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 handheld device for jump starting a vehicle engine includes a rechargeable lithium ion battery pack and a microcontroller. The lithium ion battery is coupled to a power output port of the device through a FET smart switch actuated by the microcontroller. A vehicle battery isolation sensor connected in circuit with positive and negative polarity outputs detects the presence of a vehicle battery connected between the positive and negative polarity outputs. A reverse polarity sensor connected in circuit with the positive and negative polarity outputs detects the polarity of a vehicle battery connected between the positive and negative polarity outputs, such that the microcontroller will enable power to be delivered from the lithium ion power pack to the output port only when a good battery is connected to the output port and only when the battery is connected with proper polarity of positive and negative terminals.

Abstract: A handheld device for jump starting a vehicle engine includes a rechargeable lithium ion battery pack (32) and a microcontroller (1). The lithium ion battery is coupled to a power output port of the device through a power switch circuit (15) actuated by the microcontroller. A vehicle battery isolation sensor (12) connected in circuit with positive and negative polarity outputs detects the presence of a vehicle battery (72) connected between the positive and negative polarity outputs. A reverse polarity sensor (10) connected in circuit with the positive and negative polarity outputs detects the polarity of a vehicle battery connected between the positive and negative polarity outputs, such that the microcontroller will enable power to be delivered from the lithium ion power pack to the output port only when a good battery is connected to the output port and only when the battery is connected with proper polarity of positive and negative terminals.

Abstract: A portable or handheld device or apparatus for jump starting a vehicle engine having a depleted or discharged starting battery. The portable or handheld device or apparatus for jump starting a vehicle engine includes a rechargeable lithium-ion (Li-ion) battery pack and a battery cell equalization circuit configured to prevent overcharging of one or more individual lithium-ion battery cells, which can cause fire, damage to the battery pack and device or apparatus for jump starting a vehicle, or personal injury to a user.
