Perfect! Great product, highly recommended! Super easy to use and cheap in power consumption. Wired it directly to the battery with the provided cord. Best bang for the buck! February 17, 2014
Good feedback regarding battery status The indicator lights do a good job in showing the state of your battery but if you don't normally pay attention to these sort of things you're better off with a cheaper product. I bought it mainly because it is advertised for BMW brand bikes February 24, 2014
This product has great features Very easy to use and works as advertised. Plugs right into BMW CANbus with no problems. February 10, 2014
Confusing light show, but great performance. I purchased this charger to maintain the battery on my f800gs over the long winter in Michigan. I had the bike sitting with no charger for a couple months before I purchased this optimate. The battery was sounding weak the one day I was able to ride. Charger plugs right in to the BMW outlet and works seamlessly. The array of LEDs on the charger are a bit confusing, and I had to read the descriptions and watch a couple videos from optimate to decode what the charger was doing. The charger has indicated that it has repaired my battery, and the batter does sound audibly much better. February 10, 2014
Perfect for maintaining battery. This is an excellent product, works flawlessly. I had a problem with a car that doesn't get driven everyday and the battery running down, would still start, but was sure it was hurting the life of the battery.. The Optimate 4 ran through the whole diagnostic and charge procedure like clockwork and now is in maintenance mode. Saves having to buy an expensive replacement battery. I also, have the optimate 1 on my motorcycle, its perfect too. December 23, 2013
Optimate 4 Battery Charger This is fantastic unit, once you know how to use it. The instructions that come with the unit are cryptic at best. Because of this fact, there are many help video's posted online. I Have 1 bike that has CANBUS and 1 that does not. The Optimate handles them both. December 16, 2013
The most portable (lightweight) everything charger! After reading instructions I understood how it worked. My 07 BMW R1200R is now charged up via CAN-BUS. Charge your car, lawn tractor, sailboat trolling motor, etc too! December 22, 2013
Very good charger I needed a charger for the BMW Canbus system. So far it works great! December 16, 2013
