Wanted a hassle-free way to deal with over-the-winter bike storage - in our unheated garage. Simple plug it in and forget it - works beautifully to keep battery in top charge all winter.

Oxford seems to make quality products are a reasonable price. I like them !
Luis C on Sep 29, 2016
i have 6 vehicles which all has a battery on it, since my battery charger had died on me after 20 years of using, the price of this item is at the same level of that previous one, plus new technology of managing the charging, it should serve my purpose of maintaining my battery as expected.,
Peng C on Aug 1, 2016
I like the "smart" capability of being able to leave it and have it charge accordingly. Plus with the new design out, this was on sale.
peter b on Jul 10, 2016
Good price

For all winter long charging

Features and closeout price
CHEMASALVADOR on Mar 17, 2016
Was on closeout and wanted a dedicated charger for my backup battery and this model seems rich in features. For the price, nothing else really tempted me. Have purchased other Oxford products in the past and love them. Quality products.

Excellent price, a very good unit with good features.

Can leave it plugged in and a good sale. I have three motorcycles that I ride year round and want to be ready to go.

Works with Lithium Ion batteries
Anthony M on Sep 30, 2017
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!!
Luciano S on Dec 18, 2014
BEST ANSWER: 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.
How is it hooked up to the battery? Do I need to constantly remove my seat or is there an aux cable with better access.
KEN W on Jan 26, 2017
BEST ANSWER: There is an aux cable that comes with the unit. No need to remove seat when using this.
Does the oxford Oximiser 900 come with a standard 2 or 3 prong power cord?
A shopper on Nov 16, 2014
BEST ANSWER: Two prong.
Is this tender waterproof? I'll be storing my bike outside and using an outside outlet. I do have the Rainex waterproof cover I could keep it under.
A shopper on Jun 7, 2015
BEST ANSWER: no rain or snow indoor only
Does the Oximiser 900 come with a "pigtail I can permanently attach to my battery ?
A shopper on Oct 31, 2017
BEST ANSWER: Yes it does.
Can this be used on the lightweight Shoria Lithium Ion batteries? I know my Optimate can't.

Kirk S on Nov 2, 2015
BEST ANSWER: It states itt will charge Lithium (and bought it because I plan on buying one eventually) but haven't charged a lithium battery yet.
Does this maintainer work with AGM (Antigravity Batteries)?
Thomas R on Jan 1, 2018
BEST ANSWER: AGM battery= Absorbent Glass Mat battery. Yes it works on AGM batteries. I use it on mine. Very good charger.
Hi, Will this charge a battery that has gone completely flat? I know some "smart" chargers require a small amount of charge in the battery to even recognize it is there. Thanks
Jason N on Aug 28, 2015
BEST ANSWER: In my experience you need at lest 2 volts on the battery for the charger to work correctly
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?
A shopper on Aug 28, 2015
BEST ANSWER: 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.
