Compact and Efficient Lead Acid Battery Charger 12V 3A
The HOT DD30CRTA controller inside the Lead Acid Battery Charger 12V 3A combines compact design with robust functionality. Users can easily integrate it into automotive, solar, UPS, and industrial applications. The Lead Acid Battery Charger 12V 3A automatically adjusts voltage and current levels to protect batteries from overcharging, deep discharge, and other common battery issues.
Even fully drained batteries are recovered safely with the Lead Acid Battery Charger 12V 3A, starting with a trickle charge to minimize stress on battery plates. This makes the charger ideal for long-term battery maintenance and ensures efficient performance over years of use.
Multi-Stage Charging for Optimal Battery Health
The Lead Acid Battery Charger 12V 3A features four intelligent charging phases to ensure safe and efficient power delivery:
1️⃣ Trickle Charge Mode – Safe Recovery
If a battery is deeply discharged, the Lead Acid Battery Charger 12V 3A initiates trickle charging at approximately 17.5% of the constant current. This careful approach prevents battery plate damage and prepares the battery for full capacity restoration.
2️⃣ Constant Current Mode – Fast and Controlled
Once the battery reaches 75% of its regulation voltage, the Lead Acid Battery Charger 12V 3A delivers a steady 3A current. This phase ensures rapid and controlled charging while avoiding overheating or over-stressing the battery.
3️⃣ Overcharge Mode – Safe Full Capacity
As battery voltage approaches 14.8V, the Lead Acid Battery Charger 12V 3A gradually reduces current to prevent electrolyte loss and swelling. This stage ensures full capacity without compromising battery safety.
4️⃣ Float Charge Mode – Continuous Maintenance
After full charge, the Lead Acid Battery Charger 12V 3A stabilizes voltage at 13.55V. This float charge maintains battery readiness and compensates for self-discharge or external loads without overcharging.
Features That Make the Lead Acid Battery Charger 12V 3A Exceptional
The Lead Acid Battery Charger 12V 3A from NDBC BY LOFTY AGROTECH is not just a simple charger—it is a comprehensive battery management solution that combines precision, safety, and durability. Designed for a wide range of applications, this charger ensures that your 12V lead-acid batteries are maintained efficiently, protected from damage, and always ready for use. Its carefully engineered features provide users with a seamless experience, whether for automotive, industrial, UPS, or solar applications.
PWM Smart Charging Technology
At the heart of this Lead Acid Battery Charger 12V 3A is the Pulse Width Modulation (PWM) smart charging technology. PWM allows the charger to regulate voltage and current with remarkable precision, ensuring that the battery receives the right amount of power at each stage of the charging cycle.
Unlike traditional chargers that deliver a fixed current regardless of battery condition, PWM technology adjusts dynamically, reducing the risk of overheating and improving energy efficiency. This also extends the overall lifespan of the battery by minimizing stress on the internal plates and electrolyte. Users can trust that the Lead Acid Battery Charger 12V 3A will charge their batteries safely, whether they are slightly discharged or fully drained.
Automatic Multi-Stage Protection
One of the standout features of the Lead Acid Battery Charger 12V 3A is its automatic multi-stage protection system. This ensures that the charger intelligently navigates through all the necessary charging phases:
-
Trickle Charge Mode – Safely restores deeply discharged batteries.
-
Constant Current Charge Mode – Provides a steady 3A current for rapid charging.
-
Over-Charge Mode – Reduces current when the battery reaches full capacity to prevent damage.
-
Float Charge Mode – Maintains a steady voltage to keep the battery ready for use without overcharging.
This multi-stage protection system reduces the chances of battery failure, enhances performance, and guarantees a longer lifespan for your 12V lead-acid batteries.
Deep Discharge Recovery
Batteries that are deeply discharged can often be difficult to revive without causing damage. The Lead Acid Battery Charger 12V 3A features a deep discharge recovery function that starts charging slowly and safely, preventing excessive stress on the battery plates.
During this phase, the charger supplies approximately 17.5% of the rated current to gradually bring the voltage up. Once the battery has recovered enough, the charger automatically transitions to the standard charging mode. This feature is especially useful for automotive batteries that may have been left unused for extended periods or solar batteries that experience heavy discharge cycles.
Under-Voltage Lockout
The Lead Acid Battery Charger 12V 3A comes with an under-voltage lockout feature to protect batteries when the input supply is too low. If the supply voltage drops below a safe threshold, the charger automatically suspends operation, preventing reverse current flow and protecting the battery from damage.
This feature is crucial for applications where fluctuating input power can occur, such as solar panels with inconsistent sunlight or portable UPS systems. By ensuring that charging only occurs under safe conditions, this charger safeguards both the battery and the connected devices.
Over-Voltage Protection
Overcharging a battery can lead to electrolyte loss, plate corrosion, and irreversible damage. The Lead Acid Battery Charger 12V 3A includes over-voltage protection that prevents such risks.
When the battery voltage reaches the set threshold—14.8V in overcharge mode—the charger gradually reduces current to avoid stress. Once the battery reaches full charge, it enters float charge mode at 13.55V, maintaining readiness without the risk of overcharging. This ensures optimal battery performance and longevity.
High PWM Switching Frequency
The charger operates at a high PWM switching frequency of 300 kHz, which significantly improves efficiency while minimizing heat generation. This allows the Lead Acid Battery Charger 12V 3A to operate effectively even in high-temperature environments or under continuous charging conditions.
A high switching frequency also contributes to faster response times, better voltage regulation, and improved overall energy efficiency. Users benefit from a charger that is not only safe and reliable but also highly energy-conscious.
Compact and Lightweight Design
The Lead Acid Battery Charger 12V 3A features a compact form factor of 66 × 20 × 12 mm and weighs just 9 grams, making it easy to integrate into tight spaces or portable devices. Despite its small size, the charger delivers the same performance as larger, bulkier units.
This compact and lightweight design is perfect for automotive installations, embedded solar battery systems, UPS units, or any application where space is limited. Users can enjoy easy installation without sacrificing performance or protection.
Wide Battery Compatibility
One of the key advantages of the Lead Acid Battery Charger 12V 3A is its compatibility with a broad range of 12V lead-acid batteries, from small 1Ah units to large 10,000Ah industrial batteries.
