Customer Reviews for Oxford Oximiser 900
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.Read more
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.Read more
Very good product and excellent service as usualRead more
Quality bit of tech
Purchased this item as i had one previously for years worked faultlessly, only getting this new one as dropped old one in a bucket of paint! no coming back from that. Easy to use easy to read simple to use, ticks all the boxes!!Read more
Fit and Forget, well almost
Really easy to fit and once fitted you can almost forget it. After a ride I just Connect this to the bike and before a ride I disconnect, that's it. This little beauty makes sure the battery is in tip top condition 24/7. I have two bikes and both are fitted with the Oxford Oximiser 900.Read more
So far so good.
I bought this so when I've put the bike to bed for long periods of time I don't end up with a flat battery due to the alarm. Well so far so good. It appears to be doing what it's intended for and the UI is simple to interpret and use. The smallness of unit is also a bonus as the build quality (despite being plastic) appears robust and good.Read more
Super quick delivery, ideal for what I needed.. Fantastic price too.. Highly recommended.Read more
Excellent bit of kit
This is an excellent bit of kit. It does exactly what it says on the packet, very easy to connect to the battery and the 240v. The wall hanging bracket is very handy too, the unit can just slip in and out of it as you require. It charges and maintains the battery therefore it can stay permanently plugged in so that any alarm fitted will not drain the battery, I can't recommend it enough. Only one slight down side I feel that the leads 12v and/or 240v could have been a bit longer, although I think that you can but a 12v extension lead.Read more
Great service as always and a great product. Does exactly what it says on the tin. My alarm was draining the battery when I wasn't using the bike, this maintains the battery life like a dream. Easy to install and clear instructions for a DIYer. Would definitely recommend. 10/10.Read more

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 (https://www.batterylookup.com/Yuasa/GS_GT12B-4~), 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...DavidNovember 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.
