Label: Question: There are too many terms in the selection of valve-regulated sealed maintenance-free lead-acid batteries, can you give a list for reference? Answer: There are many users of valve-regulated sealed maintenance-free lead-acid batteries in the use and battery selection There are many doubts, because there are many terms involved, if you don’t understand it, errors may occur in the selection process, which will not only affect the use effect, but also the cost of replacement is very high. As a manufacturer, we are very happy to answer this question for you. Below, I have selected some of the more commonly used terms, I hope to help you: overdischarge (overdischarge): continue to discharge after being lower than the prescribed termination voltage of the lead-acid battery. Recovery charge (recovercharge): prepare for the next discharge, Charge the discharged lead-acid battery to restore its capacity. Overcharge: the charge that continues after reaching the fully charged state. Full discharge: discharge the lead-acid battery to the specified termination voltage according to the specified discharge current Maximum discharge current (maximumdischargecurrent): the maximum current that the battery can discharge without causing deformation, abnormal appearance, or fuse of the pole. Self-discharge: no current is provided to the outside, and the internal loss of current capacity is reduced. Rated Voltage (nominalvoltage): indicates the standard voltage used when the voltage of a lead-acid battery is used. Generally, it is a theoretical value slightly lower than the initial voltage. Nominal capacity (nominalcapacity): Under the conditions of temperature, discharge current and termination voltage specified in the standard, the battery The actual capacity of the ampere-hour electricity that can be provided by the manufacturer after it is fully charged (actualcapacity): the lead-acid battery actually has the capacity to discharge at a certain hourly rate, expressed as Ah. Cycles service system (cycles service system): take the discharge after charging as a It is used in cycles. Hourrate: The time rate for discharging with a constant current to the set end voltage. The capacity of the battery is generally expressed in hours. Tricklecharge: To compensate for the battery The self-discharge of the battery is continuously charged with a small current when it is separated from the load. Floating charge: The lead-acid battery and the load are connected in parallel to the rectifier charger, and the charger continuously applies a certain voltage to the battery The charging method that maintains the charged state. In the event of a power outage or load change, the battery can directly and uninterruptedly provide power to the load. Constant voltage charge: A charging method that maintains a constant voltage between terminals. Constant current charge: Use a constant The method of current charging. Standby (stand-byuse): Floating charge and trickle continuous charge that have been in the charging state for emergency use. Internal resistance: The sum of the battery’s internal electrolyte and electrode group resistance Cut-off voltage of discharge: according to the size of the discharge current and the type of battery, the terminal voltage at which the discharge should theoretically stop the discharge is set according to the size of the discharge current and the battery type. Capacity conservation performance (capacityconservationper formance): After the lead-acid battery is fully charged, it can be stored in an open circuit state for a period of time under certain conditions. Internal short-circuit: in the pole group inside a single lead-acid battery, between the positive and negative plates The phenomenon of short circuit.
