Tecmate Optimate 2 Duo, TM-551, Bronze Series: 5-Step 12V / 12.8V 2A Sealed Battery Charger & maintainer, Blue

I purchased this several months ago and it has worked well to charge my Ducati motorcycle. Absolutely no issues and the reason I bought it is that this company actually developed the Ducati branded chargers, which are sold for a lot more. Overall, a really solid charger and I would recommend.

I use this alot and I like it

I bought this Optimate Duo to keep the Shorai LiFe battery in my KTM 690 Duke in top shape. Very affordable and works great with the latest lithium iron motorcycle batteries. Highly recommended.

Bought one for my Goldwing so it's ready to go at a moments notice. Liked it so well I bought a second for my lawnmower.

I've boughten a few of these chargers and they are amazing. Set it and forget it. Your batteries will last longer and in the long run this charger will save you money. A new battery is more than this charger alone. Maintenance is everything. Take care of your belongings people.

This is my second one that I’ve bought and they both work perfectly. Batteries last longer than using a trickle charger

Bought this to keep my Shorai lithium battery maintained. But it also works great for my Porsche’s regular battery too.

Batteries are too expensive to replace. I have 5 Tecmate Optimates. Our climate is very cold for 5-6 months a year. These units maintain my welder, 0-Turn mower, tractor, tiller and generators without a single gliche. Great product.
