January 3, 2019

Does what it says on the tin.

Everyday Motorbike Battery charger that you can plug in overnight, or simply leave plugged in to keep your battery in top condition through the winter. It comes with a short extension/connection lead which you can attach permanently to the battery, so you don't have to keep taking your saddle off to top up the charge. 2 year Guarantee - For some reason my first one of these died after 1 year, but it was replaced free of charge by SportsBikeShop quickly and without quibble Happy with the charger. Very happy with SportsBikeShop

Poor quality, hasn't lasted the test of time!

I purchased two of these to keep my bikes batteries going through winter. Within a year both have failed at the connectors that join the charger to the quick join connector from the battery. The device is poorly made and feels cheap, clearly Oxford have tried to cut costs by making it with cheaper materials. As usual sportsbikeshop have been excellent with the returns. I have purchased a replacement (different brand for similar money) and instantly can tell it's built a lot better. I would steer clear of this Oxford Oximiser, it's very cheaply made but without a particularly cheap price. I would expect better from a big brand like Oxford!

A must have !

Great piece of kit essential to keeping the battery in tip top condition. Leads slightly short but that's only a minor issue. As usual terrific service from sportsbikeshop.

Excellent value

A very good lower price, piece of technology: the unit has kept an older battery fully charged, and provided info in the process for several months now. I agree with comments about the Molex plugs: you have to be quite careful when plugging in the unit. I'm tempted to replace them with something more substantial but I fear that will void the warranty. And I know from previous purchases that SportsBikeShop are very good indeed on warranty issues. I would recommend this charger,

Works fine but material feels cheap

It does what it says but built quality isn't good. Cheap plasticky feel and they have really saved money on the plugs.. you have to push hard for them to connect. However it does trickle charge your battery, has a light and shows voltage of the battery.

A great top up battery charger

This is a great little unit for keeping your bike battery topped up, for example due to drain by an alarm over time. It is compact and comes with a lead to permanently attach to the battery making plugging in easy. It seems robust and my other Oxford charger has lasted years so should not be a problem. The only criticism is that the mains lead to the unit is quite short, 32 inch (compared to 56 inch on my other charger) and I don't need Oxfords web address in the display so the digits could then be larger.

Keeps battery topped up nicely

Cracking bit of kit. Two fixings, 1 permanently fitted to the battery that u just plug into charger and croc clips for the terminals for when u take battery off. Keeps battery topped up nicely, a warm welcome for the winter months when my bike's hibernating.

Questions and Answers

Questions and Answers

  • What length are cables that come with this, ie mains plug to charger and charger to bike. Also what difference between this and aniversary edition, same price except for a few coloured buttons on front ?

    September 20, 2018

    The measurements are approximately 34 inches from the plug to charger, the lead from the charger to the connector is around 37 inches, and there is around 12 inches length on the battery connection lead. There is no difference between this and the Anniversary Edition.

  • Is this charge suitable for Lithium Batteries. I have read some manufacturer statements saying as long as they are not left on for long periods and the chargers don't charge at 15+ volts they should be fine?

    January 29, 2018

    The only Oximiser that Oxford list that is suitable for lithium LifePO4 batteries is the 3X, and so we would not recommend using the Oximiser 900.

  • Can you use with DDA socket?

    January 11, 2018

    This cannot be used with a DDA socket. The Oxford battery chargers use the TM connections, but will come with a battery connection lead.

  • Can this oximiser be used with VRLA (valve regulated lead acid) battery, many thanks.

    December 6, 2017

    The Oximiser 900 can be used for VRLA type batteries.

  • I have a battery that says 'no quick charging' on it (, can I still use this charger/tender? I plan on taking the battery off the bike and leaving it on the charger for the winter. Thanks.

    December 4, 2017

    The Oxford Oximiser will be fine to maintain your battery.

  • Does this come with a EU plug too?

    November 28, 2017

    The Oximiser 900 is supplied as standard with a UK plug only.

  • Could you please advise how long is the wire connection from Oximiser to power point. Regards...David

    November 23, 2017

    We can confirm that the length of the wire (not including the plug) is approximately 34".

  • How are these with the outdoors? If I were to use it in my shed that doesn't offer a sealed environment away from the cold, would it cope?

    November 21, 2017

    We would not recommend this for outdoor use, but it will be fine in a shed (as long as it does not get wet)

  • I bought this item and connected it up. It charges on bulk charge 0.87 amps then drops to maintain at 0.25 amps. I left it on for two days, the battery shows 12.8 volts plus, but it won't turn the engine over enough to start. If I use my old style car charger it will charge up ok but doesn't hold the charge for more than a few days even with the oximiser attached. Any advice?

    November 6, 2017

    We would suggest either replacing your battery or asking an Auto-Electrician to check your regulator/rectifier.

  • Can you buy a 2nd set of connectors to be left on on a 2nd bike.

    October 30, 2017

    You can, you will need to purchase a TM71 Tecmate/Optimate connector (quick find number 2649, option number 3)

  • Can the optimiser 900 charge through a power socket (cigarette lighter type) if the socket is not wired through the ignition switch and has a separate fuse?

    March 6, 2017

    No, this unit does not come supplied with a 12V socket connection, only crocodile clips.

  • I have a 900 optimizer and its charging fine but what does "Bulk Charge " mean?

    March 3, 2017

    Bulk Fast Charge means that the Optimiser charges at a fast rate to bring the battery to approximately 85% capacity

  • Can I double check it will revive a flat battery? I would also like to know how it fits to the bike?

    March 1, 2017

    Optimisers can not always revive a flat battery as this will depend on how much it has already been discharged.( Heavily discharged batteries as low as 4.1 V can be charged if the battery is not damaged. The unit fits to the bikes battery via terminal leads which can be stored under the seat or fed through part of the bikes frame for easy access to the mains lead.

  • I have bought a new battery and need pour in the acid to activate it and then charge it. Will this charger work for this purpose?

    February 23, 2017

    This will be fine - let the battery stand for an hour before charging, and leave the cap off while charging for the first time.

  • Plugged my charger in after bike was standing for two weeks bike didn't start so plugged in to give it a top up.. kept flashing 10.2 volts for two hours.. took battery in to bike shop to check.. charged it 100%.. just don't understand why my oximiser wouldn't do it??

    February 20, 2017

    The Oximiser is designed to be plugged in and left on to maintain a battery,and so should really have been plugged in before leaving the bike for two weeks. The charger will go through cycles(recover, bulk charge and maintain) and two hours would not be long enough to give the battery a full charge. If this had been left on over night you should find that the battery would be fully charged.

  • Can you leave it on all over winter?

    January 28, 2017

    The Oximiser 900 can be left permanently connected to provide long-term battery care.

  • Do Oxford have a charger that can be used on both cars and bikes?

    December 7, 2011

    The Oxford Oximiser 3800 is capable of charging batteries from 1.2Ah up to 125Ah making it capable for car applications.

  • Does it mean you can connect it to your bike whilst you are riding it, or just when it is in storage?

    November 30, 2011

    The Oxford Oximiser comes supplied with a connection wire which can be permanently attached to your battery. The wire leading from the battery ends in a connection point which can be placed in a convenient position such as under the seat etc. This allows you the convenience of connecting directly to the Oximiser when the bike is not in use and then disconnecting before you go out on the road.
