within the tool frame applies force to the working head to perform a task. The tool includes a sensor for detecting the type of head connected with the tool and a mechanism for adjusting the amount of force applied to the head by the hydraulic system based on the detected head type.

Abstract: Portable, hand held, battery operated, dieless, hydraulic crimping tools are provided with a working head and a tool frame. The working head has a head frame with an open access to a working area of the working head. The open access may be in the form of a C-shape. The working head has a nest to receive a crimping member. An indentor is attached to a piston within the tool frame. The piston moves the indentor between a home position adjacent the tool frame and an indenting position where the indentor impacts the crimping member.

Abstract: Portable, hand-held hydraulic tools having a modular power unit within a handle assembly and a working head assembly mated to the handle assembly. The working head assembly can have a pair of movable jaws or a movable jaw and a fixed jaw. The jaws can be configured to perform different operating operations, such as crimping operations and cutting operations.

Abstract: Portable, hand held, battery operated, hydraulic tools are provided with a tool frame and one or more interchangeable working heads. When the working head is connected with the tool frame, a piston actuated by a hydraulic system within the tool frame applies force to the working head to perform a task. The tool includes a sensor for detecting the type of head connected with the tool and a mechanism for adjusting the amount of force applied to the head by the hydraulic system based on the detected head type.

Abstract: The present disclosure provides a mini or micro hand-held, portable, battery-powered 2-3 ton crimp tool capable of crimping conductors ranging between #22 AWG and #2 AWG to a termination. The crimp tool has a C-shaped head portion that uses linear motion to perform the crimp operation.

Abstract: Portable, hand held, battery operated, hydraulic tools are provided with a tool frame and one or more interchangeable working heads. When the working head is connected with the tool frame, a piston actuated by a hydraulic system within the tool frame applies force to the working head to perform a task. A coupling mechanism holds the working head to the tool frame. The coupling mechanism allows the working head to be removed from the tool frame and another working head to be joined to the tool frame. The coupling mechanism can hold the working head at a fixed rotational angle with respect to the tool frame. The coupling mechanism can also allow the working head to rotate with respect to the tool frame.

Abstract: A portable, hand held hydraulic cutting tool having an in-line handle assembly and a working head assembly. The handle assembly has a tool frame portion and a neck portion. The working head assembly has a pair of jaw members joined so that they are movable relative to each other and held in place by a locking pin. Each jaw member has a cutting blade attached thereto. Each jaw member can be tapered and can include weight reducing pockets defined in respective sidewalls. Each jaw member includes a raised tab on an outside edge that mates with a respective tab notch in a yoke of the neck portion of the handle assembly. When the locking pin is in an extended position, the jaw members of the tool can separate and rotate away from one another until their respective locking tabs engage their respective locking tab opening, connecting the jaw members to the yoke of the neck portion of the handle assembly.
