The definition of SPT series is coming from General purpose.?Feature in details·Sealed Construction and leakproof?All the acid inside the battery is suspended in a formulated non-woven glass mat separator and it is absorbed in the manner. This construction ensure leakproof during normal operation.·Maintenance FreeFor SunStone batteries, there is no need to check or add water or any other specific gravity during the whole service life of the batteries.·Electrolyte Suspension DesignSunStone batteries utilize an electrolyte suspension system consisting of a high porosity, glass fiber material which is conjunction with plate, totally absorb and contain the electrolyte. No silica gels or any other contaminants are used.·Gas GenerationIn the normal charge/discharge usage the gasses generated and recombined during the normal operation. More than 99% of the gases generated are efficiently recombined.·Safety and Automatic Valve SystemIf the pressure is over 2-5 psi the safety valve will automatically open and reseal. This promise that there is no any excessive accumulation if gas in the battery.·Heavy Duty GridsThe grids are made by heavy duty lead calcium tin alloy. This provides: Safety margin of performance condition, Excellent recovery capacity from deep discharge, Extra service life in either cycle or float usage, Low self-discharge when it is not working.·Cycle Service life of BatteryDesigned for more than 1200 times of charge/discharge cycle. The actual times will depend on the Depth of Discharge(D.O.D).·Float Service life of batteryDesigned?for float life of 5 years at 20°C(68°F).·Operation in any positionBecause SunStone batteries are sealed and all the acid is absorbed in the special separators, these batteries can be operated in both vertical and horizontal position.·Wide Operation Temperature RangeSunStone batteries can be used in wide temperature range from -35°C to 45°C.·Available in flame retardant ABS material for the battery case V0SunStone batteries cases can be made by flame retardant material V0. It depends on the requirement of customer.FunctionsUPS, Emergency Lighting, Solar Panel / Inverter, Wind Turbine, Fire Alarm & Security, Broadband, Electric powered vehicles, Electric powered toys, Vacuum cleaners, Medical Equipments, Goof cars and buggies, Wheel chairs, PVs, solar systems, control systems, power systems, wind energy systems, telecommunication /communication systems & etc.Our Factory?Packaging & Shipping?Trade termsFOB CIF EXW CFRPayment termsT/T,irrevocable L/C at sight,Western UnionDelivery time25- 30 daysPacking ?Carton+PalletShippingBy sea?Certifications??Advantages1. The battery is full of power when it’s out of factory, no need to use liquid charge;2. no memory, no need to discharge battery use, suitable for circuit design;3. by high partition, adsorption and strong;4. there is no flowing liquid (poor liquid), does not leak acid and free Upside down,5. comply with environmental requirements, ease of use,6. the use of lead-calcium alloys, battery self-discharge is very low,7. easy storage, less maintenance;8. using ABS plastic shell and valve technology for safe use.Cautions1.Don’t near the hot source and don’t under the sunshine2.Don’t charge in the sealed container.3.No short circuit. It should be addition charge if you don’t use, and single charge per three months, to avoid irreversible sulfating. The battery should be changed when the battery jar broken or the electrolyte omitted, to avoid acid in the space of acid gas.5.You should be careful and regular check when use the battery. To avoid the battery don’t work. You should change the battery if the capacity is not full or has been damage, especially after one year using.6.Don’t put the battery in the fire, or it will explode.7.Please use cotton cloth to clean, if the battery is broken down and leak electrolyte. Please wash your skin when touch the electrolyte8.Don’t clean the battery by using the organic solution. (e.g. petrol)
