CanBus Charging
I was looking for a charger that would work with my CanBus system and after looking into BMW chargers that were over the top on price I found this little gem that works out perfectly.

Nice Electronic Features, Easy to Use
I purchased the OptiMate 4 since it was one of the brands recommended in my Ninja 300 owner's manual and highly recommended by other reviewers. I used it for the first time today, since my bike had not been run for about 8 days due to a vacation trip.

My first experience was very positive. It fired right up and the Optimate:
- Confirmed the program was set properly for my bike
- Checked my battery was in a rechargable condition
- Automatically started with a "surge" program shifting between 0.2 and 0.8 amps to give it quick boost
- Automatically shifted to 0.2 amp pulse (trickle) charge
- Automatically ran a 30 min diagnostic to confirm the battery would hold charge

Now I can hop on and know that the battery is fully charged and in good condition. It was all super easy!

Great product, read the instructions and warnings
So I wasn't exactly sure what kind of charger I would need for the motorcycle that I purchased . I watched a lot of reviews on YouTube but I also knew a lot about battery chargers to begin with as I work on cars for a living . Most battery chargers maintain your battery at or close to 100% . If you're looking just to charge your battery up these types of Chargers will do well . I wasn't looking just to charge my battery I wanted to cycle my battery as if to say, the bike was running, I was using it on a regular basis, and that's the way the battery would live it's life . I chose this battery cycler, or as I call it because that's what it does it cycles the battery as if you were using it on a regular basis and not just charging it up to, or close to 100% . I've used this charger on two different bikes now and it's done great. I always find my battery charged and ready to go but not smoking or hot . I took the advice for purchasing this battery cycler off of a Moto Vlogger by the name of Shaun Smoke. He has a channel on YouTube you should check him out.

Easy to use
I thought the unit would require much input from the user as it has a lot of features. Once the unit is connected to the battery, it is just plug and play. It does all the work and decides how best to charge your battery. I've had it plugged in continuously to my bike, and the unit does not over heat.

Good choice for slow charge
I first used this on a nearly 100% dead sealed battery. I plugged it into a power lead that I already had installed on my bike and it worked well. This is a low amperage charger so it took nearly 2 days to charge to full.
I would have given it 5 stars, but the indicator lights are a bit confusing, so for the first several hours I wasn't sure if it was charging or not. They could have designed this better, but would probably mean adding a few more lights and increasing the cost.

Does everything Automatically
I did tons of research to find a charger that suited my bike. Triumph has their own version but as it turns out theirs is wrong due to SAE/BMW connections. The Optimate 4 does everything that the Triumph 3 version does except it is rated for cold weather, costs less at Revzilla, and has the proper SAE connectors.

This tender does everything on its own although the directions are complicated. Just plug it in and leave it there as long as you want. I have been using it for quite some time.

No brain charger
Before I knew what I was doing, I let my battery die.
Bought this, plugged it in and was back in business.
Ran a lead from the battery to the back seat compartment and keep the Ninja charged when not riding.

Sad now, it's in the garage for the winter. Maintain light is on so I know it'll start in the spring.

Great battery charger/maintainer!
I like this charger a lot! It's simple, plug it in and there ya go. I was looking for a charger to maintain my battery threw winter months with a quick connect cord for ease of maintenance from here on. After reviewing all chargers out there I kept coming back to this one. Most major Moto manufacturers recommend this charger (Yamaha, which I ride) and a couple even have there names on this charger, that tells me something! It really is easy to understand - It test, red bad, yellow not so bad, green good, it charges as needed then test again. Simple! After initial test and charge, it test every hr and keeps a full charge on battery without a constant trickle charge, I like that to. Installation is easy of quick connect cord (a must) and everything is great quality. So far it has worked perfect for me and now with the quick connect cord hooked up I don't have to raise the tank on my FZ6 to get to my battery for testing and charging. I like it! Thanks Revzilla!

Can I use this on a HD iron 883?
RAFAEL C on Sep 7, 2016
BEST ANSWER: Printed on your battery will be the battery type. Per the manual. the Techmate Optimate charger is designed to be used with 12 volt lead acid batteries (standard, AGM-MF, or GEL type). It is not to be used with NiCd, Li-ion, or non-rechargeable batteries. It works well but I don't know your battery type.
does this product have a din I can connect directly to din accessory connector on r1200 rs?
A C on Feb 1, 2017
BEST ANSWER: No the only connection to the charger is via SAE connectors. you would have to mechanically splice to get a different connection.
I have a 2016 BMW S1000R do i need this one or the CANbus version?
