Plug in — the charger automatically detects whether your battery is 12V or 24V. No manual switch or selector needed.
Turn the 6-step knob to set 0–25A. Match the current to your battery capacity — lower for small batteries, higher for large.
As the battery charges up, current drops on its own. Watch it live on the digital ammeter display in real time.
When the battery is full, the charger automatically switches to float/maintainer mode — no overcharging, no damage, ever.
Sold from Delhi. Ships to all cities, towns and villages in India in approx. 2–7 business days.
E-rickshaws run on 4×12V or 2×24V lead-acid batteries (100–200Ah). The 0–25A variable knob lets fleet operators, battery dealers, and repair workshops across UP, Bihar, Delhi, West Bengal, and Maharashtra set the exact current for any battery bank size.
Industrial forklifts and electric stackers run on 24V lead-acid traction batteries (200–500Ah). The high 25A output with variable current control allows efficient charging for multi-shift warehouse operations — factories, cold storages, FMCG warehouses, and distribution centres pan India.
Charges 12V or 24V tubular, flat-plate, and SMF inverter batteries (100–220Ah) from brands like Exide, Luminous, and Amaron. The 25A output significantly cuts charging time for large tubular batteries. Maintainer mode prevents overcharging during long power cuts.
Heavy commercial vehicles — trucks, buses, tippers, and trailers — run on 24V battery systems (2×12V in series). Used by fleet operators and commercial garages to charge and recondition 24V truck batteries. Auto voltage detection prevents wrong-voltage connections.
Generator starter batteries (12V or 24V, 40–120Ah) must stay at full charge for instant start readiness. Maintainer mode keeps DG set batteries at 100% — critical for hospitals, factories, housing societies, and data centres that depend on reliable generator start-up.
Auto Mains Failure (AMF) panels use a 12V VRLA backup battery to sense grid failure and auto-start the generator. Maintainer mode keeps the AMF panel battery at 100% charge — ensuring the auto-start never fails when the grid goes down.
Used as a mains-backup charger for 12V or 24V solar battery banks. When solar generation is insufficient on rainy or cloudy days, this variable SMPS charger tops up deep-cycle lead-acid batteries — ensuring uninterrupted backup power for homes, shops, and farms.
Telecom BTS sites use banks of 12V VRLA batteries (100–200Ah) for backup power. Used by tower maintenance contractors and infra companies to charge individual 12V cells during servicing and battery replacement cycles at tower sites pan India.
Industrial floor scrubbers and sweepers in malls, airports, hospitals, and warehouses run on 24V deep-cycle batteries (100–200Ah). The 0–25A adjustable output and maintainer mode make it ideal for overnight charging between cleaning shifts without overcharge damage.
Battery-powered scissor lifts and aerial work platforms at construction sites and warehouses operate on 24V lead-acid systems. The 25A output charges large traction batteries quickly between shifts, keeping equipment operational.
Car, SUV, and commercial vehicle workshops use this daily for customer batteries (35–100Ah, 12V). The 25A output charges a flat car battery in under 2 hours. The variable knob ensures safe charging for both small 35Ah car batteries and large 100Ah SUV batteries.
Farm tractors and agricultural machinery use 12V lead-acid starter batteries (80–180Ah). Widely used by tractor dealers, kisan service centres, and workshops across Punjab, Haryana, MP, and Maharashtra to charge and recondition flat tractor batteries.

It is a 0–25A variable current charger. The 6-step knob lets you increase the charging current in steps up to 25 amps. Set a lower current for small batteries (e.g., 5A for a 50Ah car battery) and a higher current for large batteries (e.g., 20–25A for a 200Ah inverter or e-rickshaw battery).
Yes. As the battery voltage rises during charging, the current drawn drops automatically — watch it live on the digital ammeter display. When the battery is full, current drops to near zero and the charger auto-switches to maintainer (float) mode.
When the battery is fully charged, the charger auto-switches to float/maintainer mode — supplying just enough current to keep the battery at 100% without overcharging. This is essential for DG set batteries, AMF panel batteries, inverter batteries, and e-rickshaw batteries that stay connected for extended periods.
Yes. The charger automatically detects whether the connected battery is 12V or 24V — no manual selector switch needed. It then charges at the correct voltage profile for that battery system.
All 12V and 24V lead-acid battery types: tubular (inverter), flat-plate, SMF, VRLA, GEL, and flooded wet-cell batteries. Compatible with battery capacities from 40Ah to 250Ah+. Suitable for inverter, e-rickshaw, forklift, truck, tractor, DG set, solar, AMF panel, and telecom applications.
