Who Buys This 12V 24V 10A SMPS Charger — And Why
From garages in Delhi to farms in Bihar, from hospitals in Chennai to fleet depots in Gujarat — here is exactly who orders this charger and what problem it solves for them.
Garage & Workshop Owners
You charge 10–20 batteries a day — cars, SUVs, trucks and e-rickshaws all mixed together. The variable 0–10A knob handles everything from a 35Ah Maruti battery to a 200Ah truck battery without changing the charger. Auto 12V/24V detection means zero risk of connecting the wrong voltage across a mixed bay. The digital ammeter shows charging progress live — you know at a glance when a battery is done. Reliable for 24×7 commercial use since 2000.
Home Inverter & UPS Users
Your Exide, Luminous or Amaron tubular battery is taking too long to charge, or it is not holding backup as long as it used to. Boost mode pushes full 10A current to recover the battery fast. Then flip to Float mode — the charger trickle-maintains at exactly the right voltage forever, without overcharging or overheating the battery. Works with 100Ah to 220Ah tubular and sealed SMF batteries from every major Indian brand. Extends battery life significantly.
Factory, Hospital & Plant Managers
Your DG set or genset is the last line of defence — but a dead starter battery means the generator does not start when mains power fails. Float mode keeps the 12V or 24V starter battery at 100% charge every minute of every day. When power trips, the generator fires instantly. Zero downtime, zero missed starts. Critical for factories, hospitals, cold storage, data centres and housing societies where any delay has serious consequences.
Fleet & Transport Operators
Your fleet has Tata trucks on 24V, Mahindra pickups on 12V, Bajaj tempos on 12V, and e-rickshaws on 24V — all at the same depot. With auto voltage detection, one charger handles them all without any manual setting changes. Variable current knob lets your mechanic match the charge rate to the battery size. No more dead batteries in the morning, no more drivers waiting. One charger replaces four.
Solar & Off-Grid Users
Your rooftop solar is not generating enough on overcast days or winters. This charger plugs into the grid as a backup, charging your 12V or 24V deep-cycle battery bank safely. As the battery fills, current tapers automatically — no risk of overcharging even if you leave it overnight. The 2–3A low setting is specifically right for GEL and AGM batteries used in off-grid solar setups across India's villages and rural areas.
Farmers & Rural Users
Your village grid drops to 160V at peak hours and spikes to 280V at night — most city chargers burn out within months. This SMPS charger is built for exactly India's rural grid with a wide 160–280V input that handles every fluctuation. One charger for the tractor (12V), the irrigation pump DG set (12V/24V) and the e-rickshaw (24V). Delivered to your doorstep anywhere in India in 2–7 days.
Battery Dealers & Auto Parts Shops
You sell and service batteries. You need a charger that charges any battery your customer brings in — 12V car, 24V truck, 100Ah inverter, 35Ah bike — without switching equipment. The variable knob and auto voltage detection make that possible. Bulk dealer pricing available. Most battery dealers across India order 5–10 units at a time. WhatsApp or call for wholesale rates.
CCTV & Security System Installers
You install CCTV, fire alarm, access control and intrusion detection systems. Every system has a 12V SMF or VRLA backup battery that must stay at 100% permanently. Float mode with the 2A low-current setting keeps these small sensitive batteries healthy for years without overcharging or drying out. One charger per installation site, or one for the workshop to refresh returned batteries.
Hotels, Hospitals & Housing Societies
Every guest room, ICU and lift-lobby depends on your backup power running without fail. Float mode keeps the DG set starter battery, the UPS battery bank and the fire panel battery at 100% charge around the clock. When power trips — and it will — everything starts instantly. Society facilities managers, hospital biomedical engineers and hotel maintenance heads across India order this charger for exactly this reason.

Frequently Asked Questions
What is the difference between Boost mode and Float mode?
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 to maintain the battery at 100% indefinitely without overcharging — ideal for DG sets, inverters, gensets and vehicles kept on standby. Toggle between the two using the front-panel switch any time.
Does the charger switch to maintainer mode automatically when the battery is full?
