What is the float voltage? When the charger indicates it is done charging what is the voltage of the battery?

Multimeter accross poles reads 13.62v when in maintain on my motocross bike. Hope this helps

I suggest testing the voltage with a multimeter on the main output wires and if its below 6.0v (considering a 2S lipo) your charger may be correct and you have a virtually dead lipo (damaged cells or esc over discharged) or if its above 7,4 it could be your charger (faulty) or one of the wires not making a 100% connection.

I'm not really sure. But I do know I only had this for a week and a half and the charger stop charging. Batteries work fine.

If memory serves, it was adjustable from ~11.8V to ~14.8V? I cannot remember exactly though (I have mine set for 13.8V to float charge)

Even though the battery voltage is reading 13.5 volts, it does not mean the batteries are fully charged. Fully charged should read 14.2 volts, that is when the soc will read full but only if there is no load on the batteries

I had this happen to me. Battery charger did not produce a charge of the battery. I got a new charger and everything works fine. I don't know how you would easily ascertain if the charger is bad except to see that the battery is not charged.

Are you sure the charger is working, I would check that first? If so, also suggest you might need to disassemble it to determine the battery model and type, then search online accordingly. Sorry - not a positive answer to your question.

It probably means float charging (slow charging)But in reality this internal charger is garbage like the rest of this unitMine died in less than a year (cheap crap you get what you pay for)

no it will continue charging but it wont go past 14.5 volts it will just stay at a float charge. that way the battery stays full because if it cut off the charge it will slowly drain.

I got a similar unit and when I first plugged it in, it too showed "fully charged". I then unplugged it and checked the battery level, but it instantly showed 0V. So that told me the "full charge" reading was false and the charger was giving me that reading while the battery seemed like an "open circuit" and was not accepting power yet. So I did leave it plugged in and within 1/2 hour it began dropping the reading to show 65% charged or such which I knew was more realistic. So despite getting that "full charge" reading off the bat, it does need the charge time. I got a similar unit and when I first plugged it in, it too showed "fully charged".

My charger makes a similar clicking sound in the float mode, which appears to be its normal cycling process. It's holding my batteries at 13.3 volts which is near ideal and is apparently not over-charging.

It should have a regulator that when it reaches full charge it will "float" the battery charge... try renogy Web site for more info or call them... I had a question and they were very helpful and knowledgeable

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!

the back of the charger says it is a 12V(max) Li-Ion charger. The input is 120 V AC 60Hz. I hope that helps. As a side note, the three batteries I purchased to be charged by this charger have all become duds in just a little over a year. The charger still seems to be working.

Most UPS units automatically charge and provide the proper "float" voltage to the battery once a full charge is achieved. If the battery no longer holds a charge, either the UPS charger is not functioning or the battery has reached the end of it's life cycle.

I advise u not to charge it with a different charger b'couse it may cause defect on it . The battery can support a certain A or volts but it was designed to measure when it's full charged or empty , what i'm trying to say it's u can short the batery life if u use the wrong charger .

Sounds like you could have a bad battery if it's only at 10.9v. (One bad cell?) What percentage charged does the unit show when first turned on? The voltage of the charger should initially go to ~14v-15v when first turned on. Can you test the charger on a known good battery?
