Why Choose a Smart Battery Charger with Auto Cut-Off?
An ordinary transformer charger delivers a fixed current and does not stop — even after the battery is full. This causes overcharging, sulphation of battery plates, overheating, and premature battery failure. This charger uses high-frequency SMPS technology to monitor voltage continuously and cut off at the 14.6V set point. The automatic cut-off ends the charge without manual intervention.

How to Charge a Battery Using This Charger
Follow these 6 steps to charge a 12V lead-acid, SMF or VRLA battery. GEL batteries often specify a lower absorption voltage than 14.6V — check the battery manufacturer’s figure before charging one. The charger manages the cycle itself automatically.
1Ensure Battery is Disconnected from Any Load
Before connecting the charger, make sure the battery is disconnected from the vehicle or appliance it powers. For car batteries, turn off the ignition and all accessories.
2Identify Battery Polarity
Locate the positive (+) and negative (−) terminals on your battery. The positive terminal is usually marked with a + sign and is often larger. Incorrect polarity will trip the reverse-polarity protection.
3Connect Red Clamp to Positive (+) Terminal
Clip the red clamp firmly onto the battery's positive (+) terminal. Ensure it makes solid metal-to-metal contact and won't slip off during charging.
4Connect Black Clamp to Negative (−) Terminal
Clip the black clamp firmly onto the battery's negative (−) terminal. Ensure both clamps are secure before plugging into the mains.
5Plug Into Mains Socket (160–280V AC)
Connect the charger to a standard 160–280V AC, 50Hz mains socket. The digital display will light up immediately, showing the battery's current voltage and the charging current in amps. Charging begins automatically.
6Charger Auto Stops at 14.6V — Charge Cycle Ends
As the battery charges, the display voltage rises and the current tapers down. When the battery reaches 14.6V — a charging/absorption voltage used for many 12V lead-acid batteries — the charger stops automatically. The display will show 14.6V and near-zero amps. Once the charger reaches its cut-off point, charging stops automatically.
Charging time guide: A fully discharged 35Ah car battery takes approximately 7 hours at 6A. A 45Ah battery takes approximately 9 hours. A 100Ah inverter battery takes approximately 20 hours. The charger cuts off automatically at the set voltage. Follow the charging instructions supplied by your battery manufacturer, and check on the charger periodically.

Frequently Asked Questions
Does this charger cut off automatically at the end of a charge?
Yes. The charger stops automatically at its 14.6V set cut-off — a charging/absorption voltage used for many 12V lead-acid batteries. Periodic checking is still recommended, and the battery manufacturer’s charging instructions should be followed.
What is 14.6V and why does the charger stop there?
14.6V is a charging/absorption voltage used for many 12V lead-acid batteries. The correct charging voltage varies by battery type and manufacturer — GEL batteries in particular often specify a lower figure — so always follow the battery manufacturer’s charging specification. Sustained charging above a battery’s specified voltage can cause electrolyte loss, plate sulphation and overheating; the 14.6V cut-off helps prevent charging past that set point.
Which batteries is it compatible with?
Best suited to 35Ah–100Ah 12V car batteries. It also suits smaller 4Ah–30Ah batteries where a 6A rate is appropriate, and up to 120Ah on suitable types and applications — check the charging current your battery manufacturer recommends. Flooded, SMF and VRLA (AGM) types are covered; GEL batteries often specify a lower absorption voltage than 14.6V, so check that figure before charging one. For large tubular inverter banks, use the 12V 20A charger instead.
How long does it take to charge a car battery?
At 6A: a 35Ah hatchback battery (Maruti, Hyundai) takes ~7 hours; a 45Ah sedan ~9 hours; a 100Ah inverter or truck battery ~20 hours. These are estimates only — actual time varies with depth of discharge, battery age and condition, temperature, and how much current the battery accepts.
Does it work in areas with voltage fluctuations?
Yes. The wide 160–280V AC input handles the voltage fluctuations common in rural India, small towns, and industrial areas.
Is dealer or wholesale pricing available?
Yes. Contact us on WhatsApp at +91 99539 35912 for dealer and bulk pricing.

My car or bike battery is completely dead and not starting. Can this charger revive it?
A deeply discharged battery may be recoverable if the battery is otherwise healthy — connect it, switch on, and allow several hours, checking on the charger periodically. The display will show voltage slowly rising. However, a battery with a failed cell, severe sulphation, physical damage or other internal faults may not accept a normal charge.
