How long does it take full charge?** A: As a base line it is pure math. If you have a 200 AH battery that is half charged it will take 100 AH worth of charging to bring it up to full. This charger has a max 20A rating so 100 AH divided by 20 A = 5 hours. Since nothing works at 100% efficiency and since the charge rate is variable you should add 10% - 20% in charge time, or up to 1 additional hour. Call it 5 to 6 hours to charge your 50% depleted battery. That is not only true for this charger but virtually ALL chargers / charge rates. Do the math for a 5 Amp charger or for a 40 Amp charger. The formula is the same. **Q: You mentioned that after a lifepo4 charge, there will be a power failure!’… Can you please explain what is the “failure”?** A: Hello, friend. For example, the P20 Smart Battery Charger normally charges the 12V Lifepo4 Battery to 14.6V and automatically stops working, because the measured Battery characteristics may be about 14.3V, which is considered normal if it is lower. **Q: Can this item be used to recharge the gel batteries for my electric scooter?** A: Hello! Yes, smart chargers. Lithium, Lifepo4, Lead acid (AGM/Gel/SLA..) Battery charger, trickle charger. Adjustable current, optional battery type. **Q: I have been leaving a 12v 100ah deep cycle battery agm fir 3 days straight on pulse/repair mode. how long should the charger take?** A: no longer than 12 hours i would try another charger. if it works then your 1st charger is bad ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product. *by P***R on 20 July 2025* Great product Light weight, Easy to use.
