I bought these 9v batteries and when I charge them the charging light never goes out to indicate they are fully charged. And they arent lasting very long. Are they faulty?

The batteries I purchased have been charging and operating fine. I'm sorry yours are not working well.

We were pleased with them initially but they have not lasted as long and some will only take one full charge.

I am not sure if I am qualified to answer that question, but I can try to help the best I can. How long do you try to recharge them? When I first received mine I had mine recharge almost till next day, when finally I got a green light letting me know it was charged. I heard about some batteries lose power quickly depending on what electronic device is used on. I use mine on a multimeter so not a daily or high energy consumption. I am not sure if these 9 volt batteries are high quality, but I would try exchanging them if you already recharge them to full in 24 hours. If they don't recharge within 24 hours max...then they are faulty. I hope this helped...sorry, I couldn't be of more help.

Plugged in to the battery lead and the the batteries have power, if they are then showing nothing, you either have the negative wrong or they are defective. One or the other. I would send a email and they should send you replacements.

they aren't full 9 volts. all of the devices i use them in work fine on their voltage. i just checked 1 of my spares that has ben sitting since feb and after 6 months it has 8.23 volts on a volt meter and on a battery checker it's meter is is as high in green as it goes. For us these last longer than any others we used rechargeable or none that's why we had one that's ben sitting 6 months

I've plugged in another brands battery pack like this and when I plugged it in, it instantly showed "fully charged" on it's indicators. However, I wasn't sure so pulled the plug on the charger and checked the battery voltage which was under 6V (showing that it was far from fully charged). So I plugged it back in for the 12+ hours and for the first hour, it stayed showing full (because the battery was resisting the charge power and the charger gave the lights the "full" 14V false reading), but as the battery began accepting the charge it dropped to 60% and then climbed back up over time. So don't be fooled by it showing that "full" within a few minutes, leave it plugged in for at least 12 hours (and by then it should be accepting the charge and the readings should have dropped, so once it raises again you can believe it's really "full".

I put the batteries in the charger that has indicator lights. So when the light is green, the battery is fully charged. If you do not have a charger with indicator lights, you might want to invest in this: http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords;=battery+tester I have a very inexpensive one of these that I use to test the loads of batteries I have in the house.

I have or had the same problem with the first set of new batteries that I ordered, they have sent me replacements but as of yet I haven't used them, but I will see if it helps with these and if it does I will write a response to you then. sorry

To be honest I did not discharge them first. I put them in the bays that worked. I had problems with a few of them. I now just tried the bays that did not work worked, but with a different kind of battery. There is something wrong with mine. Bummer

sounds like the batteries are nearing the end of life. mine does this now too, but they still charge. new batteries work as the manual says and the lights blink and slow to a stop. i have been milking these "old" batteries for a while and the charger not stopping is the only issue along with reduced fly time of course.

Well you have to put at least two batteries in at a time and there is a light above each spot for the two battries, so there are two lights. When you put only two battries in the lights will alternate back and forth to "find" the battries then one will stay on, green, above the battries you put in to tell you they are charging good. The empty spot will have no light. Then when the charging is complete the light will just turn off. I can't remember but I think the instructions said something about blinking and other colors like maybe orange or red to indicate "not charging" or "bad/used up" battery. But the short answer is yes green while chargeing then off for done and they can't be over charged.

They should get strong charge if placed in direct sunlight. Mine are lit and last about 6 hours because they are not in direct sublight. get one and put it where the sun hits and see if it last longer. If it doesnt then their batteey is weak.

The lights on my charger go out when the batteries are fully charged no matter what size battery. If you don't have one already, buy a battery tester (available from Amazon.com for $2.89) to be sure that the batteries can still hold a charge. If they cannot hold a full charge, this may be a reason why the lights stay on. Otherwise, I would return the unit. Hope this helps.

I have a problem, that might be related and I wanted to ask people as well. When I put the battery in the charger (I have two), most of the time, even though the battery is empty, the charger shows green light and does not charge. I have to put the battery in slightly elevated angle and push on it and then it will start charging. So maybe your batteries were not charged at first place. Also happens to me, that the batteries discharge if not in use for 2-3 days, so before use I always recharge.

There is a charging light that stays on while the battery is charging; the 'maximum charging' light does not stay on the entire time on mine, and mine works fine. So - maybe you should have yours checked out or return it..

I did not have this issue. Other have recommended checking to make sure you have the batteries in the charger correctly (+/-). If this does not help your issue I would contact Amazon and arrange a return/exchange since they are most likely defective. I recommend an exchange since these are otherwise decent batteries.

These batteries aren't as bad as NiCad batteries are at losing charge but they do lose some of their charge over time. However, this one seems to hold a high percentage of its charge for weeks at a time. Yours might be defective. If I haven't used it for a month or so, I usually charge it up anyway just to be safe.

Maybe it is defective. They are rather cheaply made. The light on USB goes on when I am charging and goes off when it is done as does the light on the charger itself. Judging by the other responses they do not all seem to work the same way.
