12V 1.3 Ah Lead Acid Battery The sealed Lead Calcium Maintenance-Free Battery is an advanced and economical rechargeable battery. It has several properties different from other types of batteries maintenance Free - As it is valve-regulated, sealed and glass-mat is utilized, acid is trapped inside. So, refilling is not needed and is leakproof. Explore the 12-volt battery price at Iotcart, This maintenance-free battery offers low self-discharge, long service life, and efficient performance with a constant voltage charging method. Constant Voltage Charging Charging at constant voltage is the most suitable and commonly used method for charging batteries. The charger voltage must be stabilized in a narrow range and with a device to suppress the initial current to less than 0.3C. The initial current limitation can be accomplished by a constant-current regulator, a properly designed output voltage from the power transformer, or by creating the overall impedance of the circuit (such as using a current regulating resistor). During the final stage of charge, the current decreases automatically. Show constant voltage charger circuits provided with constant voltage functions, composed of transformers, transistors, silicon diodes, IC’s etc. Constant Current Charging It is an effective method for a supplementary charge of many batteries simultaneously in series during storage but the charging time must be strictly controlled. It is because if the charging is continued at the same rate for an extended period of time after the battery has reached a fully charged state, battery voltage rises excessively, water decomposes, heat is generated, and a severe overcharge may occur resulting in heavy damage to the battery. For the longest life, it is not recommended to repeatedly use constant current charging for refreshing batteries. Enjoy free shipping on orders above Rs. 500 and earn RC Coins on every purchase.
