Detailed Product Description: | Yuasa maintenance-free batteries NP38-12 latest offer our commitment to original authentic, fake a compensable 10, free home repair .13718107657. ■ battery life under normal condition, the battery can be used at least 300 times if a rechargeable battery good battery section provided significantly reduced, indicating that the battery life has come to. It should be replaced with a new battery. Save explanation lithium compact, and can stock energy, but after a long time without charging, battery performance will be a long time without damage ● if the battery before storing the battery run out. ● The battery should not be removed from the camera or charger. ● capped stored in a cool place * Batteries should be stored at + 15 ℃ --25 ℃ between dry place * Do not store batteries in warm or temperature where ■ carrying the battery in order to avoid damage to the battery, please note the following: ● Do Let battery metal parts and other metal contact ● Do not go near an open flame or dropped into the fire ● Do not attempt to disassemble or modify the battery ● Do not use any other standard charger to charge the battery. To avoid damage or shorten the life of the battery, you should note the following: ● Do not allow the battery to fall fetters or violent impact with other objects ● Do not put the battery soaked in water to ensure that the battery can be the best working condition, note the following considerations: ● holding ● Clean the battery terminals in a dry, cool and ventilated place to save, in the heat of high temperature will shorten the battery life battery decentralized use for some time, the body and the battery itself gets hot, this is normal and not a defect, if you want a long shot or preview images, please use with matching ac power transformer ■ Specification Rated voltage dc3.7v rated capacity 900mah Operating temperature 0 ℃ - + 40 ℃ (+ 32 ° - + 104 ° f) Dimensions 35.2mm × 53mm × 7.0mm (w × h × d) Weight Approx 30g * Specifications are subject to change without notice. Yuasa Battery Features: long battery life, high capacity, superior recovery after discharge; battery air tightness, safe, fast charge; 1, good safety performance: electrolytic Yuasa Battery under normal use fluid leakage, no cell expansion and rupture. 2, the discharge performance: stable Yuasa battery discharge voltage, discharge platform gently. 3, good resistance to shock: Yuasa battery is fully charged battery completely fixed to 4mm amplitude and frequency of vibration 16.7HZ one hour, no leakage, no cell expansion and cracking, open circuit voltage is normal. 4, good impact resistance: Yuasa battery is fully charged battery from 20CM height naturally fall to the 1CM thick hardwood board 3 times no leakage, no cell expansion and cracking, open circuit voltage is normal. Structure of the battery leak fluid, with a maintenance-free properties; battery has anti-overcharge, anti-over-discharge, vibration, shock-resistant features, the battery can be placed anywhere, to facilitate the protection and use; improve battery energy density to achieve a battery size and weight; battery to meet customer needs, has been widely used in various fields 5, resistance to over-discharge: Yuasa Battery 25 degrees Celsius, the battery is fully charged state resistance of the discharge given 3 weeks (resistance only equivalent The battery discharge requirements 1CA resistance) to restore the capacity of more than 75% 6, good resistance to charge: Yuasa Battery 25 degrees Celsius, fully charged battery 0.1CA charge for 48 hours, no leakage, no cell expansion and rupture, open circuit voltage is normal, the capacity retention rate of 95% to 7, good resistance to high current: fully charged battery Yuasa Battery 2CA state of discharge for 5 minutes or 10CA discharge for 5 minutes. No guide part of the fuse, without the appearance of deformation. Yuasa battery maintenance and maintenance: the use of UPS power supply system in the process, people often one-sided that the battery is maintenance-free and not take this seriously. However, our data show that the proportion due to battery failure caused by a host failure or UPS is not working properly is about 1/3. Thus, strengthening the proper use and maintenance of the UPS battery to extend battery life and reduce UPS power supply system failure rate, with more and more important. In addition to an optional battery other than regular brands, the following aspects should properly use and maintain the batteries: 1. To maintain the appropriate environmental temperature. Important factors that affect battery life is ambient temperature, ambient temperature is usually the best battery manufacturers claim is between 20 ℃ ~ 25 ℃. Although the temperature rise of the battery discharge capacity has increased, but the cost is greatly reduced battery life. According to tests measuring the ambient temperature once more than 25 ℃, each increased 10 ℃, the battery life would be shortened by half. UPS batteries currently used are generally VRLA batteries, universal design life of five years, which can be achieved at battery manufacturer demanding environments. Less than the required environmental requirements, there is a great difference in the length of its life. In addition, the increase in ambient temperature can cause the battery internal chemical activity increased, resulting in a lot of heat, in turn prompting the ambient temperature, this vicious cycle will accelerate shorten battery life. 2. Regularly charge and discharge. UPS power supply system in the float voltage and discharge voltage at the factory have been commissioning rating, and discharge size is increasing as the load increases, the use should be reasonable to adjust the load, such as a control computer and other electronic equipment Use several. In general, the load should not exceed 60% UPS rated load. Within this range, the battery will not over-discharge. UPS connected to the mains due to long-term, high-quality power supply, power outages are rare use of the environment, the battery will be a long period of floating charge state, a long time will cause the battery chemical energy and electrical energy into each activity decreased, accelerated aging shorten life. Thus, generally every two to three months should be fully discharged once, discharge time can be determined based on the battery capacity and load size. After a full load discharge is complete, according to the provisions recharge more than 8 hours. |
