SICHUAN CHANGHONG BATTERY CO., LTD.

PRODUCTS CATALOGUE Introduction So far,nickel cadmium rechargeable battery has become an obvious first choice for user looking for a reliable,long life,low maintenance system. As leading battery manufacturer in China, Sichuan Changhong Battery Co.,Ltd. has been specialized in the R&D , manufacturing , maintenance and after-service of the Ni-Cd rechargeable cells since decades ago. Advanced devices and continuous technology improvements guarantee the excellent performance and reliable quality of rechargeable battery. So far, Changhong pocket type Nickel cadmium rechargeable battery has been...

Changhong pocket type nickel cadmium rechargeable battery (hereinafter called into 3 kinds: low discharge rate (KPL),medium discharge rate (KPM) and high discharge rate (KPH), according to different applications (Namely, with different discharging current). Low discharge rate (KPL series) is suitable for the applications,that discharging current is lower than 0.5ItA. Medium discharge rate (KPM series) is applicable for those,that the discharging current is between 0.5ItA 3.5ItA,and high discharge rate (KPH series) is applicable for those, that discharging current is between 3.5ItA 7ItA....

Plates The main material of positive plate is nickel hydroxide, and the main material of negative plate is cadmium oxide. These active materials are separately retained in pocket formed nickel plated steel strip which is double perforated by a patented process. According to the capacity required, quantities of plate strips are mechanically linked together, then cut to the size corresponding to the plate width required and compressed to the final plate dimensions. At last, the plates are welded or assembled on the current collectors, which not only ensure the high mechanical strength,but...

Separator The Separators are made of plastic separator grids,which separate the plates and insulate the plate frames from each other. By providing a large space between the positive and negative plates and a generous quantity of electrolyte between plates,good electrolyte circulation and gas dissipation are provided , thus there is no stratification of the electrolyte as found with lead acid batteries. Terminal Pole The electrolyte used in Changhong pocket Terminal poles are made from nickel-plated steel bar with type Ni-Cd battery is a solution of good conductive performance and high...

Venting System Various kinds of vent plugs,such as flame-arresting flip-top vents,could be fitted with Changhong pocket type Ni-Cd batteries to give an effective and safe venting system. Cell Container The cell container is made from the engineering plastic (MBS or PP material) with high mechanical strength.

Common Troubles and Trouble Shootings Common Troubles Trouble Shootings Reasons Electrolyte has been used for a long times,and carbonate content is too much Electrolyte is improperly prepared or fail to the standard Top-up the distilled water and adjust the density of electrolyte,then overcharge the battery Too much harmful impurity in the electrolyte Clean the inside of the battery,and replace qualified electrolyte The battery is charged or discharged improperly Charge or discharge the battery in strict accordance with manufacturer instructions Short circuit or slight short circuit occurs...

PRODUCTS CATALOGUE Common Troubles Bubbles appear inside the battery Trouble Shootings Vent plug is blocked up Clean the vents with hot water to make it smooth or replace with new vent plugs Clean the battery immediately,keep it ventilated and dry Electrolyte level is too high Suck out redundant electrolyte,and adjust the electrolyte level to the height required Terminal poles and vent plugs are not well sealed Replace and tighten the sealing spare parts Electrolyte spills Electrolyte leakage Hard to repair,regardless influences in operating as princi ple Interior short circuit or too much...
