I have three of these now, various models to keep all my power sport toys charged and ready to go. I recently bought a classic car that is stored for weeks at a time between driving it and I wanted a charger that was higher capacity than my other ones. If you're just going to use this for a motorcycle, jet ski or similar toy there is no need to by this model. Go with the Optimate 4 as it can also handle CAN BUS systems and costs a little less too. It has plenty of capacity to maintain smaller batteries however if you're going to maintain a car battery I suggest the Optimate 6. My Optimate 3 is now over 10 years old and it has been plugged in most of that time.
