Customer Reviews for Oxford Solariser Optimiser

August 14, 2022 - by Lee M


I can only give an average rating because I don't know how well it actually works on the charging. I bought it on a offer and I was going on a camping trip. As I have a alarm on the bike thought this could be ideal as a precaution on leaving the bike standing for a long period in a middle of a field. The length of the lead were long enough to place anywhere on the bike. Comes with crocodile type clips and and lead to hard wire to bike. The only annoying thing would be the connection type not being an SAE type or the option to do so, as I already have an SAE hidden in the fairing on both of my bikes. Just means another addition to the battery. Not sure if can get an extra battery connector or I'll have to take it off every time I want to use a different bike.

Not impressed.

I've had this for over a month and even with clear strong sunlight the battery only seems to maintain charge rather than increasing. On darker days it merely slows the drain. All I have connected live is a Biketrac Tracker. I would return if I could as I'll have to buy a more powerful trickle charger from another brand.

Does what it says on the tin

I brought this product as I had fitted a mains optimiser which I plugged in when I knew I wasn't using my bike for a day or two, however have looked at hot to reduce energy and so far this product is working really well I have wired up the connector and fitted the solar panel outside running into my garage the cable is just long enough (could do with being a little longer) now I plug this in once I get home from work so that it keeps the battery healthy all year round. Very happy thus far just hope during the winter months it works just as well

Still road testing it

Worked pretty well whilst the battery was off the bike and inside over the winter. Now it's installed i've not started it for a few weeks since so it will be a good test when i go out to it this week to start it. Will put an update when i do. On the plus side it indicates it's charging even at night under the fluorescent tubes in the car park where i keep it.

Simple to use

Great for when you have no nearby power supply where your bike stored. Not waterproof so I put mine in a heat shrink bag, only been in use for a short time, a winter on the roof of my garage will be the real test

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 -  http://www.oxfordproducts.com/motorcycle/brands/oxford/battery_care_and_power_accessories/3mtr_extension_lead_sae_to_sae_connector/?PHPSESSID=d6n54jssgdhtc3t25jplsq2cj2

    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.
