Branch, maintenance-free batteries battery 12V100AH ??name suggests the biggest feature is the "maintenance-free" maintenance-free battery As the name suggests the biggest feature is the "maintenance." And lead-acid battery consumption is very small compared to its electrolyte during the life of the basic need to add distilled water. It also has a shock, temperature, small size, low self-discharge characteristics. Of course relative, its price will be more expensive than lead-acid batteries Branch battery 12v100ah1, safety performance is good 2, 3 good discharge performance, good resistance to shock four, five good impact resistance, resistance to over-discharge 6, good resistance to charge 7, good resistance to high current battery Kehua main features: 1, good safety performance: No electrolyte leakage under normal use, no cell expansion and rupture. 2, the discharge performance: stable discharge voltage, discharge platform gently. 3, good resistance to shock: fully charged battery completely fixed to 4mm amplitude, frequency vibration 16.7hz one hour, no leakage, no cell expansion and cracking, open circuit voltage is normal. 4, good impact resistance: the battery is fully charged state natural height from 20cm down to 1cm thick hardwood board 3 times no leakage, no cell expansion and cracking, open circuit voltage is normal. 5, resistance to over-discharge: 25 degrees Celsius, the battery is fully charged state of constant resistance discharge 3 weeks (only the equivalent resistance of the battery discharge requirements 1ca resistance) to restore the capacity of more than 75% 6, good resistance to charge: 25 Celsius, fully charged battery 0.1ca charge for 48 hours, no leakage, no cell expansion and cracking, open circuit voltage is normal, the capacity retention rate of over 95%. 7, resistance to high current: fully charged battery 2ca discharge discharge for 5 minutes or 10ca 5 seconds. No conductive part of the fuse, without the appearance of deformation precautions when installing the battery installed, be sure to observe the following: 1.1 Do not install batteries in the vicinity of the sealed space or fire, or else there is a danger of explosion and fire. 1.2 Do not use vinyl film class may lead to something static battery cover, sometimes explode when static electricity. 1.3 Do not place where it is possible to install the battery water, otherwise electric shock, fire hazard. 1.4 Do not install the battery at temperatures above -40 ° c ~ 60 ° c environment. 1.5 Do not use the battery in dusty place, otherwise the battery may cause a short circuit. 1.6 The use of the battery into the box, pay attention to ventilation. 1.7 Do not sticky labels or class of objects to suppress the cover, because the cover underneath the exhaust valve, the gas generated in the battery will not be able to escape. 1. The number 8 in parallel - float charging, plug-in terminal of the battery can be associated with up to three columns, screw-terminals are not particularly limited, but the increase in the number of small parallel reliability. In addition, parallel connection, it is necessary to consider making the connection between the conductor and the contact resistance equivalent to the columns, each column to make the charge and discharge the battery to maintain a balanced, do not actually use more than three. 1.9 use different capacity and different old and new batteries from different manufacturers, due to the different values ??of its properties has the potential to damage the battery and the machine, so please avoid using. Features capacity range (C10): 5.5Ah-200Ah voltage: 12V; design float life: at 25 ℃ ± 5 ℃ environment, 12V series for 15 years; cycle life: under standard conditions, A400-12V series 25% DOD cycle 2950 times; self-discharge rate ≤2% / month; high charge acceptance, when the festival saving; Wide operating temperature range: -20 ℃ ~ 55 ℃ shelf life: After fully charged, standing at 25 ℃ environment stored for 2 years, the battery residual capacity is still more than 50%, after charging, the battery capacity can be restored to 100% of the rated capacity. Good anti deep discharge performance: 100% after discharge may continue to receive the load, the charge to restore the original capacity after four weeks. Structural features Electrolyte: gel state, no electrolyte stratification, good battery cycle performance; low electrolyte density, slow to grid corrosion, long battery float life; fumed silica: imported from Germany, good dispersion properties, stable performance; plate: radial ribs design, paste type active material, a good high-current discharge performance; clapboard: Europe Amersil production of PVC-SiO2 gel batteries dedicated partitions, internal resistance, high porosity, and long service life; excess electrolyte design: a carrier liquid electrolyte volume high, full of plates, partitions and the housing cavity, battery heat, less prone to thermal runaway; colloid coated extremely tight group: prevent the active material shedding; patented gel battery safety valve, High sensitivity, safe and reliable; the battery case: slot cover thick design, impact-resistant, shock-resistant ABS material, transportation, use, no leakage, drum shell, and dangerous, safe and reliable;
