I have tried numerous battery tenders and most have not lived up to the hype, that being said this is hands down the best one I have owned. I use it primarily on a spyder can am and it has done what the others can’t……. It’s job

This is a replacement to the original one I had purchase 20 years ago. I felt that it was such an awesome charger, that when it stop working, I wanted to replace it. The new one has some operation options which I find a little awkward to use, but in comparison to my old one which was a simple plug in and go, it seems fine.

This is an amazing product. I connected the included adapter to my Ducati Monster S4R and I can just easily connect this charger to it whenever I need to keep the battery fresh (or just leave it on if you want).I also use the included set of clamps to keep the battery healthy on my Husqvarna mower (Husqvarna YTH23V48-CA 48-Inch 724cc 23 HP Briggs & Stratton Intek V-Twin Pedal Activated Hydrostatic Transmission Riding Lawn Tractor (CARB Compliant) - awesome mower also bought on Amazon).It's better than other trickle chargers I've had because it even revives dying batteries and keeps them healthy.If you got this far in the review just click buy. You know you deserve it. :o)

Excellent unit. I now have three, one of them is about ten years old and still working perfectly. They are a superior product for keeping motorcycle batteries alive and working well for years. One of the batteries being serviced by these units is on a battery that was purchased in 2009 for one of my motorcycles. I thought I would replace that battery this year, but there is clearly no need to do so. The battery is like new and holds a full charge. Part of the secret is that you plug the unit in every time you park the bike.

Works grreat!

Optimate is one of the best charger / maintainers on the market, period! BMW motorcycle dealers recommend them. It has resurrected several batteries for me!

Bought 1 and it brought back a battery from the dead, so I bought another one for my other bike. These are the best of the best, worth every penny. Works as it is supposed to. How many times can you actually say that?
