Key Features of the 12V 10 Amp High Frequency Battery Charger India
Digital Ammeter – Live Display
Large digital meter shows live charging current in real time. Watch amps drop as battery fills — you know exactly when charging is complete.
Manual Boost / Float Switch
Flip to BOOST for fast charging of a discharged battery. Flip to FLOAT to safely maintain a full battery without overcharging. You control the mode.
Automatic Battery Maintainer
Current tapers automatically as battery reaches full charge. Charger settles into maintainer mode — safe to leave connected indefinitely.
High Frequency SMPS Technology
High-frequency switching means compact size, less heat, better efficiency and longer charger life versus old transformer-based chargers.
Full Protection Built In
Overload, short circuit and reverse polarity protection. Safe for permanent connection to any 12V lead-acid battery system.
Wide Input: 160–280V AC
Handles Indian grid voltage fluctuations and generator power reliably. No damage from unstable, low or high supply voltage.

How the 12V High Frequency Battery Charger Works
Connect to Battery
Clip red (+) and black (−) leads to terminals. Built-in reverse polarity protection keeps you safe.Set the Current Knob
Turn the 0–10A dial to your target rate. Rule of thumb: 10% of the battery Ah rating.Select Boost or Float
BOOST for charging a flat battery. FLOAT to maintain an already full battery.Watch the Ammeter
Digital display shows live amps. As battery fills, current drops naturally — no guesswork.Maintainer Mode
Amps near-zero means battery is full. Charger auto-maintains safely — leave connected indefinitely.Where the 12V 10 Amp High Frequency Battery Charger Is Used in India

Frequently Asked Questions
What is a 12V 10 Amp High Frequency Battery Charger?
The 12V 10 Amp High Frequency Battery Charger India from Samco Battery uses SMPS technology to charge any 12V lead-acid battery from 7Ah to 220Ah. It runs cooler, is more compact and significantly more efficient than old transformer-based chargers. Available from Delhi and shipped across India.
What does the Boost / Float switch do?
BOOST mode delivers higher voltage for fast active charging — use when the battery is discharged. FLOAT mode reduces voltage to a safe maintenance level, keeping a full battery topped off without overcharging. Toggle manually with the switch on the front panel.
What does "battery maintainer mode" mean?
As the battery approaches full charge, its internal resistance rises and the charging current drops — visible on the digital ammeter. When current reaches near-zero, the charger settles into a low-level maintenance state. It is safe to leave connected indefinitely.
What battery sizes can this charger handle?
Any 12V lead-acid battery from 7Ah (motorbike) to 220Ah (large tubular inverter). Set current to roughly 10% of the battery Ah — e.g. 10A for a 100Ah battery, 5A for a 50Ah battery.
Can it revive a completely dead or flat battery?
Yes. Switch to BOOST mode and set the knob low (1–2A). The charger slowly recovers battery voltage. Once voltage rises, increase current as needed. Works on batteries that fully-automatic chargers reject as "too flat to charge."
What is the price and how do I order?
₹2,951 all taxes included, with free shipping to every city, town and village in India. WhatsApp or call 99539 35912. Dealer and wholesale discounts are available for bulk orders.
