The real green power supplyIts not including Sb and CD elements that harmful to environment. Even when the box broken the liquid wouldn't come out. Increase the batteries environment safety.2. The lowest internal resistanceUsed special construction. Down the resistance to the lowest and fast charging that take within 40 minutes can charge over 95% capacity. Good performance at high rate power start. High output voltage stable and peak power high.3. Low self-dischargeThis series batteries use high-class raw materials and adopt advanced technical and strict quality management control to make sure batteries have lowest self-discharge rate. Shelf life over 2 years under room temperature still can use after charge.4. Long life designThis series batteries used special prescription and process design. Not only have high specific energy also have long life. Designed over 8 years life even? Over 1200 times 50% deep discharge cycle.5. Excellent PSOC (partial state of charge) recovery performanceThis series batteries after discharged to 0 voltage and connect the positive pole and negative pole for 24 hours then full recharge again. Do the discharge to 0 voltage again and connect positive and negative pole again. After 5 times like this can recovery the capacity back to over 90%.6. Wild operational temperature rangeThis series batteries can operation between -40 degrees Celsius~65 degrees Celsius. Fit for boreal countries.
