I’ve been using it every day on my battery bank and to condition my car batteries for over 6 years and I trust it 100%. If you’re just wondering what’s the best charger for the money in the “float/trickle” category, I always turn to this charger and float maintainer seen on Amazon. While both can effectively charge and top off your battery if used correctly, there are a few precautions you’ll want to take before hooking these up to your car or other battery and simply setting it and forgetting it. Don’t be fooled, however, as these chargers are not created equal and one can really damage your batteries if used improperly! That is the quick and easy answer, and it may seem like it doesn’t matter which one you choose. Float Charger (Maintainer) Trickle Charger Float Charger (Maintainer) Will charge a battery to 100% Will charge a battery to 100% Will overcharge a battery after it reaches 100% Only outputs current as the battery naturally self-discharges and can accept a current Will kill a battery if left connected to a battery long-term Safe to hook up and use indefinitely
