Features: 1: Long Mileage: Mileage than 15% of the market similar to enhance battery; 2: long life: to extend battery life than 8% of the market similar; 3: Environmental non Cadmium: Cadmium-green; [How to use the correct Battery] battery is the power source of electric bicycles, but also a consumable, and higher prices, so to keep the battery in good working condition, extending its life by a great value. The following are some of the battery maintenance methods: 1: battery installed firmly on the bike, the rider line to prevent the battery from vibration damage. 2: Always remove the battery cover of dust, dirt, keep the battery clean and dry to prevent battery self-discharge. 3: Absolutely not let the battery power is low for a long period of state, and every night to develop a good habit to charge the battery. 4: Electric bike just started, started to use pedal power to avoid the discharge current is too large and damage the battery. 5: When cycling, be careful not to let the battery discharge, over-discharge likely to cause serious loss of battery power, thus greatly shortening its life. Electric bikes are generally under-voltage protection function, when the battery display has a display lights should immediately charge the battery to avoid battery discharge. The following factors may shorten battery life: 1: Duplicate deep discharge; 2: Repeat after shallow depth of charge and discharge; 3: The outside temperature is too high; 4: Overcharge - especially the tiny floating charge; 5: Over large charging current; 6: When a charged battery if not used for a long time, especially in high temperature environment, will lead to reduced self-discharge and capacity. To grasp the battery case, you should regularly check the battery to the following: 1: The connection between the battery and the battery pack between the DC power supply is loose, corrosion, damage and other phenomena, repair if necessary. 2: the battery is damaged, leakage and other anomalies, replace if necessary. 3: The voltage of each battery charge and discharge capacity is within the normal range, if necessary, the battery charge and discharge cycle test. Note: 1: battery in the same group use the same box, do not different specifications, different manufacturers, different old and new batteries together; 2: Avoid short circuit between positive and negative; 3: Avoid using the battery to protect the voltage again after; 4: Use process should avoid strong vibration or mechanical damage; 5: charging and discharging process of using Do not exceed the technical parameters (voltage, current) range required; 6: Keep away from heat, sources of ignition, avoid direct sunlight; 7: Keep away from children; 8 : Battery avoid during maintenance sulfuric acid solution contacts the eyes or on the skin, such as occasionally occur touches the skin, on clothing, they must immediately with plenty of water; serious when required hospital treatment; 9: prohibit the use of chemical cleaning agents, gasoline, thinner and other organic solvents to clean the battery, otherwise it will damage the battery casing; 10: Abandoned old batteries should be stored centrally to the designated location or recovered by the battery manufacturers; 11: installation, use and maintenance process, you should use insulated tools and features Insulated gloves to prevent electrical shock and cause a short circuit. 12: When the battery is abnormal, treatment should be professionals or contact your dealer to prohibit dismantle repair. 13: The battery electric vehicle batteries, such as for other purposes, please consult the manufacturer. Common Faults and exclusion: 1: Electric car battery need to maintain it Answer:? Needs. Due to the battery during the charging process will produce hydrogen gas, most of the gas will be combined into the water in the battery, only a small portion of the gas through the relief valve discharge the battery, the battery will result in long-term dehydration. So it is best to store the battery operation or repair shop for maintenance dosing 2 power box hot when you use an electric car in 8-10 months later or charge: electric bicycles continued mileage is short if the battery problem? Answer: Not necessarily. When the battery aging, the capacity drops, continues the course becomes shorter, but when the battery does not belong to the following questions will lead to continued mileage shorter: 1) When the motor efficiency drops, do useful work increases, wasteful consumption, so continue the mileage shorter; 2) inferior charger to charge the battery due to charge every day, so that the battery caused by insufficient capacity to continue the mileage dropped shorter; 3) to make the electric car controller bad starting current is too large, the starting time is too long waste of electricity, resulting in shorter continued line of electric vehicles; 4) the poor quality of electric vehicles all moving parts friction coefficient is too large, or mechanical transmission resistance is too large, it can be a waste of electricity, resulting in continued mileage shorter 3: Summer use of electric vehicles should pay attention to what matters? 1) Avoid sun exposure at high temperatures, is prohibited in high temperature environments charging; 2) Avoid driving at high temperatures immediately after charging, to prevent long charging time (normal eight hours or so); 3) When charging the battery is hot or not to switch the power box green light, it is timely to battery operation shop or repair shop for inspection and maintenance of the battery or charger; 4: Winter use of electric vehicles which will be the case, how should try to avoid a) the use of electric vehicles in winter you'll feel Continued mileage decreased? (North is more obvious), this is a normal phenomenon; 2) due to low temperatures, the battery charge acceptance next lower ability Furthermore electrolyte viscosity, increase the electrochemical reaction resistance, resulting in decreased battery capacity. So you avoid the electric car on the outside overnight or when charging at low temperatures in winter;
