What is the voltage of the Battery after being charged??

It's a 9 volt battery so when it's fully charged the voltage should be 9 volts.

It's the same unit. Voltage of a battery will vary somewhat based on its state of charge, so a statement of the voltage of a battery is a "nominal" value, not precise. This unit probably charges to a maximum of 40v, with a typical voltage of 36v and somewhat less as the charge is depleted.

The operation voltage of NiMH batteries is just 1.25V. When freshly charged, the terminal voltage may reach 1.4V or even slightly higher. Depending on the charging current and battery temperature, you may even see battery voltage reaching 1.5V. But this voltage will decay below 1.4V if you let the battery rest for a few hours. Bottom line is: your charger is working perfectly fine.

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.

My battery had a minimal charge when I RECEIVED it.I believe we are expected to fully charge it before using.

I have used it for 6 hours, and it still had a charge. Don't know average, I charge it after use.

I am not sure of the official answer, but I charged mine overnight. It has been working great!

Kate, battery charge rates vary depending on temperature, degree of discharge and age of the battery. With a new battery, at room temperature and in a normal state of discharge, about an hour will do it.

My new battery was already charged and I used it right away. Then when I loose a bar I charge it about 20 min. when the battery light stops flashing which indicates the battery is fully charged.

You may want to ask the seller that question. Here's what it says on the back of my charger: Input: 100 - 240 V ~ 50/60Hz 0.20A Output: 5.1 V --- 750mA Hope that helps.

I think that the voltage is about 15 volts. I leave mine charging my RV battery andhave no problem with it. It stays charging for months at a time.

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?

The voltage on this battery is 12v. The nominal chanrging rate listed for the battery is 15A with a peak charging rate at 30A. If you have a single battery with a charge controller at 30A, you should be just fine. However if you add a second battery this will drop to 15A per roughly, minus loss so you may not be able to fully charge your batteries based on your usage in a single day.

I'm not positive but I believe the one I bought put out AC voltage. I don't think that would work on charging a battery.

I'm not sure. I just got the closest thing to what I had before. Don't remember if this was the same voltage as my old battery. I got this new battery over a year ago & it's working fine.

Sorry, I do not know. I returned mine because it did not even turn on, even after being fully charged.

Mine was nearly fully charged when I received it. I have not run the battery completely dead during any single use yet, so I can't be certain. I would guess it should fully charge within an hour.
