Solid bit of kit - SAE connectors huge improvement

I have had several optimates for my bikes but I was getting fed up with the white plastic connectors breaking, corroding or having wires popping out. this version is just as good as the old V3 optimates but the connector system is a huge improvement. probably cheaper to connect up an SAE for my old one but this one does come CAN bus ready so should be future proof

Well worth the spend!

As always ... excellent pricing and service from SportsBikeShop!! Optimate 4 is a great bit of kit. Have a completely dead battery ... drained by a tracker to within an inch of its life. The battery was in such a state that even the Noco Boost would not start the bike (which is weird - because it is supposed to). Stuck the battery on the Optimate for somewhere between 12 and 24 hours ... and it is back to life as it was. The battery was new a few months before ... and I thought I was going to have to buy another, but my bacon was saved.

Replaces my old 15 year old optimate which still works on my other bike. Does exactly what it says on the box. Keeps the battery fully charged, despite my bike alarm system. Just plug it in and leave it. Totally recommended.

The Choice for me

I have used the 4 since they entered the market and purchased a 2nd for my can bus GSA. Great product.

All good

My previously trusty 23 year old Optimate decided to completely flatten my battery so I have bought this one to take over. So far so good! Great service from Sportsbikeshop.

Top Product

I have purchased several Optimates over the last 20 years, 1 for every one of the 4 bikes in the garage. I have only purchased 2 batteries in the same period so as far as I am concerned the do their job well.

CanBus Charging

Needed the CanBus function of this Charger. Works as it should for my GS and old VFR. Highly recommend Sportsbikeshop as I ordered the wrong leads initially, and they were changed out without any fuss

A simple, effective way to maintain a battery

I bought this after another battery charger let me down and ruined my battery when it went into standby mode after a power cut. My wife's bike came with an Optimate 4 and has done an excellent job of keeping the battery in good condition. Despite being a sophisticated product, it is simply a case of connecting it and letting it do it's work.

Easy to follow instructions, just plug in and let it do it's job. Well made and the lights are self explanatory.

A bit too complex?

Bought this to replace an old optimate I borrowed and needed to return. I hadn't realised the extra stress from not knowing if it was set for CANBUS or not. I think this is more my technophobia than anything fundamentally wrong. Other than that all worked fine.

Improvement on previous model

More sophisticated in its operation but still just has to be connected and it does the rest

New and Better

Bought this to upgrade from my old optimate that I have been using for 18 years and is still going strong on my sons bike. Reason for upgrade due to brand new bike gsxr1000r with canbus system, this unit works on both systems and has already recovered two other standard batteries that have been stood for over 3 years for other vehicles as well as keep my new bike in tip top as the canbus system is very sensitive to slight drops in voltage of the battery with no drain even stood for a couple of weeks. To date as expected from my previous optimate excellent unit plug- go and forget.

Money well spent

Bought the Optimate 4 Battery Optimiser with the intention of plugging it straight into the DIN socket on my motorcycle. Having read all articles about the charger I believed it was the best charger to get as I assumed it had all of the required capabilities and accessories. However when it arrived it had every accessory apart from the required DIN plug. Therefore a further purchase of said plug was required. So slightly more expensive than at first thought. However the Optimate 4 has recovered and recharged my ailing battery, so money well spent in that respect.
