Simple to setup

Great service from SportsBikeShop as usual, replaced a unit delivered with a broken glass. The solariser is simple to set up took 10 minutes to wire on to the bikes battery and ran the wire to the side of the shed, there is a blue light that blinks to indicate its trickle charging.

Good when stopping far from mains power

This is a trickle charger that maintains the battery with daylight/solar energy. It has survived storm Dennis and still functions. I double check that the battery is ok with a mains battery charger every now and again and it seems to be fine. I suspect that if you have an alarm fitted then it would be hard pressed to replace the lost charge from the alarm drain but this is simply sorted by running the bike every few days. It is also easy to carry/strap on your bike when you travel however easily stolen so I have bolted and glue it to my top box.

great product when no electric is possible

This great little solar charger is great when you dont have a socket to plug into for a charger or it's a safe way to keep your bike battery tip top. comes with plenty of leads so every option is available for connection. it costs nothing to run and is a green option for keeping battery maintained.

No more flat battery.

Using the sun to top up the battery via the Oxford Solariser Optimiser fantastic! It works really well this my second Oxford Solariser Optimiser. It is so helpful , with a number of options for connecting it to the battery. It is especially helpful if you don't have a power socket near your bike.

Questions and Answers

Questions and Answers

  • The output of my solar charger is over 20V, can this damage the battery? I only ask as my battery just died and I did have the solar charger plugged in over a long period of time. It may just be a coincidence as the bike is over 10 years old and I does not know how old the battery is. Thanks.

    May 1, 2019

    It is normal for this Solar Optimiser to read over 20V when disconnected from a battery. It has been designed to be used on all 12V batteries for long periods of time and will reduce the power output automatically when connected. Please note however that if the battery drops below a certain voltage (usually 8V), this optimiser may not be able to recover the battery.

  • Will it charge the battery without the ignition switches on via the cigarette lighter socket

    September 24, 2018

    Unfortunately the ignition would need to be left on as the 12v socket is a switched live.

  • Hi Is this solariser ok for keep permanently on my Harley AGM battery?

    August 14, 2018

    The eyelet leads are designed to be left on your motorcycle battery. You can then simply disconnect the solar panel from the eyelet connector when you want to use your motorcycle.

  • Will this SAE adapter enable me to connect this to my exisiting SAE connector on the battery -

    April 23, 2018

    Unfortunately this is not possible, as the Solariser does not use the SAE or TM style connectors, apologies.

  • Does this come with an SAE connector that will fit into the optimate connector already attached to my battery...if not how else do I quickly connect without lifting the seat each time.

    October 27, 2017

    Unfortunately it is not supplied with an SAE connector, but it is supplied with its own connector that can be attached to the battery.

  • Hi is this charger ok for lithium ion battery for my 2007 400cc beta cross bike. Thanks

    September 14, 2017

    We would not recommend the use of this charger on a lithium battery as they require a specific charging program.

  • Will it charge the battery via the 12V outlet on my V-Strom 1000 when ignition is off?

    August 22, 2017

    Unfortunately the ignition would need to be left on as the 12v socket is a switched live.

  • Is the unit waterproof

    August 14, 2017

    The Oxford Solariser is designed to be light weatherproof. It can therefore be used outside but is not waterproof and will not withstand heavy rain or being submerged.

  • How long is the lead ?

    February 24, 2017

    The main power lead is approximately 8 feet in length.
