Key Features of the 12V 10A SMPS Battery Charger
Variable current control, live digital ammeter, Boost and Float modes — features normally found only in chargers costing ₹5,000 or more, available here at ₹2,951.
Digital Ammeter — Live Display
Large digital meter shows live charging current. Watch amps fall as battery fills — no guesswork, no damage. You know exactly when charging is complete.
Manual Boost / Float Switch
BOOST for fast charging a discharged battery. FLOAT to safely maintain a full battery for weeks without overcharging. One switch — you control the mode.
Automatic Battery Maintainer
Current tapers to near-zero as battery reaches full charge. Safe to leave connected to your inverter or DG set battery 24×7 without supervision.
High Frequency SMPS Technology
Compact, light, cool-running. Far more efficient than old heavy transformer chargers — no overheating on long charge cycles, longer service life.
Full Protection Built In
Overload, short circuit and reverse polarity protection. Safe for permanent connection. No damage if clamps are accidentally reversed or shorted.
Wide Input: 160–280V AC
Handles India's fluctuating grid voltage reliably — rural low-voltage supply, city mains and generator power. No stabiliser required.
Revives Batteries Others Refuse
Automatic chargers display "bad battery" on flat cells and refuse to charge. This charger starts at 1–2A and slowly recovers voltage — reviving batteries written off as dead.
Comparison note: At ₹2,951, this SMPS variable charger sits between basic transformer chargers (₹600–1,500) and expensive fully automatic chargers (₹3,000–10,000), while outperforming both — offering variable control, dead battery recovery, and Boost/Float switching that neither alternative provides.

How to Charge an Inverter, Car or Tractor Battery — Step by Step
Connect Clamps
Red (+) to positive, black (−) to negative terminal. Reverse polarity protection prevents damage if clamps are accidentally switched.Set Current Knob
Turn 0–10A dial to 10% of battery Ah: 10A for 100Ah, 5A for 50Ah, 1A for 10Ah motorcycle. 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 battery fills, resistance rises and current drops naturally — no manual intervention needed.Charging Done
Ammeter near-zero means battery is fully charged. Charger enters maintainer mode automatically. Safe to leave connected indefinitely.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 any 12V lead-acid battery from 7Ah (motorcycle) to 220Ah (large tubular inverter). 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 best for inverter batteries. The Samco 12V 10A SMPS Charger at ₹2,951 charges 100–200Ah tubular batteries at the correct 10% Ah rate, maintains charge safely on Float mode, and can be left connected permanently without overcharging. 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 lower maintenance voltage to keep a fully charged battery topped off indefinitely without overcharging. Toggle manually with the front panel switch. Essential for DG set starter batteries and inverter batteries kept on permanent connection.
Can this charger revive a completely dead or flat battery?
Yes. Switch to BOOST mode and set the current knob to 1–2A. The charger slowly trickles current and recovers battery voltage. Once voltage rises, gradually increase current. This revives batteries that fully automatic chargers display as "bad battery" and refuse to 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 — for only ₹2,951.
Which battery types are compatible with this 12V charger?
All 12V lead-acid types: flat-plate, tubular, SMF (sealed maintenance-free), VRLA, gel and AGM. 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. The Float mode keeps the tubular battery topped up safely during long power cuts without overcharging the plates. Compatible with all tubular, flat-plate and SMF inverter batteries from Exide, Luminous, Amaron, Microtek and Okaya. Price: ₹2,951, free shipping all India.
What is the warranty?
6 months warranty from Samco Battery, Delhi. Contact +91-9953935912 or hi@samcobattery.in. Full Warranty & Return Policy →

Free shipping, 2–7 business days.
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. When the ammeter reads near-zero, the battery is fully charged. Works for all Indian car batteries — Maruti, Hyundai, Tata, Honda, Toyota, Mahindra — from 35Ah to 100Ah. Price ₹2,951, ships from Delhi.
