12V 6 Amp Smart Battery Charger with Auto Cut-Off

Yes. The charger monitors battery voltage continuously and stops at exactly 14.6V — the correct full-charge voltage for a 12V lead-acid battery. Once at 14.6V, the charging current drops to near zero and the charger enters standby. It is completely safe to leave connected overnight or for multiple days.

14.6V is the standard absorption/full-charge voltage for a 12V lead-acid battery (flooded, AGM, VRLA, or GEL). At this voltage, the battery has absorbed its maximum charge. Charging beyond 14.6V causes electrolyte loss, plate sulphation, and overheating — which is why the auto cut-off at exactly 14.6V is the safest and most battery-friendly approach.

Any 12V lead-acid battery from 4Ah to 120Ah — including car, bike, inverter, tractor, generator, UPS, AMF panel, e-rickshaw cells, solar storage, marine, and industrial batteries. Compatible with flooded, SMF, VRLA (AGM), and GEL battery types.

At 6A, a fully discharged 35Ah hatchback battery (Maruti, Hyundai) charges in approximately 7 hours. A 45Ah sedan battery takes approximately 9 hours. A 100Ah inverter or truck battery takes approximately 20 hours. The exact time depends on the starting state of discharge — a partially discharged battery will charge proportionally faster.

₹1,858 — all taxes included. Shipping is completely free to every city, town, and village across India. COD and UPI accepted. Ships from Samco Battery's Delhi store via India Post Speed Post and Trackon in approx. 2–7 business days.

Yes. The input range is 160–280V AC, 50Hz. This wide input range specifically handles the voltage fluctuations common in rural India, small towns, and industrial areas — including areas where voltage frequently drops below 200V or spikes above 240V.

A transformer charger uses a heavy iron core transformer to step down voltage and delivers a fixed, unregulated current. It does not stop when the battery is full — causing chronic overcharging, plate damage, and early battery failure. This SMPS charger uses high-frequency switching (up to 90% efficient) to deliver regulated current, monitors voltage in real time, cuts off at 14.6V, runs cool, weighs under 1 kg, and actively extends battery life.

Yes. It charges any 12V inverter battery from 4Ah to 120Ah — including Exide, Luminous, Amaron, and Okaya. The auto cut-off at 14.6V ensures the battery is never overcharged, making it ideal for overnight home use during power cuts.

Yes. It works with any 12V lead-acid battery in the 4–120Ah range — Mahindra/Swaraj tractor batteries, individual 12V cells in e-rickshaw packs, generator starter batteries, forklift cells, and all standard 12V types. The wide 160–280V input makes it reliable for rural and semi-urban use across India.

Yes — this is a fully automatic car battery charger for all 12V petrol and diesel cars. It works with every major car brand in India: Maruti Suzuki (Swift, Dzire, Baleno, Ertiga, Vitara Brezza), Hyundai (i10, i20, Creta, Venue), Tata (Nexon, Altroz, Punch, Harrier), Honda (Amaze, City), Toyota (Glanza, Urban Cruiser), Mahindra, Renault, Kia, and all others. Any 12V lead-acid or SMF car battery from 35Ah to 100Ah is compatible.

Yes — this is a reliable two-wheeler battery charger for all 12V bikes and scooters. Works with Hero Splendor, Honda Activa, Bajaj Pulsar and Avenger, TVS Apache and Jupiter, Royal Enfield (Bullet, Classic, Thunderbird), Yamaha FZ and MT, Suzuki Access and Gixxer, and all other 12V bikes, scooters, and mopeds. A fully discharged 9Ah Activa battery charges to full in approximately 2 hours at 6A.

In most cases, yes. A dead battery that has discharged fully but is otherwise undamaged can be recovered by a slow, regulated SMPS charger. Connect the charger, plug in, and leave it for several hours — the digital display will show voltage slowly rising as the battery recovers. If the battery was discharged due to lights being left on, AC use, or long parking, this charger will very likely revive it. If the battery has dead cells or is physically damaged, no charger can fix it — but this charger will tell you by showing near-zero current after a short time.

Yes — this is a fully automatic battery charger. You plug it in and walk away. Unlike a manual transformer charger which keeps pushing current until you physically unplug it, this automatic charger monitors battery voltage continuously and stops itself at 14.6V. It is also called a smart charger, auto cut-off charger, or self-regulating charger. The digital display shows real-time voltage and amps — so you can see exactly what is happening at any moment.

The price of this 12V 6A automatic battery charger is ₹1,858 — all taxes included. There are no hidden charges. Shipping is completely free across India. You can buy this battery charger online directly from Samco Battery by sending a WhatsApp message to +91 99539 35912 or calling the same number. We accept COD (cash on delivery), UPI, and bank transfer. We do not sell on Amazon or Flipkart — we ship directly from our Delhi store to keep prices fair and service fast.
