Works as planned Already have seen the benefit of this product. Charged my mower battery back to full in a day and I'm sure it will keep the bike ready for a ride next spring. November 23, 2015
Oximiser Ends Battery issues I got this charger and it has kept the battery well conditioned and sound. Bike has an Alarm on it so there is always a slight drain, but the Oximiser sorts all that out and has never let me down even through the winter. Bike never fails to start. Highly Recommend this for all bikers. August 19, 2015
The oxford 900 Optimiser is a must It's a very fast battery charger and very easy to use. It provides enough information while it's connected. And it works ok in 110v or 220v. January 2, 2015
Excellent for long term connection to battery The Oximiser 900 is easy to install and keeps the battery right at 12.7 volts. The best thing is the multi-stage charging. It can be connected to the battery for many months without damaging the battery. There is an inconsistency regarding input voltage. Labeling on the unit says 120VAC while the owner's manual says 120/220. If your service is 220 check with the manufacturer. December 22, 2014

Luciano S asked: Hello, I've bought the Oximiser 900B from Revzilla and I have a doubt about the input voltage. I need to use it in Argentina where the voltage is 220 VAC 50 Hz, when I look the user manual I see "Voltage AC: 110-220V AC, 50-60Hz" which is perfect but when I look the Oximiser's label I see "120 VAC, 60Hz". Could you please help me with this? Thanks!! Dec 18, 2014

Luciano S: Thank you Keith! I finally decided to take the risk, I plugged into the 220v outlet and it worked great. Dec 19, 2014

Larry D: Luciano: I see the same difference between the owners manual and the voltage information on the back of the charger. I am in the US where our voltage is 120 VAC, 60Hz. To be safe you should either email the company to get the answer or purchase a travel converter plug (should be about $5.00 US) that will have an output voltage of 120 VAC. The plug converter should also accept the blade type plug that is on the Oximiser.
I bought my Oximiser 900 last month. It keeps the battery on my Honda Silverwing right at 12.7 VDC even on days when the temperature is near freezing.
Good luck.

Keith P: Hi, I am not sure how much help I can offer as u am in a 110v country. It's better to confirm first but from what I understand if there is a voltage or charging issue with the Oximiser the indicator will turn red right away to alert of s problem when connected. Dec 18, 2014

A shopper asked: Hi,
Will this charge a battery that is completely flat, or does the battery need to have a small amount of charge for the charger to recognize that it is there?
Aug 28, 2015
Answer this · Send to friends Good question? Yes (0) No (0)
ANTHONY G: It will charge from flat but usually if a battery is that dead its time for a new one!
If the fattery has been elet go more then once there is permanent damage. I would use a larger cahrger first and use the oxford to maintain.
