02 — Why automatic
Why choose an automatic SMPS car battery charger?
What “automatic” means here: the charger tapers the current as the battery fills and stops charging when the battery reaches approximately 14.6V, so you never set a dial or watch a clock. It does not mean every battery is suitable — follow the charging voltage and current your battery manufacturer specifies, and check the capacity and chemistry notes above before connecting.
Stops at 14.6V by itself
An old transformer charger pushes a fixed current until you unplug it — leave it connected too long and you can overcharge the battery. This one monitors voltage, tapers the current and stops charging at approximately 14.6V on its own.
You can see what it's doing
The digital display shows output voltage and charging current in real time. A weak or failing car battery shows itself within minutes — before it strands you at 7 AM on a Monday.
Three-way protection
Overload, short-circuit and reverse-polarity protection stay active throughout. Connect the clamps the wrong way round and the charger protects itself — and your battery.
Built for Indian mains
The 160–280V input range is designed to accommodate a wide range of Indian mains-voltage conditions.
03 — Fitment
Will this car battery charger fit my vehicle?
If it has a 12-volt lead-acid battery between 35Ah and 100Ah — which covers most cars, SUVs, tractors and generator sets sold in India — the answer is yes. Check the Ah printed on your battery, then match it below.
What this charger fits
- 12V flooded, SMF and VRLA/AGM lead-acid batteries
- Car, SUV, jeep, truck and tractor starter batteries
- Home inverter, UPS and DG-set batteries
What it is not for
- Lithium-ion and LiFePO₄ packs
- GEL batteries, unless the maker specifies 14.6V absorption
- Tubular inverter banks above 120Ah
- Batteries below 35Ah — use the 3A model instead
- 6V batteries, 24V batteries or 24V series banks
04 — Charging time
Illustrative charging-time estimates at 6A
The following are approximate examples from a deeply discharged battery. Actual charging time varies with depth of discharge, battery age, condition, temperature and charging characteristics.
| Battery (popular examples in India) | Typical capacity | Time at 6A |
|---|---|---|
| Maruti Alto, WagonR, S-Presso · Hyundai i10 · Renault Kwid | 35–40Ah | ~7–8 hours |
| Maruti Swift, Baleno, Dzire · Hyundai i20, Venue · Tata Nexon, Punch · Honda Amaze | 40–50Ah | ~8–10 hours |
| Hyundai Creta, Verna · Tata Harrier · Mahindra XUV300 · Honda City | 50–60Ah | ~10–12 hours |
| Mahindra Bolero, Scorpio, Thar · Toyota Innova · older SUVs & jeeps | 65–80Ah | ~13–16 hours |
| Tractors (Mahindra, Swaraj, Eicher) & DG sets | 65–100Ah | ~13–20 hours |
| Home inverter / UPS (SMF or VRLA) | up to 120Ah | up to ~24 hours |
Quick formula: battery Ah × 1.2 ÷ 6 gives an approximate number of hours from a deep discharge — a 45Ah battery ≈ 45 × 1.2 ÷ 6 ≈ 9 hours.

How to charge a car battery at home — 3 steps
Connect the clamps
Switch off the ignition and all accessories. Red clamp to the positive terminal (+), black clamp to the negative (–). Do not plug into the mains yet. No need to remove the battery from the car.
Switch on the mains
The display lights up and shows the battery's present voltage. A flat car battery may read 11–12V and pull close to 6A. The current then tapers down automatically as the battery fills.
It stops on its own
Automatic charging control stops charging when the battery reaches approximately 14.6V. Switch off the mains, remove the clamps (black first), and your battery is ready to crank.
06 — Use cases
What people across India charge with a 12V 6A charger
Car & hatchback batteries
The core job. 35Ah to 65Ah starter batteries in hatchbacks and sedans — especially cars that sit unused for weeks and then crank slowly. Top the charge up while the car sits parked — the charging-time estimates above show what to expect.
SUV, taxi & light commercial
65Ah to 100Ah batteries in SUVs, taxis and small commercial vehicles. At the top of that range 6A is below the 10% guideline, so allow longer — the charger stops automatically at approximately 14.6V.
Tractor & farm equipment
Tractor and pump-set batteries idle between seasons and sulphate quietly. Automatic charging control means less clock-watching during seasonal top-ups.
Small inverter & UPS batteries
Up to about 120Ah on suitable types. Larger tubular banks want the 12V 15A SMPS charger or the 12V 20A FCBC.
Bike, scooter & CCTV batteries
Below 35Ah, a 6A charger is more than the battery needs — the 12V 3A bike battery charger at ₹993 is the right tool for bike, scooter and CCTV batteries.
Garages & service bays
A bench unit for routine top-ups that pays for itself in saved battery warranties. For manual control across a wider range, the 12V 10A variable charger spans 7Ah to 220Ah.

08 — Questions
Car battery charger FAQs — answered by the manufacturer
Will it overcharge my battery if left connected?
Automatic charging control stops charging when the battery reaches approximately 14.6V. After cut-off, the display shows the battery's resting voltage, and the overload, short-circuit and reverse-polarity protection stay live while the unit remains plugged in. Best practice is still to switch off the mains once the battery is full, to charge where you can check on the unit periodically, and to follow your battery manufacturer's guidance.
क्या COD (कैश ऑन डिलिवरी) उपलब्ध है?
हाँ। इस कार बैटरी चार्जर को पूरे भारत में COD पर मंगाया जा सकता है — WhatsApp या 99539 35912 पर ऑर्डर करें और डिलीवरी पर नकद या UPI से भुगतान करें। हर ऑर्डर के साथ GST invoice आता है, डिलीवरी 3–7 कार्य दिवस में फ्री है, और दिल्ली NCR में डिलीवरी सबसे तेज़।
Can I charge the battery without removing it from the car?
Yes — switch off the ignition and remove the key, connect red to positive and black to negative, then plug in. If your car manual advises disconnecting, remove only the negative terminal first. Reverse-polarity protection covers accidental wrong connections.
My car battery is completely dead. Can this charger revive it?
A deeply discharged battery may recover if it is otherwise healthy and undamaged — never charge one that is cracked, leaking, swollen or frozen, and always charge in a ventilated spot. Connect, switch on, and watch the display voltage climb over several hours. A battery with a failed cell or severe sulphation will not accept a charge; no charger can fix that.
Why does my car battery keep discharging when the car is parked?
Three common reasons in India: short runs that never fully recharge the battery, parasitic drain from alarms and accessories while parked, and heat — Delhi summers are hard on batteries. A regular top-up with an automatic charger can help maintain the battery's state of charge and reduce avoidable no-start situations.
How fast is delivery — and can I collect in person?
Every unit ships free from our Kashmere Gate unit in Delhi — 3–7 working days to 19,000+ pincodes across India, COD, UPI and bank transfer accepted nationwide.

How is the 6A different from the 3A, 10A, 15A and 30A models?
The 3A suits small bike, scooter and CCTV cells (4Ah–30Ah); this 6A is the all-rounder for cars, SUVs, tractors and small inverters (35Ah–100Ah); the 10A variable adds manual control across 7Ah–220Ah; the 15A and 30A serve large inverter banks. Full prices are in the comparison table below — or WhatsApp us your battery's Ah and we'll match it in minutes.
