Short Answer: 4 hours maximum for a full recharge.
Detail: Keep in mind that if the electric scooter battery is at 50% discharge, it will only take 2 hours to recharge. After you have recharged your eco friendly electric scooter battery it should be pulled off the charger. We do not want to leave the charger connected to it for an extended period of time (or overnight due to unexpected power surges, outages etc.) At full recharge, the Triad 3 wheel scooter smart charger will stop taking power from the wall socket. Its designed to stay on to alert you with a green light indicator when the battery is charged. When the battery is charged, the battery becomes the power source and the charger will pull a small amount of energy from the battery to keep the green LED charge indicator lit indicating a full charge. If you are consistently driving your Triad at 15 mph, 18 mph or maximum speed, a higher weight capacity and operations in the max speed setting for high resistance areas like grass or gravel will require more frequent charging practices to maintain battery life.
Red Light and charger fan is ON means: I’m still charging. Green Light with fan is OFF means: I’m Charged! Unplug me please!
Overcharge protection within the charger will shut off the power coming in from the wall socket to the charger once the battery sends a full charge signal to the charger indicating that the battery is full. Once the battery is fully charged, its good practice to remove the charger from the battery (or electric scooter charging input).
How do I store my battery when its not being used?
You can remove the battery and store your folding electric scooter until you are ready to use it again. If the battery is being stored, then we should watch the BMS app on your phone to charge the battery up to a maximum of 80%. If you have a Non BMS battery, disconnect it before there’s a full charge cycle complete. A good dormant charge is about an hour of charging time which reads in the yellow indicator on the throttle. The green light on the throttle battery charge indicator will not be lit in the 70-80% range. Storing fully charged batteries will accelerate the discharge percentage in dormancy when battery is not being used. Think of steam from boiling water compared to room temp water. It takes a lot longer for water at room temp to evaporate. Battery is the same in this sense. Fully charged batteries hold more of an intense charge waiting to be used.
Even when being stored a full battery says, “I’M READY I’M READY C'MON LETS GO! NOW, NOW, NOW, LETS GO! LETS GO! CMON LETS GO! WHAT ARE YOU WAITING FOR?”, and the battery’s cells want to perform for use at a moment’s notice.
Therefore, if the battery is stored at 70-80% state of charge (85% max). It will store longer and in better condition than a battery that is stored at 100% full charge.
The 80% charged dormant battery says, “Hey, I’m here when you need me. We can go whenever you’re ready. I’m relaxing right now. Just do me a favor, and plan ahead a couple hours to charge me up fully when you're ready to go the distance.”
Over a period of 60 days a battery that was stored at 80% will lose energy with less force when not being used than a fully charged battery being stored over the same time frame.
What happens if I don’t charge my battery for a long time?
At 10 weeks without charging it is critical to get a charge. We like to have at least 1 hour of charge every 30 days but if that is not possible, 1.5 hours charge after 6-8 weeks is the limitation without pushing it too much. Once it reaches below 48V operating voltage [46v/44v for example], there’s a voltage limiter chip inside the battery that is basically hardware lockout that activates to prevent charging for safety purposes. When a battery falls below operating voltage the battery may not be able to be recovered with normal charging in order to prevent electrical malfunction.
If it does recharge when the battery is below operating voltage, [at times it can, 47V / 47.6V for example] we could possibly experience what we call cell stunting where some of the cells in the series may not fully recharge. This can limit the distance on the battery forever, and you might experience an sudden power failure even though the battery says its fully charged on the throttle LED reading. For example 30% of the battery may not even charge due to cell stunting and power isolation quarantine of part of the battery’s cells, where those parts of the series of cells are being prevented charging completely.
