Excellent customer service and battery

I had my battery for about a year with no problems, It's overall a really high-quality battery. But after about a year, one of the charger ports started charging really slow. After a couple emails to Anker, they had another shipped out 2-day shipping!

Highly recommend! Customer service is really pleasant as well!

ORIGINAL REVIEW:
"Received the battery very early. Followed the instructions to condition the battery. Haven't noticed that the battery is lasting longer. I'm not sure if its a bad battery or what but I'm hoping it gets better."

UPDATE:
Dan from customer service contacted me about my problems.  They live up to their mission of treating others how you would like to be treated.  I have reservations about some companies but Hyperion is one I would recommend to everyone.  They are fantastic!

They are sending me a replacement.  They really want to make things better and make sure I don't have a defective battery.  You can't ask for better service than that.

Go ahead and buy a battery from them.  They won't let you down.

The delivery of the first order was partially damaged ( 1 of the 2 batteries ) postal delivery person dropped the box on the concrete outside our door - send photos of the damage to Chrome Battery - they promptly sent out 1 replacement right away - even when is was around the Thanksgiving holiday - Products and especially the customer service - top notch - they have my battery business now

The first battery did not work.  I contacted the company for a replacement.  A new battery was received in just a couple of days.  No questions asked.  Great customer service.
I would recommend this product and the company.

Purchased 12 months ago, used several times but it won't hold a charge anymore.  Disappointing since the original battery lasted 5+ years with minimal use.  I did reach out to the company via email/feedback -- hoping to hear back and perhaps update with better findings.

**UPDATE**: Customer service responded quickly and replaced my unit.  Very pleasant and followed through as promised.  Looking forward to using the replacement and appreciate their feedback.

I ordered 2 batteries at the same time, one of the batteries came in a nice little box with a balance connector protector and the other battery was just free, in the package with the connector already installed. The battery that was free had a cell die within the first 2 flights where as the battery that came in the box is one of my favorite batteries. After a little bit of back and forth with their costumer service, they sent me a new battery that works amazingly well. I recommend this brand and their costumer service, great people all around.

I got this package on Prime Day. It arrived on time and complete. One of the batteries would not fit in the battery compartment of my Canon T3i. The other battery was just fine. I contacted the company by email and they said they were sorry and offered a replacement battery which I accepted. It was mailed on the following Monday and and received on Wednesday. It was just fine. All batteries charged up and work great. This was an excellent deal and now I have a couple of extra back-ups plus a car connector if need be. Excellent customer service and a good price make this 5 STARS !!

Battery works well.  Customer service was friendly and very quick to respond when I was having setup problems.  Not the type of company that will allow for any funny business.  Highly recommended.

Received batteries with in one week, one worked fine and held charge for a week. The 2nd battery only had a charge for 1 day. Called the Company and they sent out a replacement, no questions ask. Very pleased with the customer service.

The first battery delivered did not work with my computer. So I had to return the defective one at my expense. That time and money makes the good deal not so good. The dealer did send a replacement for the defective battery right away. I mean within twenty four hours of my sending the email to them the new one arrived. That did make it sting a little less. This company offers good value at a fair price. I would recommend them and I will shop with them when my next need for a laptop battery arises. I would have given this product and company five stars if the return policy didn't penalize  the buyer.

The customer service is very responsive and polite. Had a couple of questions concerning the item. They were quite helpful. I need the back cover and battery replaced and they said they will do it promptly.

The person who helped me via telephone was wonderful and extremely patient.  The battery arrived practically overnight and I was able to install it myself.  I was delighted with the excellent service I received.

Battery and charging system work fine; the plastic tangs that keep the battery in the collar (and in the charger) broke after only a year.  Use care when inserting and removing from collar and charger!

--UPDATE --
While I still advise handling with care, I do want to mention that when I brought my issue to the attention of the seller, they didn't hesitate to send me a replacement battery at no charge...even slightly outside the warranty period.  I really appreciate great customer service like that and feel that justifies upgrading my review from 4 to 5 stars.  Thank you, Circuitcell!

I first bought this battery and 5 days later received it along with the charger. I noticed a problem right away, their are 3 blue lights on the external meter indicating how much power the battery has and I could not get the 3rd light to light up after a "full" charge, indicated by the charger. The battery also only lasted about an hour and ten minutes, I was hoping to get 2 and a half hours out of it on my Canon Vixia HF200. So I went through a few charging cycles with the battery, and still I was never able to get that last light to light up. I called Certified Battery and initially spoke to Jason, who then had Todd his supervisor call me back. We talked about the possible issue and solutions, and after a few more charging cycles just to make sure it wasn't working properly I started the RMA process. A gentleman named Bing does the RMA's, and he had prompt communication with me. 3 days later, today, I received my replacement battery. I charged this battery and after the first charge I got all lights lighting up, unlike my first battery. I put the battery into my Vixia HF200 to test it, and its now recorded 2 hours and 51 minutes, and still going. Much more then the stock Canon battery, and significantly less expensive.

Thanks to Jason, Todd and Bing I have full confidence in Certified Battery, even if I did have to send back the first battery. They sent me a replacement battery before I even sent the original one back, GREAT service, great product and great company.

The first item sent to me was defective. The seller sent me a replacement battery. It works great. The service is excellent.

This larger battery did not originally fit my APC-750. Instead, I needed the 12 8Ah model sold by Mighty Max. However, when I contacted Mighty Max, their incredible customer service responded very quickly and explained they would replace my too-large battery with the correct size-- free of charge. I was amazed. They went above and beyond to make me as a customer happy. I would highly recommend whatever they sell by virtue of their customer service alone.

I first received this product and it worked ok but had an average run time and my first review reflected that.  This second review is a follow up on that.

However, I will say that I am pleasantly surprised at the customer service of Iottie.  They contacted me and were willing to ship free of charge a second battery for my Roomba.

So I will say I am impressed at the level of customer service from this company, it is not everyday that companies pay attention to their reviews and respond.

As far as the battery goes, since I just received the replacement, I don't know how this ones run time is, but I can give Iottie lot of credit for its willingness to make the customer happy.

UPDATE: These batteries just don't last.  Even thought the company works hard to keep their rating intact, the batteries are not good quality.
