12V 6A Car Battery Charger with Auto Cut-Off — Also for Bike & Inverter
Samco Battery has built SMPS chargers in Delhi since 2000. This car battery charger — equally at home on bike and inverter batteries — monitors your battery continuously and stops the moment voltage reaches 14.6V — a charging/absorption voltage used for many 12V lead-acid batteries. The automatic 14.6V cut-off is designed to stop charging when the battery reaches the cut-off voltage, making overnight charging more convenient. Price: ₹1,998 all taxes included. Free shipping to every city, town, and village across India.
The 12V 6 Amp Smart Battery Charger with Auto Cut-Off by Samco Battery (Delhi) is a fully automatic SMPS charger that stops at exactly 14.6V when your battery is full, helping prevent overcharging. It charges 12V lead-acid, SMF, VRLA and GEL batteries from 4Ah to 120Ah, depending on battery type and charging application — ideal for 35Ah–100Ah car batteries, and also used on bike, inverter, tractor, UPS and e-rickshaw batteries. Priced at ₹1,998 all taxes included with free shipping to 19,000+ pin codes across India.

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. The automatic cut-off makes overnight charging more convenient.
SMPS Smart Charger vs Old Transformer Charger
How this charger compares to older transformer-type chargers still widely sold in India:
| Feature | SMPS Smart Charger (This) | Old Transformer Charger |
|---|---|---|
| Auto cut-off at full charge | ✅ Yes — stops at 14.6V | ❌ Typically not — charging continues until unplugged |
| Overcharge protection | Automatic 14.6V cut-off | Typically none — manual disconnection required |
| Energy efficiency | High-efficiency SMPS design | Lower on typical transformer designs |
| Weight | Lightweight | Heavier on typical transformer designs |
| Running temperature | Cool | Hot |
| Overnight charging | Automatic cut-off provides added convenience | Requires manual monitoring |
| Battery-life impact | Helps reduce overcharging when properly used | Overcharging risk if left connected |

Frequently Asked Questions
Does this charger cut off automatically when the battery is full?
Yes. The charger automatically stops at 14.6V — a charging/absorption voltage used for many 12V lead-acid batteries — so charging stops without manual monitoring.
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 helps prevent charging beyond that point.
Which batteries is it compatible with?
12V lead-acid batteries from 4Ah to 120Ah, depending on battery type and charging application — car, bike, inverter, tractor, generator, UPS, AMF panel, e-rickshaw, solar, marine and industrial. Ideal for 35Ah–100Ah car batteries. 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?

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, plug in and leave for several hours. 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.
