🔌 TecMate TM-341DUAL OptiMate 4DUAL 1 Amp Weatherproof Desulfator Charger/Maintainer Review

The Optimate is one of the best chargers on the market, period! They are recommended by BMW motorcycle dealers. He revived several batteries for me!

It's a bit hard to figure out what he's doing when he's doing it, so I watch some YouTube videos. It seems to go well with my two Yamaha snowmobiles.

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

I just took the unit out of the box after sitting on a shelf for 3 years and when I turned it on the lights flashed and then wouldn't come on again. I try a different outlet, but there is no light. This is one of the two units I bought, the second seems fine. I will look for a way to return it.

I was a little confused by the instructions. What am I doing? In the end, all you have to do is plug it in, plug in the battery and wait for the light to turn green. I was confused because I thought I had to do something to turn it on, change modes or something, but everything is completely automatic. It charged my Yuasa YTX9-BS motorcycle battery from zero to full overnight. No complaints (except for the operating instructions)

I currently have 3 of these chargers. I use one at home, one in the country and one I keep in my truck. I have a fast connection to quads, lawn mowers and vehicles. I connect this to batteries in the winter to conserve battery power. I have had no issues with the batteries overcharging or losing effectiveness when using this charger. I don't have any empirical data, but my batteries have performed better over the past two years (in cold winters) after using these chargers.

Excellent unit. Now I have three, one of which is about ten years old and it still works great. They are an excellent product to keep motorcycle batteries alive for many years. One of the batteries serviced by these departments is a battery I bought for one of my bikes in 2009. I thought I would replace that battery this year, but it's clearly not necessary. The battery is like new and holds a full charge. Part of the secret is that you connect the device every time you park your bike.

This is an amazing product. I connected the included adapter to my Ducati Monster S4R and can just plug in this charger when I need to keep the battery fresh (or just leave it on if you prefer). I also use the included clamp set to hold the battery pack. My Husqvarna lawnmower battery is good (Husqvarna YTH23V48-CA 48" 724cc 23hp Briggs & Stratton Intek V-Twin Pedal Activated Hydrostatic Transmission Garden Tractor (CARB Compliant) - great mower, also bought from Revain) . It is better than…

I bought this to rejuvenate and maintain the extra battery by bypassing the built in charger which is not that difficult. The backpack charger damages batteries. This thing saves her! It runs diagnostics, follows the appropriate flowchart, performs various complex charging protocols and then enters a very complex service mode, everything is fully automatic, keeping you informed at every step. And importantly, the end result is a better charge and a restored battery. Just to see what it can do I
