I connected this charger via the side plug to a new Odyssey deep cycle battery. I get this message when I attempt to select "deep cycle" on the right circular selector: "Check Connection or Battery &lt;1.25V." The display says that the battery is at %100....

Hook it up using the main cables when you select deep cycle. The side is only to maintain.

My battery works great, all day and I use it a lot. If you are sure that your battery charger is working, then you must have a bad battery. My battery came to me and had over half a charge when I got it. Exchange it and you will end up happy with the extended life battery.

I would have to look it up in the manual. Some deep cycle batteries like AGM's require a higher than standard voltage for charging. Perhaps you can download the Owners Manual pdf online.

I am not sure why it does it, but mine does it occasionally also. One thing you can check is to see what Amp hour you have it set for, It seems that when mine shows that I have had the Ah set wrong and it is showing that because I have had it set to a higher Ah battery than what I actually had. The battery will only take so many amps before the resistance gets too high and charge shuts off. If you have a 100 Ah batter and have the meter set to 200 Ah, The meter will show half full when the battery is full and the charge shuts off or goes into float mode from the controller. That is where I would look first. Make sure that you have the meter set right with the battery you have and then if it still shows 60%SOC you may have a bad one. But After I changed my settings, the meter seems to be reading correctly. It has actually gone to 100% Hope that works for you!

From what I understand from reading the owners manual, that indication is the chargers way of telling you that the battery is very discharged and is only at about 25% of its capacity. The LEDs are supposed to blink, not light up solid, as the charger is charging. If there is nothing wrong with the battery, the charge level should start going up after a while and in a few hours, the LEDs should read at 100% (solid, not blinking, red, red, yellow, green LEDs). I hope this helps you Mary! Michael R

Well yea, use a battery charger , or a deep cycle charger with a max of 35 amp .Most deep cycle batteries use a slow charge rate anyway which is a lower amp charger.Just keep the amp below 30 to 35 amp @ 12 volt. This is not a 24 or more system charger.

it is a balance charger but if you have a cell that became discharged below minimal voltage then its not going to fix that. However if the battery just got discharged unevenly somehow, it may recharge it to full capacity. I am guessing that the battery developed a short and is probably defective, but trying another charger may fix it (if it was not discharged too far). Just be extra careful when trying to charge that battery and monitor it. Hope this helps you to decide what to do! It is a good little charger for the money!

There is just the 2 red LEDs and 1 green one for the "charge level" indicators, correct? If so then seeing both red and the green LED come on when you push the test button does hint it is fully charged. If this is the first time you've charged it (where it can take 24 hours to charge), then I'd double check that it's full by pulling the plug on the charger and then push the test button again after 30 seconds. You should still get the 2 red LEDs, but probably not the green. If you have a volt-meter you can also check the battery voltage on the jumper cables, full is ~14V with the charger plugged in and without it plugged in it should drop to ~13V and hold there. If you suspect the battery being bad, then the way to test it is with a known load and see how low the voltage goes. For example, I plugged in a spot-light that pulls ~4 amps and a good battery had the voltage drop to 12.4V instantly and very slowly dropped the longer I had it on (like after a minute only dropped to 12.3V). A bad battery instantly dropped to 11.2V and within 30 seconds went down to 10.5V. That's how you can tell if it's really bad.

My Schumacher charger would let the battery drop to less than 50% without restarting. I believe there is a fault with the unit's processor. Schumacher support would not respond to my requests for a remedy. The remedy is to return it before the money back guarantee expires.

I'm not familiar with this part #. This charger works great for me. It actually works better than the old charger. If you left the battery in the old charger overnight, it would be very warm the next morning. With the new charger , it will be cool, both the battery and charger--this is good for the battery & power bill.

I just got my set and this charger does NOT work properly in a number of ways. When I put the Anker batteries in, the charger is BLUE from start to finish. 5 hours of charging yielded a 21% charge. When I put the stock battery in, pinkish purple all the way 6 hours to 91% charge. I suspect a bad charger, but I'm gonna do process of elim by charging the Anker batteries via USB. Regardless, my kit is going back because charger and/or batteries are bad.

Sorry not familiar with the charging of deep cycle batteries. Of course this can be used as it has a very gentile charging cycle. Spikes never got over 12.6 volts. That being said this charger charges more like a 1/2 or ever 1/4 amp charger it is very slow. However if your just going to hook it up and come back a month later it is a great charger. I can not remember if this model had temperature adjustments just something to keep in mind depending on your needs

The charger is ment for lipo batteries. 7.4 & 11.1 etc. I dont know what the connection is called for the charge side of a lipo. Hope that helps. None of the connections you mentioned would work for that.

I hope you didn't already buy this. I bought it and left my battery in it for 24 hrs and when I checked out it was only on 1% ! I'm not sure if it's suppose to let you know if it's charged or not b/c mine didn't come with instructions but my charger didn't let me know !!

I'm sure you have a knowledgable answer by now. I have only use my Tender on my BMW car battery and have not had this problem. I have a another charger I use on my Marine battery and it takes a long time to go from charging to low maintenance cycle.

I read that these batteries, if not used frequently used, tend to go dormant and the chargers will not charge. Need to connect battery to a regular battery charger to re-energize. Recommend you try to charge another battery or investigate the dormant battery issue for your specific equipment. Hope this helps.

I have two of the boats, so I have two chargers. The charging of the batteries is a bit clunky. Sometimes I will take what I think is a fully charged battery and as soon as it hits the water the remote starts beeping indicating a low battery. The boat runs fast and for a long time, so I'm pretty sure the low battery signal is flawed. Other times, the battery is fully charged and only lasts a short time. Sorry, that is no help, but your charger may be working fine and the boat/remote are acting weird...Happy boating.
