Notice The following notes should be abided in operating: 1. Fireproofing This series of battery can generate explosive gas [hydrogen and oxygen],Explosive gas is generated when the low capacity cells are doing recovery charging in regular complementary charging.Battery room must contain ventilation devices and keep away from naked fire. 2. Electrolyte Prapering and Filling For protection, wear working clothes, glasses, rubber apron, rubber gloves and rubber overshoes during electrolyte filling. There should be boric acid of 3% for reservation. When the electrolyte spills on the skin, clean...

INSTALLATION AND OPERATING INSTRUCTIONS 1.1 Brief introduction Nowadays, the most popular rechargeable batteries in industrial application are nickel cadmium battery and lead acid battery. Compared with lead-acid cell, the maintenance of Ni-Cd cell is easier and the service life is longer. The manual is mainly described installation and which is helpful for knowing well about structure, performance and correct maintenance methods. Before operating, please read the manual carefully. 1.2 Structure We can provide 3 kinds of pocket type alkaline batteries: H, M, and L. For H series, it is high...

to be battery pack. Single cells are connected by intercell connectors, for convenient transportation, handles are always installed on the crates, the quantity of single cells in the battery pack lies on its basic dimension and weight. 1.3 Chemical reaction in charging and discharging For pocket type nickel cadmium rechargeable battery, Ni[OH]2 is used as positive materials, while Cd[OH]a is used as negative materials. Electrolyte is KOH aqueous solution with a little LiOH, to improve service life and high temperature performance of the battery. Electrolyte works only for ion transmitting...

under normal temperature, the essential resistance is 20% higher when discharged by 90%, and it is 80% higher when discharged by 90%, once the temperature is lower, it also will be bigger, for instance, it will be 15% higher under 0°C than that under normal temperature. Flip-top vents - Material: polypropylene. Cell container - Material: PP/ABS/MBS Plate group bus Connects the plate tabs with the terminal post. Plate tabs and terminal post are projection welded to the plate group bus Plate frame Seals the place - pocket and serves as a current collector Cell cover Material: PP/ABS Terminal...

2.4.2 Ventilation When the battery is installed in small room or closed carriage, ventilation devices are always required. At the later stage of charging, the battery will vent gas (mixed gas of H2 and Os). When installing reasonable ventilation systems in the battery room, it is necessary to calculate the producing speed of Ha and ensure the concentration of H3 produced in the room keeps in a safe range. The theoretic safe limit concentration of H2 is 4%. The exhaust requirement in the battery room can be calculated according to the following methods: 1 Ah of overcharge can electrolyze...

on end, and install carefully according to arrangement drawings, avoiding polarity confusion. If you are not familiar with arranging cells, please read this article carefully, Changhong has decades of experiences on the battery installation and developed a series of standard battery layouts, whether the battery is being installed on the rack, in the cabinet, or on the open ground, The same configuration principles can be applied. In general, there are two ways to configure the battery. The first method is length-to length connection, shown in figure A. The second method is width-to-width...

3.1 Preparation before initial charge After installing and connecting, the battery should be fully charged as soon as possible, before that, please inspect AC current and the charger, ensuring they can be normally operated, measure the voltages of battery pack and single cells, electrolyte density and temperature, ensuring there is no problem. Then connect the positive and negative poles correspondingly of the battery and the charger. 3.2 Charging Each cell should be charged according to the standard current [0.2I,A], cells of the same model can be charged together, while the different...

3.3 Treatment after initial charge After initial charge, since the battery needs to do all kinds of performance tests, it will be discharged more or less, before operation, it should be charged by the current of 0.21^ for 8h. Notes: check whether the electrolyte level is normal or not after charging, if it is much lower than the max. level, please fill distilled water or deionized water to the proper level. 3.4 Storage after initial charge If the battery is not used at once after initial charge, the following methods should be done for electrolyte storage. If the fully charged battery...
