Abstract: The invention discloses a battery covering structure with replaceable terminals, comprising a covering and terminals, the terminals are located on the covering, and the covering is used for connecting with the battery body, the terminals are detachably connected with the covering. The invention makes the replacement of terminals convenient and quick, which enables the structure to be matched with various types of automobiles and motorcycles, and is beneficial to improving the applicability of battery.

Abstract: 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.

Abstract: The present invention discloses a combined starting power supply, comprising a lead acid battery, a lithium battery and a lithium battery protection circuit, wherein the lithium battery protection circuit comprises a first input, a second input, a first output and a second output; a negative electrode of the lithium battery is connected to the first input, and a positive electrode of the lithium battery is connected to the second input; and a negative electrode of the lead acid battery is connected to the first output, and a positive electrode of the lead acid battery is connected to the second output. The combined starting power supply of the present invention increases the safety thereof by adopting a lithium battery; and the lithium-ion battery is always put in a safe working state by means of the lithium battery protection circuit during charging and discharging processes.

Abstract: A replaceable and versatile hermetical lead-acid cell comprises a top cover and a casing. The top cover has a cap disposed at its top portion. The top cover and casing are sealed together by resin sealable glue filled therebetween. Plural electrode plates, between which dilute sulfuric acid is filled, are positioned in the casing. In addition, a divider is placed between every two electrode plates. Four electrode terminal posts are further provided at the top portion of the top cover and are adjacent to four corners of the top cover. The invention can replace various kinds of cells in marketplace, meet requirements of difference motorcycle, and improve capacity of the cell.
