{"product_id":"12v-lead-acid-battery-1-3ah","title":"12V Lead Acid Battery 1.3Ah","description":"\u003cp\u003eThe Sealed Lead Calcium Maintenance-Free Battery represents a reliable and cost-effective rechargeable solution. Distinguished by its unique features, this valve-regulated, sealed battery employs glass-mat technology to securely contain the acid, eliminating the need for refilling and ensuring leakproof operation. This maintenance-free battery is designed for low self-discharge, extended service life, and optimal performance when charged using a constant voltage method.\u003c\/p\u003e\n\u003ch2\u003eConstant Voltage Charging\u003c\/h2\u003e\n\u003cp\u003eCharging through a constant voltage approach is the preferred and widely adopted technique for battery charging. The charger voltage should be maintained within a specific range while utilising a mechanism to limit the initial current to below 0.3C. This initial current limitation can be achieved through a constant-current regulator, a well-designed output voltage from the power transformer, or by adjusting the overall impedance of the circuit, such as incorporating a current regulating resistor. As the charging process progresses, the current will naturally diminish during the final charging phase. Constant voltage charger circuits typically comprise transformers, transistors, silicon diodes, and ICs to facilitate these functions.\u003c\/p\u003e\n\u003ch2\u003eConstant Current Charging\u003c\/h2\u003e\n\u003cp\u003eThis method is advantageous for providing supplementary charging to multiple batteries connected in series during storage; however, strict control over charging time is essential. Continuing to charge at the same rate after the battery has reached full capacity can lead to excessive voltage, water decomposition, heat generation, and potential severe overcharging, which could seriously damage the battery. To maximize longevity, frequent use of constant current charging for refreshing batteries is not advisable.\u003c\/p\u003e\n\u003cp\u003eTake advantage of free shipping on orders exceeding Rs. 500 and earn RC Coins with each purchase.
