Use and maintenance: Never charge the battery in a sealed container Never disassemble the battery Never short-circuit battery terminals Never incinerate batteries. for they may explode Do not press and/or bend the terminals. or overheat them Do not mix old and new batteries together, neither use batteries of different types or brands Do not dispose of with household waste Be sure to use the specified charger for battery, and follow the charging instructions correctly Be sure to charge the batteries between the temperatures OoC/32oF to 45oC/113oF Be sure to position batteries securely, protecting them from abnormal shocks and /or vibration Be sure to keep sufficient space between batteries for ventilation (where possible>10mm) Be sure to install batteries in a cool and well ventilated place. The surrounding temperature must remain between -20oC/4oF to 40oC/104oF during storage

Question answer: Q: What's the capacity of the battery? A: The capacity of the VRLA battery means that when the battery is full charged and discharge at some condition to the stated end voltage. the capacity is released out, the unit is Ah For example when the battery discharges at l A current tor l hour, that's the 1 Ah capacity, if the battery discharges at 4A current for 3hours to the end voltage, the released capacity is 12AH
Q : What is EPV (Cut-Off Voltage/End Point Voltage)? A:EPV IS the battery end load voltage in the condition of discharge, Many kinds of standards rule EPV definitely in different discharge rates and temperatures.EPV is different according to different discharge rates: it is low when discharge in high current, contrarily, it is high when discharge in low current.
Q : What is the self-discharge rate of batteries? A: The self-discharge. also known as charge retention capacity that means when it is in open circuit state, the maintain ability of battery's storage electricity under certain environmental conditions. During storage time. The rate of capacity loss is called self discharge rate. It is mainly affected by the manufacture technology, materials, storage conditions and other factors, which is an important parameter to measure the battery's performance.
Q: What is discharge hour rate? A:Discharge hour rate mean the discharge capacity will decrease according to increase of discharge current under condition that the active substance quantity keep unchanged. So the discharge rate should be specified when scale the discharge capacity, Discharge rate include hour rate and current rate hour rate Q: Why the batteries need to be stored for a certain time before delivery? A: The storage capability is an important parameter for checking the stability of general capability .After a certain period storage, the variety of capacity and inner resistance is allowed. And the storage can level off the electrochemistry performance of inner component, so that we can know the extent of self-discharge capability . then pick out the batteries with short circuit ( caused by fast dropping of OCV) and micro short circuit. so the battery quality can be ensured
Q ; Why the battery cannot be charged(fully charged)? A: After using tor a few months, the battery can not be charged because the occur of Lead sulfate (PbS04) sulfation as it is commonly called. Generally speaking, sulfation is the prime cause of battery failure and loss of capacity especially sulfation is a natural occurrence in all lea d/acid batteries including sealed, gel-cell and recumbent batteries it the prime cause of early battery failure and is when the sultur in the sulturic acid to forms sulfur crystals attach to the lead plates and then act as an "insulation" keeping the battery from accepting a charge.Typical chargers and even "smart or automatic chargers' can not overcome this phenomena and thus the battery is discarded as "not being able to hold a charge' Sulfation occur far more readily in hot climates Sulfation can occur in brand new batteries in as short of time period ofa few weeks or a few months.
Q: How to avoid the plate sulfation? A:1.Using an extended charge, known as an equalization charge to slow-down the rate of sulfation 2 .Avoid low cutoff voltage discharges 3. Recharge immediately after discharge 4. Completely charged before using 5. Please shelve the battery after it s fully charged
