SmartAI™ is featured in the majority of our chargers. It is a comprehensive MICRODIA patented charging technology that safeguards your devices with a multi-protection system.
Essentially, these types of chargers intelligently deliver different current levels throughout different charging stages in order to minimize degradation and prolong battery lifespan up to 30%. It is generally divided into 3 stages. The main characteristic of each stage can be found below:
Stage 1: Bulk Charge
The first stage is called bulk as the key purpose during this stage is to provide a large chunk of current to recharge the battery in a short period of time. It is the most significant stage for batteries that are severely drained. Assuming that the battery first started in a deeply discharged status, the charger would normally give out the highest voltage and amperage that it can produce and that the battery can handle. There is no need to worry about the battery being overheated even if the highest voltage is applied owing to the battery’s natural absorption rate. The risk of overcharging will not occur in this stage as the battery has not even reached its full capacity.
Stage 2: Absorption Charge
The charger can recognize voltage and resistance from the battery ahead of time. After a thorough understanding, the charger will decide the most appropriate stage to charge the battery at. The charger will enter the absorption stage when the battery reaches 80% of its capacity. The voltage emitted from the charger will become more constant and the charge current will decline. The low current emitted throughout this brings up the charge level in a secure way without overheating the battery. However, charging the last 20% of the battery takes significantly longer in this stage than during the bulk stage. The current decline constantly throughout this stage until the battery almost reaches the full capacity
Stage 3: Float Charge
Generally, the charger enters the float stage as early as when the battery capacity reaches 85% with some exceptions of 95%. The voltage will start to taper down while maintaining a constant level. The battery becomes fully charged during this state and maintains a 100% charge indefinitely. The current will slowly decrease until it is considered a trickle in the float stage. It is where the name “trickle charger” is derived from. In short, a low stream of current is going into the battery continuously but only at a safe rate so as to achieve a constant full charge of the battery. It has been certified safe to leave the charger on in the float mode for months on end even though the majority of the battery chargers would be turned off at this point. It is actually a healthy practice for a battery to be at 100% stage of charge.
