OptiMate3 0.8A, Smart Battery Saving Charger for 12V Lead-acid Motorcycle and Powersport Batteries

Easy to use and works great. Highly recommend.

Excellent Quality Battery Charger and Maintainer. This OptiMATE 3 x2 (Dual) is compact in size (7" x 5" x 2") with nail/screw slots x2 on top and mainly for use on motorcycle batteries(9.1Ah & 6.3Ah). I am using OptiMATE since 6 years (OptiMATE 5 Start/Stop for Mercedes/BMW) and OptiMATE 4 for motorcycles in garage and they work flawless to charge and maintain batteries. Highly recommended. Better quality and performance than Chinese counterparts...

WISH I KNOW ABOUT THIS SOONER. THIS CHARGER HAS MADE A HUGE DIFF IN GETTING MY BIKE CHARGED. BEFORE I HAD A CHEAP CHARGER AROUND 30.00 AND WAS WONDERING WHY I COULDNT KEEP A CHARGE. AFTER CHANGING OUT- MAN!! I DO RECOMMEND. ITS WORTH THE MONEY.

Love these chargers

Works great on my Honda CRF100F.

I've been using battery tender brand chargers, but needed something that would take better care of cranky batteries. This charger has "No risk of overcharging. Totally safe for vehicle electronics. Sparks suppressed. Safe for long-term battery maintenance. Automatic shut-down if short-circuited or battery disconnected." "Safe for electronics" is important when using CanBus systems. However, It's not a very user friendly. The user interface consists of lights that indicate the "charging" state. The included instructions aren't clear of all the states and the meaning of all the light colors/blinking. A portion of the process is a 12hour charge test cycle, so for effective use you have to leave the Optimate connected for a long time. As long as you're not in a rush this is a good charger. You just need to let it do its thing.

I purchased this in 2017 and have kept it on my tractor when the tractor was parked 24/7. My battery is still in top condition with plenty of cold-cranking amps. I do not use my tractor a lot. It sits in the shed more than it is used. Sometimes for up to three months at a time in the deep freezing weather. I can't say enough for this device except that you need one if you want to keep a battery always ready at a moment's notice. I plan to buy a second one to connect to a spare battery I keep for backup. On a farm and several trucks, jeep, tractors, etc, there are plenty of batteries.

Great fit and finish. Technologically capable to handle new bikes and vintage regardless of battery technology. Bright LEDs are easy to read and understand. If you have more than two bikes or vehicles that are stored for long periods, it’s a no brainer.
