Key Features of the 12V 10A SMPS Battery Charger
Variable current control, live digital ammeter, Boost and Float modes — features more often seen on higher-priced chargers, available here at ₹3,234.
Digital Ammeter — Live Display
Large digital meter shows live charging current. As charging progresses the current may decrease; use the battery manufacturer’s charging specification to determine when charging is complete.
Manual Boost / Float Switch
BOOST for fast charging a discharged battery. FLOAT is suitable for long-term maintenance charging of a fully charged battery. One switch — you control the mode.
Automatic Battery Maintainer
Current tapers to near-zero as battery reaches full charge. Suitable for inverter and DG set batteries where continuous maintenance charging is required.
High Frequency SMPS Technology
Compact, light, cool-running. High-frequency switching design — lighter and cooler-running than typical transformer chargers on long charge cycles.
Full Protection Built In
Overload, short-circuit and reverse-polarity protection helps protect the charger against incorrect connections and short circuits. Suitable for long-term maintenance charging when used in Float mode.
Wide Input: 160–280V AC
The 160–280V AC input range covers the voltage fluctuation common on rural supply, city mains and generator power, so a separate stabiliser is not usually needed.
Can Help Start Charging Some Deeply Discharged Batteries
Automatic chargers may display "bad battery" on deeply discharged cells and refuse to start. This charger can initiate charging at 1–2A on some deeply discharged batteries that automatic chargers may reject.
Comparison note: At ₹3,234, this SMPS variable charger sits between basic transformer chargers (₹600–1,500) and expensive fully automatic chargers (₹3,000–10,000), and offers a combination of variable current control, digital current display and Boost/Float switching that may not be available on basic transformer chargers.

How to Charge an Inverter, Car or Tractor Battery — Step by Step
Connect Clamps
Red (+) to positive, black (−) to negative terminal. Reverse-polarity protection helps protect the charger if the clamps are accidentally switched.Set Current Knob
As a typical starting guideline for suitable lead-acid batteries, set the 0–10A dial to around 10% of the battery’s Ah rating — roughly 10A for 100Ah, 5A for 50Ah, 1A for a 10Ah motorcycle battery. Always follow the charging current your battery manufacturer specifies. Start at 1–2A for deeply flat batteries.Select Boost or Float
BOOST for fast active charging of a discharged battery. FLOAT to maintain a battery already near full or in long-term storage.Watch the Ammeter
Live amps display on the digital meter. As the battery charges and its terminal voltage rises toward the charger’s set point, the current typically falls. Check on the charger periodically rather than leaving it running unattended.Charging Done
A significant reduction in charging current can indicate that the battery is approaching a charged state; verify the battery according to the manufacturer’s charging specifications. The charger then tapers to maintainer mode automatically.SMPS Battery Charger vs Transformer Charger vs Automatic — India Comparison

Frequently Asked Questions
What is a 12V 10 Amp High Frequency SMPS Battery Charger?
A 12V 10 Amp SMPS Battery Charger converts 160–280V AC mains to regulated 12V DC at up to 10A to charge 12V lead-acid batteries. The Samco Battery version adds a variable 0–10A current knob, live digital ammeter, and manual Boost/Float switch. It charges 12V lead-acid batteries from 7Ah (motorcycle) to 220Ah (large tubular inverter), with the current set to suit each battery. Sold and shipped from Delhi since 2000.
Which battery charger is best for a home inverter in India?
A variable-current SMPS charger with Float mode is well suited to inverter batteries. The Samco 12V 10A SMPS Charger at ₹3,234 charges 100–200Ah tubular batteries at a commonly used 10% Ah charging rate. Float mode is designed for long-term battery maintenance and helps reduce the risk of overcharging when the charger is used according to the battery manufacturer’s requirements. Compatible with Exide, Luminous, Amaron, Microtek, Okaya and Su-Kam batteries.
What does the Boost / Float switch do on a battery charger?
BOOST applies higher voltage for fast active charging of a discharged battery. FLOAT applies a lower maintenance voltage intended to keep a fully charged battery topped off while helping prevent overcharging. Toggle manually with the front panel switch. Useful for DG set starter batteries and inverter batteries kept on long-term maintenance charging.
Can this charger revive a completely dead or flat battery?
Often, if the battery is still serviceable. Switch to BOOST mode and set the current knob to 1–2A. The charger applies a low current and, on a serviceable battery, terminal voltage may rise as charge is restored. Once it does, increase the current gradually. This can initiate charging on some deeply discharged batteries that automatic chargers may reject. A battery with a shorted cell, severe sulphation or physical damage may not accept a normal charge.
What is the difference between an SMPS charger and a transformer charger?
An SMPS charger is compact, light, efficient and cool-running, handling 160–280V AC. A transformer charger uses a heavy iron core, runs hot and is less efficient. The Samco SMPS charger offers variable current control, Boost/Float switching and a digital ammeter that transformer chargers do not provide.
Which battery types are compatible with this 12V charger?
All 12V lead-acid types: flat-plate, tubular, SMF (sealed maintenance-free), VRLA and AGM. GEL batteries often specify a lower charging voltage, so check the figure your battery manufacturer states and set the current knob accordingly before charging one. Not compatible with lithium batteries. Charges inverter, car, truck, tractor, motorcycle, DG set, UPS, solar, forklift and marine batteries from 7Ah to 220Ah.
Which battery charger is best for Exide or Luminous tubular inverter battery?
For Exide or Luminous tubular inverter batteries (100Ah–200Ah), the Samco Battery 12V 10A SMPS Charger is ideal. Set the current knob to 10A for a 100Ah battery. Float mode is intended to keep the tubular battery topped up during long power cuts while helping reduce the risk of overcharging. Compatible with all tubular, flat-plate and SMF inverter batteries from Exide, Luminous, Amaron, Microtek and Okaya. Price: ₹3,234, free shipping all India.

How to charge a dead car battery at home in India?
To charge a dead car battery at home: connect the Samco 12V 10A charger clamps (red to +, black to −), switch to BOOST mode, set the current knob to 1–2A (start low for a deeply flat battery). The digital ammeter will show current flowing in. As voltage recovers after 30–60 minutes, increase current to 5–10A. A significant reduction in charging current can indicate the battery is approaching a charged state; verify against the battery manufacturer’s charging specifications. Suitable for common Indian car batteries — Maruti, Hyundai, Tata, Honda, Toyota, Mahindra — from 35Ah to 100Ah. Price ₹3,234, ships from Delhi.
