Good motorbike battery charger
It works just at it says in the instructions and easy to use.

Biker must have!
Every biker should own one of these!!This keeps your battery in perfect condition so it will start every time. Mine has also brought an old battery back to life and now is my spare (though with this bit of kit it will never get used)
User
A reliable and good value product
Used for last 2mths and working fine. Previous model used for 7yrs, and though it was working fine thought it time to buy the latest model. Used with my motorbike when it's garaged for trickle charging.

Excellent
Excellent way to keep your battery topped up

Keeps my battery charged
I like that this item works and comes with a plug attached and bizarre as it may seem. I use this battery charger to charge my battery. Who'd have thought. ;-)

Great value
Fantastic! You know exactly what you’re getting. It may not have the features of a more expensive version, but what do you actually need? You plug it in and it maintains your battery. I’m going to buy more for my other bikes now.

Will save much hassle if there is ever a flat battery issue.
My Rebel 1100 came with the adapter already installed. The bike was left standing for several months and as expected failed to start. After some research, I managed to find this kit, plugged the charger in, a 20 minute charge and the bike started up perfectly. This has become a vital piece of kit for this bike as the battery is not easily accessible, so if you are in the same boat.... Or indeed have a similar awkward to access battery, this will save much hassle if there is ever a flat battery issue. Although I didn’t have to install the cable from the battery, it does look like a simple, one off job.
