Why This 6A SMPS Charger Outperforms Ordinary Transformer Chargers
SMPS delivers precise voltage and current. Old transformer chargers overheat and shorten battery life. This charger is built for 220V Indian mains, 45°C summers, and 24×7 commercial use.
- 🔄Auto Voltage Detection
Detects 12V or 24V instantly. No manual switch. No wrong-voltage damage.
- 🎛️5-Step Rotary Current Knob
1.2A → 2.4A → 3.6A → 4.8A → 6A. Exact current for every battery from 4Ah to 100Ah.
- 📟Live Digital Ammeter
Real-time display. Drops to zero when fully charged — zero overcharging risk.
- 🛠️FCBC Battery Repair (Desulphation)
Breaks lead sulphate crystals off plates — the #1 cause of premature battery failure in India.
- 🔋Dead Battery Pickup
Revives batteries below 8V where most chargers refuse to start.
- 🛡️Triple Safety Protection
Reverse polarity + overload + short circuit. Safe for homes and workshops.
- 🌡️45°C+ Rated — Made for Indian Summers
Heavy-duty winding and high-speed fan for non-AC garages all year.
- 🔁24×7 Continuous Duty
Runs round the clock. Transformer chargers cannot match this.
Boost Mode vs Float Mode — When to Use Which
FCBC (Float Cum Boost Charging) means one charger handles both active charging and long-term maintenance.
⚡ Boost Mode — Charge & Repair
For flat, dead or discharged batteries. Runs desulphation to break sulphate crystals and restore capacity. Use for any battery needing active charging.
🌿 Float Mode — Maintain & Store
Holds battery at ~13.6V (12V) or ~27.2V (24V) without overcharging or boiling electrolyte. Ideal for showrooms, workshops, and long-term storage.
How to Charge a Battery with the 12V 24V 6A SMPS Charger
- Connect clamps to battery
Red → positive (+) · Black → negative (−). Clean corroded terminals before connecting.
- Plug into 220V socket
Charger auto-detects 12V or 24V in seconds. Digital ammeter lights up.
- Select Boost or Float mode
Boost for flat or dead battery. Float to maintain a fully charged battery.
- Set the current knob
~10% of battery Ah — 60Ah car = 6A · 12Ah bike = 1.2A · 100Ah inverter = 6A.
- Disconnect when done
Ammeter near zero = fully charged. Unplug socket, then black clamp, then red.
