Germany sunshine battery advantages: 1, gel electrolyte internal short circuit. Heat capacity, heat dissipation ability to avoid general battery is easy to produce thermal runaway phenomenon, and thus extremely reliable operation at high temperatures, the battery does not produce "dry" phenomenon, operating temperature range. 2, since the battery is a gummy solid, uniform electrolyte concentration, the presence of an acid stratification phenomenon. 3, the acid concentration is low, weak corrosion to the plate, and unique tubular plate, long battery life. 4, no antimony alloy battery plate, very low self-discharge of the battery. 20 ° C storage for two years, there are more than 50% of capacity within two years without refilling electricity. 5, super withstand deep discharge and high-current discharge capacity, with over charge and over-discharge self-protection performance. 6, battery anti deep discharge capability, and can continue after the 100% discharge connected to the load on the charge to restore the original capacity within four weeks. 7, using a highly sensitive low voltage umbrella type valve, so that the battery is safer to use and reliable. 8, using a multilayer acidproof rubber ring sliding seal, and to ensure the sealing performance of the growth of the life of post-pole. Product quality assurance commitment: pre-sales technical consulting: to help users design and provide free technical advice .2 delivery date and place of delivery: to ensure delivery to the user-specified location on time and within the specified time .3. Installation supervision: demand side requirements responsible for equipment installation `debug` technical guidance .4. preliminary inspection of the product `test run` final inspection: actively cooperate with the preliminary inspection of the demand-side equipment `test run the` final inspection work, and according to the user's requirements. product performance testing to ensure equipment uptime .5 Product warranty: three-year warranty, during the warranty period, we will be free of charge to replace the product failure due to technical problems and quality of raw materials `design and manufacturing process, and the buyer is unable to deal with the main problem, provide free replacement service, timely solutions to the various problems and repair products exist. should pay attention to matters that Germany sunshine battery charging as follows: 1) The batteries are recommended +5 ℃ ~ +30 ℃ (best 25 ℃) temperature conditions, high temperatures will shorten the life span, low-temperature reduction in capacity; 2) different brands, different capacities, different new and old batteries non-mixed use; 3) will produce hydrogen battery use, so away from sources of ignition, maintain ventilation to prevent an explosion; 4) maintain a clean environment, excessive dust can cause the battery short circuit; 5) battery discharge should recharge the battery is not fully charged and then discharge will cause the battery capacity reduce or even damage, so you must configure the appropriate charger; 6) UPS load light (such as 1KVAUPS with 150VA load) may cause battery deep discharge, should be avoided; 7) appropriate discharge contribute to the activation of the battery , such as long-term non-stop city electricity, should be manually battery discharge, 2 to 4 times a year, you can take advantage of existing load discharge time for the back-up time of 1/4 to 1/3; 8) long-term disabled battery (UPS) should after charging, storage, and every six months requires the battery to be charged and discharged once, generally the battery float about 4 to 10 hours, and the state of the battery inverter work 2 to 3 minutes
