The invention relates to a battery, in particular to a hybrid battery. The invention provides a hybrid battery that is easy to replace a terminal block and has low maintenance cost, comprising a casing and at least two different sets of battery cells arranged in the casing, wherein the casing is detachably provided with a terminal block, the terminal block is electrically connected with the electrode of the battery cells. When in use, the terminal block in the invention can be detached from the hybrid battery in time if the terminal block is oxidized and blackened for long time use, and only the terminal block is replaced instead of the entire hybrid battery, therefore, the maintenance cost of the hybrid battery is low.

Disclosed is a non-lead conductive cap for a battery terminal and battery. The battery may comprise a battery housing and a positive and negative terminal, the positive and negative terminal being accessible through the battery housing; wherein the positive and negative terminal further comprise an electrically conductive cap mounted on both the positive and negative terminal, wherein the electrically conductive cap does not comprise lead.

Battery contact with surface texturing. Exemplary battery contacts are located within a battery pack. The battery pack is operable to provide power to a device through a device contact of the device. The battery pack includes a battery pack housing, at least one battery cell located within the battery pack housing, and battery contacts including a positive terminal and a negative terminal. The battery contacts are configured to engage the device contact of the device and allow electric current to transfer from the battery pack to the device. The battery contacts define a surface having a surface texture. The surface texture includes raised portions for contacting the device contact to allow electric current to transfer from the battery pack to the device. The surface texture also includes recessed regions spaced away from the surface and for providing a space between the battery contacts and the device contact.

A battery terminal cover is provided. The battery terminal cover has a base arranged to cover a battery terminal root, a tower arranged to cover a battery terminal post, and a projection coupled to the battery terminal cover. The projection has a retention area for temporary storage of a later used fastener for coupling to the battery terminal post. A battery is also provided.

A rechargeable battery includes: an electrode assembly including a first electrode, a second electrode, and a separator between the first electrode and the second electrode; a case connected to the first electrode to house the electrode assembly and including an opening to expose the electrode assembly; a cap plate coupled with the case to cover an outer region of the opening and including a through-hole to expose a center region of the opening; and a terminal plate bonded to and insulated from the cap plate to cover the through-hole and connected to the second electrode, and the outer surface of the case has a first protrusions-and-depressions shape.

A quick change battery clamp includes a first clamp body, a second clamp body, and a handle assembly. The second clamp body is coupled to the first clamp body.