Yes. As the battery charges, the current reading on the digital ammeter drops steadily. When the battery is fully charged, the current falls to near 0A — the charger automatically enters maintainer mode and keeps the battery topped up without risk of overcharging. You can leave it connected safely for weeks or months.
Does it auto-detect 12V and 24V — do I need to set it manually?
No manual setting needed. The charger automatically detects whether the connected battery is 12V or 24V. This prevents wrong connections and protects both the charger and the battery — especially useful in mixed workshops with both 12V and 24V batteries.
What battery types and sizes is it compatible with?
Works with all 12V and 24V lead-acid batteries — tubular, flat-plate, SMF, VRLA, sealed and GEL — from 30Ah to 200Ah+. Compatible with major Indian brands including Exide, Luminous, Amaron and Su-Kam. The variable knob lets you set the correct current for the battery size.
Can I use it as a DG set battery charger or genset battery charger?
Yes — this is one of the most common uses. In Float mode, the charger keeps the DG set's 12V or 24V starter battery at 100% charge at all times. When mains power fails, the generator starts instantly without delay. Critical for factories, hospitals, housing societies and any establishment where generator start time matters.
Can I use it as an inverter battery charger for my home?
Yes. Boost mode charges a discharged tubular or SMF inverter battery (Exide, Luminous, Amaron) back to full. Float mode then maintains it at 100% during long power cuts without overcharging — no gassing, no water loss, longer battery life. Works with 100Ah to 220Ah tubular and sealed batteries.
What does the 6-step knob do?
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 faster charging of large 150–200Ah tubular or truck batteries. The digital ammeter shows live current so you always know exactly what is happening.
Does it work on Indian rural grid with voltage fluctuations?
Yes. The wide 160–280V AC input is specifically designed for India's grid — rural areas where voltage can drop to 160V during peak hours or spike above 250V at night. The SMPS technology handles these fluctuations without damage to the charger or the battery.

Kya yeh charger Exide, Luminous ya Amaron inverter battery ke liye kaam karta hai?
Haan — yeh charger Exide InvaMaster, Luminous Red Charge, Amaron Inverter, Su-Kam Shakti aur India ki har tubular, SMF aur VRLA battery ke liye kaam karta hai. 100Ah ho ya 220Ah, 12V ho ya 24V — variable knob se sahi current set karo aur charger baaki sab khud sambhal leta hai. Boost mode se jaldi charge karo, Float mode se hamesha full rakho.
Inverter battery backup kaise badhaye — battery jaldi kyon discharge hoti 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 full charge karta hai aur Float mode usse permanently 100% par maintain karta hai — bina overcharge ke. SMPS technology current automatically taper karti hai jab battery full ho jaati hai, isliye battery ki life bhi badhti hai.
Is SMPS charger better than transformer charger for inverter battery?
Yes — significantly. A transformer charger pushes fixed current even after the battery is full, causing overcharging, acid gassing, water loss and plate damage. This kills most Indian inverter batteries within 2–3 years. An SMPS charger automatically tapers current to near-zero when the battery is full — no overcharging is possible. It also has Float mode for permanent maintenance, variable current for any battery size, auto 12V/24V detection and a digital ammeter so you can see exactly what is happening. The cost of one replacement Exide or Luminous tubular battery (₹8,000–₹15,000) far exceeds the cost of this charger.
How long does it take to charge a 150Ah inverter battery at 10 Amps?
A fully discharged 150Ah tubular inverter battery takes approximately 17–18 hours to charge 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 on the charger shows current dropping in real time — when it reaches near 0A, the battery is full. Note: these are times from fully discharged. A partially discharged battery will take less time.
What is the difference between a battery charger and a battery maintainer?
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) keeps an already-full battery at 100% charge indefinitely by supplying only the small current needed to offset the battery's natural self-discharge. This charger does both: use Boost mode to charge a depleted battery, then switch to Float mode to maintain it permanently. This is why it is called a Float Cum Boost Charger (FCBC) — it is a charger and a maintainer in one unit.
