Kstar battery 12V100AH ??cheap stock are trying to do the country's most practical cheapest battery supplier. We strive to make the country and the major European markets battery supplier. We strive to make the country the best quality, long-lasting battery power suppliers. We have automated battery production line also has a battery perennial foreign orders require external electronics factory production and processing. We work towards a better, stronger, faster, better sound to provide customers with quality products and services into the goal. Note the use of a battery KSTAR, different types, different brands, different capacities, different recency batteries generally can not be mixed, otherwise they will not match and pull the bad battery. 2, the battery is 100% charged the factory, to be careful to avoid short circuit; when installing insulated tools, wear insulated gloves to prevent short circuits and electric shock. Battery installation should be a qualified technician to implement multiple batteries in series, the battery should be a positive and the other negative battery linked, so again the group consisting of a battery, then the battery positive and UPS is connected to the positive (red for positive), a negative electrode of the battery pack is connected to the UPS (Black represents negative), and properly connected securely. When the polarity of the connection error, can cause damage to the battery or machine. 3, the initial use, the battery shall be fully charged before use, if not by the full charge will cause its performance can not play; if long-term use, the battery will self-discharge gradually reduce its capacity, it is recommended every three months to add power once. 4, the battery should be away from the use of organic solvents, well-ventilated, dry, clean environment at 5 ℃ -35 ℃ longest service life. 5, should try to avoid excessive battery discharge, the UPS is done and should be closed after the UPS power switch, and after utility power is restored charged immediately, otherwise it will cause deterioration of battery performance. Kstar battery characteristics and application: No maintenance: during the entire service life of the battery without adding water rehydration. High reliability, long life, special sealing structure and flame retardant case, does not produce in the course of electrolyte leakage defect, but the fire does not occur. Weight, volume, high energy, internal resistance, high output power. Self-discharge, 20 ℃ under the monthly self-discharge rate is not greater than 2%. Man charged the factory, no flow of electrolyte transport safety. Wide temperature range: Standard Series Battery (-30 ℃ ~ 50 ℃), high temperature range (-45 ℃ ~ 70 ℃) without balancing charge, due to resistance of individual cells, capacity, consistency of quality float voltage to ensure that the battery during use without a balanced charge. Good recovery performance: the battery discharge to 0 volts, short circuit for 30 days, can still charge to restore its capacity. Solid copper terminals / Lo two kinds to choose from maintenance-free batteries can be charged should be noted: The power of the charging voltage at all the time to maintain a constant value, with the gradual increase in the battery terminal voltage, the current decreases. Compared to the constant current charging method, the charging process is more close to the optimal charging curve. Fast charging with a constant voltage, as shown in Fig. Due to the low initial charge battery electromotive force, the charging current is large, as the charge of conduct, the current will gradually decrease, therefore, just a simple control system. This method of charging water electrolysis little to prevent the battery overcharge. But in the initial charge current is too large, resulting in a significant impact on battery life, and easy to make the battery plates bend, causing the battery scrap. In view of the above drawback, constant voltage charging is rarely used, only the power supply voltage and the charging current is large use. For example, automobile is running, the battery is charging to constant voltage charging method. Maintenance-free batteries, greatly facilitate the user's daily use, to avoid the daily care and maintenance. In fact, the basic structure of the maintenance-free battery and common battery is the same, the difference is that in order to achieve long-term maintenance-free batteries do not add distilled water or electrolyte purpose, exhaust system and general battery is significantly different. Ordinary battery can be screwed down on top of the six closures, there are vent above closures are used to raise, check the electrolyte and gas emissions. For both gas emissions and reducing the electrolyte overflow vent plugs from the inside to the outside is generally not straight, but staggered up and down or roundabout.
