OHRIJA 12V 5A 24V 2A Intelligent Charging Unit for Motorcycles and Cars | Lead-Acid Battery Restorer | Pulse Restoration with Indicator Light

This charging repair device is specially designed for 12V and 24V lead-acid battery systems and is multi-functional. It uses LED indicator lights to clearly show the charging status, which is simple and intuitive with no complex settings. It is equipped with pulse repair technology, which can effectively reverse battery sulfation and extend the battery life by 2-3 years. It is suitable for motorcycles, cars, trucks, agricultural vehicles, etc.
Main features:
Dual voltage compatibility, automatically detects 12V or 24V
Support 12V and 24V lead-acid battery systems.
12V mode: Outputs 5A current, suitable for motorcycles, ATVs, and small cars.
24V mode: Outputs 2A current, suitable for motorcycles, trucks, vans, large SUVs, and ships.
Pulse Repair Technology
For lead-acid batteries that have suffered sulfation failure, the crystalline form of lead sulfate is decomposed through high-frequency pulse treatment.
Effectively restore battery capacity and save old batteries that have been “left unused for too long and unable to charge”.
Seven-level safety protection
Reverse connection protection: If the positive and negative connections are reversed, the device will not charge and will not be damaged.
Overcharge protection: Once fully charged, it automatically switches to float charging mode.
Short-circuit protection, overcurrent protection, overheating protection, overvoltage protection, anti-reverse current protection.
It is suitable for long-term power connection and can be safely used even during the night or when no one is on duty.

Usage Steps (Simplified):
Connect the charger to the AC power source. The red light turns on.
Connect the red clip to the positive (+) terminal of the battery and the black clip to the negative (-) terminal.
The charging light turns on, indicating the start of charging.
The green light turns on, indicating full charge. At this point, you can disconnect or continue the float charge.
Common Questions:
Q: The LED indicator light keeps flashing red. What should I do?
A: It indicates a fault. Please check if the positive and negative terminals are connected in the wrong way, if the clips are not properly contacting, or if the battery voltage is too low (below 2V).
Question: Can a completely drained battery be repaired?
Answer: If the battery voltage is below 3V, it is recommended to briefly activate it with another charger; this charger will automatically perform a small current activation for batteries with a voltage above 3V.
Q: The indicator light doesn’t light up when charging?
A: Please check if the socket has power or if the power cord is properly plugged in.
