I am willing to try my charger, but would still prefer to have a fresh battery replacement when Jason replies. Thanks

also, what charge current would you use for the JD battery I can charge from .05A - 3A

It is of course frustrating to get something brand new and have it fail, but that is the nature of mass produced goods. Sometimes something misses getting caught in QA or gets damaged in transit. The sign of a good company is that they warrent the product and take care of you as quickly as possible.

To give a little perspective, I have two tales..

1. Verizon Wireless used to have a market research group called the Verizon Customer Council. There were about 50 active members, and we would receive new phones amd other devices (the first Android Tablet and the first MiFi device) a few days before public release, but after Beta. Of the 50, at least 2 and more often 3 or 4 would have outbof box failures or major problems. These were retail ready devices from the largest phone manufacturers packaged for the largest cell phone carrier. 4-8% out of box failures. DJ has shared that they have a 0.5% warranty claim rate. We know that is relatively accurate because we know that 10's of thousands of units have been sold, and to make a warranty claim, you need to post on the forum to try to get community support (where we help identify user error). There have been a few bad batteries, a few bad servos, a few bad cameras, and I think 3 bad EZ-B controllers. The first batch of ROLIs to ship had the H-bridge mis-wired, which the community figured out, saving the need for returns, and were missing 2 servos, which EZ-Robot shipped to all Roli purchasers whether they made a claim or not.

2. I am in the process of recovering my basement from a catastrophic plumbimg related flood. I had a lot of furniture there, and because of good insurance I am replacing about $5k worth of furniture and accessories.

So far, a clock we ordered arrived that would not keep time, a coffee table arrived cracked, and an ottoman arrived in the wrong color. About 4% of the purchases. The two furniture item were replaced for free. The clock I needed to pay return shipping although they did replace it. I will continue to buy from the two furniture companies involved. I will not be buying again from the company that sent the broken clock.

I start mine at 1A

This is the charger I use. I think it is discontinued now. I like the display because I can see the voltage of the battery, the charge rate as it a approaches peak, the mAh that is going in the battery, and I can set a max mAh so that it does not overcharge. At the time I got it, it was a $75 charger. It charges and balance charges through the balance port.

Oh, one more thing... You may have noticed that EZ-Robot has some passionate members of the community who are quite protective of the company. Please don't take anything any of us said as insulting your knowledge or right to complain if something isn't right, or us lecturing you on how to interact with a company. It is just a sign that EZ-Robot has been a really great company to work with (heck, the CEO has participated in this conversation) and has earned our respect (and some of us - cough @Richard R cough are just sarcastic by nature). Hopefully they will earn yours too and you will be just as passionate as the rest of us.

Alan, I appreciate your view on things and do understand that stuff happens and also learn from the experience I've encountered on this board. I now understand this group, appreciate it but will reserve my last judgement on my experience with the company for how quickly my customer service issue is resolved (which I hope all can agree is the ultimate sign of of a companies actions). Per DJ, I am trying to charge the battery with my charger, but I it still shows it as not lit its constant voltage indicator. I will without question still use my original tactic on big companies as coincidentally it worked wonderfully in getting Verizon to replace a defective phone with a newer model and offer me a discount on service, as well as get Sony to reimburse me and discount a camera which their customer service rep was not fully honest about shipping times. Everybody here has been great, I admit jumping the gun a bit now it's the companies turn to resolve a defective battery issue (I hope that is all it is, and I wouldn't know any better because this is my first real robot). I hope my future posts are trying t figure how to get the orientation add on or sonic distance add on as well as set up some AI for fun. This is why I bought this robot and this is why I was so excited and then so bummed that it's lying there. Hope all understand.

What should a fully charged batteries input voltage be?

somewhere between 8.00 volt and 8.30 volt
