12V 20A Inverter Battery Charger (Float Cum Boost SMPS) — Kya Hai, Kiske Liye Hai, Price Kya Hai?
FCBC (Float Cum Boost Charger) ek do-mode SMPS battery charger hai. Boost Mode discharged 12V battery ko full current (0–20A variable) se fast charge karta hai — digital ammeter pe current live track hoti hai aur battery bhar jaane par automatically girne lagti hai. Float Mode fully charged battery ko 13.5–13.8V pe indefinitely maintain karta hai — overcharge impossible, battery permanently connected reh sakti hai.
Kiske liye: Home inverter batteries (Exide, Luminous, Amaron — 100Ah to 220Ah), car batteries (35Ah–100Ah), DG set starter batteries, solar battery banks, telecom tower VRLA, UPS backup. Compatible with all 12V lead-acid chemistries — tubular, flat plate, gel, AGM, SMF/VRLA.
Why FCBC over regular charger: Regular SMPS chargers sirf boost mode dete hain — full charge hone ke baad bhi current dete rehte hain (overcharge risk). FCBC float mode se battery indefinitely connected reh sakti hai. Inverter, DG set, telecom standby batteries ke liye FCBC industry standard hai globally.

Why Trust Samco Battery — Expertise Behind This Charger
Samco Battery, Delhi
Electrochemical Engineering — Yeh Charger Kyun Alag Hai
Samco Battery ke founder Arender Siali ne CECRI (Central Electrochemical Research Institute, Karaikudi) se electrochemistry mein training li hai — CSIR ke under India ka premier battery research institute. Woh SAEST (Society for Advancement of Electrochemical Science & Technology) ke life member hain.
Iska matlab yeh charger ek general electronics manufacturer ne design nahi kiya — ek trained electrochemist ne banaya hai jo battery chemistry deeply samajhta hai: charging voltage thresholds, gassing risk, sulphation recovery, electrolyte behavior, float voltage precision.
Float voltage precision matters: 12V lead-acid battery ki float voltage 13.5–13.8V honi chahiye — 0.2V zyada hua to battery overcharge hoti hai, 0.2V kam hua to self-discharge nahi rukti. Yeh charger is range ko precisely maintain karta hai because the designer understands the electrochemistry, not just the electronics.
Current taper profile: Bulk stage mein full current (0–20A), absorption stage mein taper (battery ke voltage ke hisaab se), float stage mein near-zero — yeh scientifically correct 3-stage profile hai jo battery manufacturer recommendations ke exactly according hai.
2000 se pan India supply — hospitals, factories, telecom companies, housing societies, individual households — sab ke liye reliable charger delivering since 25 years.

Formula: Battery capacity (Ah) ka 10–15% = safe charging current. Example: 150Ah battery → 15–20A dial setting. 40Ah car battery → 4–6A. Digital ammeter pe current track karo — near-zero aye to battery full hai.
3-Stage Charging Science — Exactly Kya Hota Hai Jab Aap Charge Karte Ho
Bulk Charge: 0% → ~80% SOC
Battery bahut discharged hai — charger maximum set current (0–20A dial se set) pe constant current deta hai. Voltage dheere dheere rise karta hai (~11.5V se ~14.4V tak). Digital ammeter pe current approximately stable dikhti hai. Yeh fastest charging stage hai — battery 0 se 80% is stage mein aati hai.
Absorption: ~80% → 100% SOC
Battery voltage 14.2–14.4V ke paas pahunch jaata hai — plates ki charge acceptance capacity kam hone lagti hai. Current automatically taper hoti hai — digital ammeter pe clearly dikhta hai: 20A se 10A, 5A, 2A, 1A. Jab current 1–2A pe stable ho jaye — battery 100% charged hai. Yahi ammeter reading ka sabse important signal hai.
Float Maintenance: Indefinite
FLOAT switch karo — charger voltage 13.5–13.8V pe regulate karta hai. Is voltage pe battery self-discharge compensate hoti hai only (typical 1–5mA). Koi gassing nahi, koi overcharge nahi. Battery months tak connected reh sakti hai — inverter, DG, telecom standby ke liye yahi correct method hai.
Technical Reference — Battery Charging Facts
- Float voltage for 12V lead-acid: 13.5–13.8V (flooded/tubular), 13.6–13.8V (VRLA/SMF/gel) — above 13.8V overcharge risk, below 13.4V battery slowly self-discharges
- Optimal charging current rule: Battery Ah ×10–15% = safe charging current. 150Ah battery → 15–20A maximum. Exceeding this causes excessive gassing, heat, plate damage
- SMPS switching frequency advantage: High-frequency SMPS (20–100 kHz) vs transformer (50 Hz) — 40–45% smaller transformer core, 35–40% lower losses, stable DC output with minimal ripple
- Indian grid compatibility: 160–280V input range — handles low-voltage rural areas (often 160–180V) and high-voltage urban spikes (260–280V) without damage
- Battery life impact: Properly float-charged lead-acid batteries last 30–50% longer than those that are overcharged or left to self-discharge — established electrochemical principle
- Sulphation recovery: Deeply discharged batteries (below 10.5V) develop lead sulphate crystal buildup. Boost mode at low current (2–5A) can recover mildly sulphated batteries by slowly re-dissolving crystals — not always successful but worth attempting before replacement
- Why digital ammeter matters: Unlike voltage meters, ammeter shows actual charge acceptance — near-zero current is the only reliable indicator of full charge regardless of voltage reading variations between battery brands/ages
