12V 24V 10 Amp Automatic SMPS Battery Charger — Inverter, DG Set, Car & Truck

Boost mode delivers full current (up to 10A) to charge a depleted battery as fast as possible — use it when the battery is discharged and you need it back at 100% quickly. Float mode delivers a low trickle current that holds the battery at a regulated float voltage rather than pushing charge into a full battery — suited to DG sets, inverters, gensets and vehicles kept on standby. You select between the two manually using the front-panel switch — the charger does not switch modes on its own.

The current reading on the digital ammeter drops steadily as the battery charges, falling to near 0A as it approaches a charged state. Mode selection is manual: you choose Boost or Float on the front-panel switch. For standby maintenance, switch to Float according to the battery manufacturer's instructions and check the battery periodically while charging.

No manual setting needed. The charger detects automatically, on connection, whether the battery is 12V or 24V — there is no selector switch to set. That removes the voltage-selection step — useful in mixed workshops running both 12V and 24V batteries.

Works with 12V and 24V lead-acid batteries — tubular, flat-plate, SMF and VRLA (AGM and GEL). Practical range is roughly 7Ah sealed batteries at 2–3A up to ~220Ah inverter banks at 8–10A. Used with Exide, Luminous, Amaron, Su-Kam and other common Indian brands. The variable knob lets you match the current to the battery size.

Yes — this is one of the most common uses. In Float mode, the charger holds the DG set's 12V or 24V starter battery on a regulated float voltage, so it is not sitting flat when mains power fails. Used in factories, hospitals, housing societies and anywhere generator start time matters.

Yes. Boost mode charges a discharged tubular or SMF inverter battery (Exide, Luminous, Amaron) back to full. Selecting Float then holds it at a regulated float voltage between cuts, which avoids the gassing and water loss that overcharging causes. Works with 100Ah to 220Ah tubular and sealed batteries — expect around 17 hours for a flat 150Ah bank at 10A.

The knob adjusts charging current in 6 steps from 0 to 10 Amps. Use lower current (2–4A) for small or sensitive batteries like VRLA, GEL and SMF; use higher current (8–10A) for large 150–200Ah tubular banks — which is still an overnight charge, not a quick one. The digital ammeter shows live current so you always know exactly what is happening.

Yes. The wide 160–280V AC input covers the range seen on much of India's grid — rural supply that can drop to 160V at peak hours or rise above 250V at night. SMPS regulation holds the output steady across that input range.

Haan — yeh charger Exide InvaMaster, Luminous Red Charge, Amaron Inverter, Su-Kam Shakti aur jaisi common tubular, SMF aur VRLA batteries ke liye kaam karta hai. 100Ah ho ya 220Ah, 12V ho ya 24V — variable knob se current set karo. Boost mode se charge karo, Float mode se maintain karo. 150Ah battery 10A par lagbhag 17 ghante leti hai.

Inverter battery backup zyada tar do wajah se kam hota hai: ek, battery poori tarah charge nahi ho paati kyunki purana charger sahi voltage nahi deta. Dusra, battery over-charge hoti hai jisse plates kharab hote hain. Is charger ka Boost mode battery ko poora charge karta hai aur Float mode usse regulated float voltage par maintain karta hai. Battery full hone par current apne aap taper ho jaati hai, isliye overcharging wali damage nahi hoti.

Yes — significantly. A basic fixed-output charger may keep supplying current after the battery approaches full charge, which causes gassing, water loss and plate damage — a common cause of early inverter-battery failure. An SMPS charger tapers current toward zero instead. It also has Float mode for standby maintenance, variable current across battery sizes, auto 12V/24V detection and a digital ammeter so you can see what is happening.

As an estimate, a deeply discharged 150Ah tubular inverter battery takes roughly 17–18 hours at 10A. The formula is: Capacity (Ah) ÷ Current (A) × 1.15 (efficiency factor) = charging time in hours. So 150 ÷ 10 × 1.15 ≈ 17.25 hours. For a 100Ah battery at 10A: approximately 11–12 hours. For a 200Ah battery at 10A: approximately 23 hours. The digital ammeter shows current dropping in real time — as the current falls toward near 0A, the battery is approaching a charged state. These are estimates from a deeply discharged battery; actual time varies with battery condition, state of charge, temperature and current taper.

A battery charger charges a depleted battery back to full — typically using high current (Boost mode) for a defined period. A battery maintainer (also called a trickle charger or float charger) holds an already-full battery at float voltage by supplying only the small current needed to offset natural self-discharge. This charger does both, with the two modes selected manually on the front-panel switch: Boost to charge a depleted battery, Float to hold it. This is why it is called a Float Cum Boost Charger (FCBC) — it is a charger and a maintainer in one unit.

For a home inverter battery, look for automatic current taper and a float mode. This SMPS Float Cum Boost Charger tapers current as the battery approaches a charged state, falling to near 0A. Use Boost mode to recharge a depleted Exide, Luminous or Amaron tubular battery, then select Float on the switch to hold it. Works with 100Ah to 220Ah inverter batteries — tubular, flat-plate, SMF and VRLA (AGM and GEL). Samco Battery has designed and manufactured automatic battery chargers from Delhi since 2000 and ships pan-India with free delivery.

Yes. The charger is brand-agnostic — what matters is the battery's voltage and capacity, not its badge. It is used with Exide InvaMaster, Exide Magic, Luminous Red Charge, Luminous Eco Volt, Amaron Inverter, Amaron Quanta, Su-Kam Shakti and other 12V and 24V lead-acid batteries. No brand-specific setting is needed; set the current on the knob to suit the capacity.

Yes. It auto-detects whether the connected battery is 12V (car, SUV, auto rickshaw) or 24V (truck, bus, e-rickshaw). For a 35–100Ah car battery, set the knob to 4–8A — roughly 4 hours for a flat 35Ah battery at 10A. For a 24V truck starter battery the charger detects 24V and you can use the full 10A. One unit covers both, so a mixed fleet does not need two chargers. Forklift and stacker traction packs are a different job — see our 24V 10A stacker charger.

The price is ₹4,764 — all taxes included, with free delivery across India.
