Abstract: A battery, for example, a rechargeable battery (e.g. lithium ion battery) having a casing with battery terminals. The casing, for example, includes an upper section, middle section, and lower section connected together. The battery can be connected to one or more battery trays having the same height or different heights for various applications.

Abstract: A rechargeable battery jump starting device having detachable positive and negative cables. The rechargeable battery jump starting device, including a rechargeable battery connected to a positive cam-lock cable connecting device and a negative cam-lock cable connecting device. The rechargeable battery jump starting device can include a highly electrically conductive frame connecting the rechargeable battery to the cam-lock cable devices.

Abstract: A battery assembly device for a battery jump starting device. The battery assembly is configured to maximize electrical conductivity from a battery pack of the battery jump starting device to a battery to be recharged.

Abstract: A rechargeable battery assembly includes a rechargeable battery having a positive terminal and a negative terminal, and a rigid electrically conductive frame electrically connected to at least one of the positive terminal or the negative terminal of the rechargeable battery. The rigid electrically conductive frame is bent along multiple axes and includes a plurality of conductive frame members that are mechanically coupled together. The rigid electrically conductive frame surrounds the rechargeable battery on at least five sides, thereby providing structural stability to the rechargeable battery assembly during storage and use.

Abstract: A rechargeable battery jump starting device with a discharged battery pre-conditioning system to facilitate boosting the discharged battery to jump start a vehicle or equipment engine. The pre-conditioning increases the operating voltage to the discharged battery during the pre-conditioning phase.

Abstract: A rechargeable battery jump starting device and a rechargeable battery assembly for use in the portable rechargeable battery jump starting device. The portable rechargeable battery jump starting device maximizes the power conducted from the rechargeable battery assembly to a battery being jump started.

Abstract: A rechargeable battery jump starting device with a leapfrog charging system. The leapfrog charging system, for example, can sequentially charge multiple batteries of the rechargeable battery jump starting device.

Abstract: A jump starting apparatus for boosting or charging a depleted or discharged battery having a positive polarity battery terminal and a negative polarity battery terminal includes a rechargeable battery, an output port, a battery cable assembly, and a safety control system or circuit.
