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 precisely 14.6V. Safe to leave connected overnight — every night.

How to Charge a Battery Using This Charger
Follow these 6 steps to safely charge any 12V lead-acid, SMF, VRLA, or GEL battery. No technical knowledge required — the charger manages the entire process 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 — Battery Is Full
As the battery charges, the display voltage rises and the current tapers down. When the battery reaches 14.6V — the correct full-charge voltage for 12V lead-acid batteries — the charger stops automatically. The display will show 14.6V and near-zero amps. The battery is fully charged and the charger is safe to remain connected indefinitely.
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 — there is no risk in leaving it overnight.

Frequently Asked Questions
Does this charger cut off automatically when the battery is full?
Yes. The charger automatically stops at 14.6V — the correct full-charge voltage for a 12V lead-acid battery — and is safe to leave connected overnight.
What is 14.6V and why does the charger stop there?
14.6V is the standard full-charge voltage for a 12V lead-acid battery (flooded, AGM, VRLA, or GEL). Charging beyond this point causes electrolyte loss, plate sulphation, and overheating. Auto cut-off at 14.6V is the safest approach.
Which batteries is it compatible with?
Any 12V lead-acid battery from 4Ah to 120Ah — car, bike, inverter, tractor, generator, UPS, AMF panel, e-rickshaw, solar, marine, and industrial. Compatible with flooded, SMF, VRLA (AGM), and GEL types.
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. Actual time depends on the starting state of discharge.
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.
Do you deliver to my city, town, or village?
Yes — ships from Delhi to 19,000+ pin codes across India via India Post Speed Post and Trackon. Delivery: approx. 2–7 business days. COD, UPI, or bank transfer.
My car or bike battery is completely dead and not starting. Can this charger revive it?
In most cases, yes. A dead battery that has fully discharged but is otherwise undamaged can be recovered — connect, plug in, and leave for several hours. The display will show voltage slowly rising. If the battery has dead cells, the display will show near-zero current after a short time, indicating it is unrecoverable.
