I needed a charger that would work with the new gel type battery in my motorcycle. This is simple to use, tells you what it's doing, has mutiple intelligent functions, and works great.

So far, it works great. It seems to be well constructed and charges my batteries as described, however, it might be a little over sensitive with the battery testing cycle. It did correctly diagnose a bad battery but it also diagnosed another working battery as needing replaced. Maybe the battery will eventually need replaced but so far it keeps working without my intervention.

I highly recommend this battery reconditioner/charger! Out of 4 dead motorcycle batteries that wouldn't charge normally, I was able to save 3. The 4th had an internal short and couldn't be repaired. With the cost of motorcycle batteries, this device has paid for itself a few times over already! This was a very good investment.

Have tried this on many different batteries from small motorcycle batteries through large diesel equipment batteries. Results are mixed. I had several medium sized batteries on ATV's that I was having problems with. The charger went through all its tests and said those batteries were good but they were not and had to be replaced. It does make a good small charger that can be left connected in the off season to maintain a battery but its diagnostic functions aren't trustworthy. Also, you will definitely need the manual to figure out what all the flashing lights mean. Keep in mind this unit outputs less than one amp so if you have a large heavily discharged battery it will take a very long time to charge.

I have owned the product for five years while living in germany.

Simpley Awesome.

I operate the system on my Honda NC35 and Harley Davidson V-rod. V-rod security systems will eat a battery faster than you expect.

Plug in and let it go. Especially during times of possible freezing conditions. My garage was in a the hill side and more than 100 years old so cold was the big battery killer here.

Buy the permanet hard wire kit and hide it all nice and tidy. People will never even see it.
