I tested the battery by unplugging the power on my new TM822 for phone only. It lasted 3 hours with 5 min. talk time. Does that mean it's defective?

Factually, I do not know. You need to ask Arris. My guess is that it is not defective. It is intended to keep your phone active in a power failure. The time would depend on the number of phones it is powering and where it is in its charge/discharge cycle when the failure occurred. Also, initialization is strange. It arrives with no charge, goes through some sort of cycle back to no charge, and then takes several days to charge.

I don't know about your particular problem but I received a bad battery. The phone would show 5% and charging and after a few minutes would say it was fully charged but the phone would not boot up. I returned the bad battery and ordered another one from the same vendor. The new battery worked fine. Not sure if this is any help but wanted to share my experience.

I would immediately send it back. It has to be defective. My two batteries work just fine. They take the charge and hold it until you are ready to use them. Sorry to hear you had trouble. These are hi-tech units and I do suppose that they are a little temperamental.

Battery probably bad. If you let NiMH get absolutely flat (discharged) they CAN reverse polarity.

Hi there! I've been using this battery for a month in that same model and had no problems so far. Maybe it's a faulty one. If i were you, i would contact Anker support service. =)

I would take the battery out...let it sit. Then after 5 minutes put back in and see if it works OK...

I have had the battery less than a month. It is great so far. I would recommend that you find someone who has had the battery over a year. That is when my previous third-party battery from another company failed despite not being recharged much.

Sounds faulty to me. It has been a while since I bought my replacement battery and cannot recall if I had to charge it prior to use. All I know is that mine works great. Never have had a problem.

I think you must have gotten a faulty unit, mine lasts for at least a week on a full charge. I would contact support on that.

Could be a dead battery. Mine would last about 20-25 seconds and then die. Fixed when I replaced the battery.

Sorry for your problem with the battery install. If the new battery is not defective, sounds like the main unit is defective. I obtained the batteries as a gift for my daughter. She installed the new batteries and selected the option of new batteries installed. Then left the unit in the home dock, charging overnight. Went from running less that 5 min to completing the whole area for approx 50 min never having to go home for a recharge. Runs like new again

I purchased two of them and did not have any problems with them. I would check the battery or return it.

It's lasted a few 2 hour conversations and then the phone is returned to its' charger. Phones are usually left in their chargers so I can't really say how long they'd last on standby. Mine work well -- way longer than the old OEM batteries the phones came with.

Probably not. But it would help if you provided more information. What battery, cell count, mah and C rate. How old is the battery? What is the current draw at WOT? You are probably just over loading the battery.

I agree. Send it back. Mine has been perfect. Changed the battery once and it works great.

It's usually a battery problem, not a phone one! When I first got my S3 battery lasted about 20 hours after a full charge, now it lasts about 5, I use 3 different batteries a day using an external charger on one battery while using another on the phone and so on. My advice: get a new battery

It could be a bad battery. If it is a bad battery, you can call customer support, and they will send you a new one. They were very pleasant when I spoke with them about a battery issue not holding a charge. At the time, the customer service person told me that new batteries should be charged for at least 24 hours in order to keep a full charge. He also told me if the battery didn't work, that they would send me a new one.
